 |
|
Hello,
I arrived at a point where I do not know what else to do than ask for help.
I've setup a Gentoo system and ended up with everyhing working but sound.
I double-check my kernel config and globally enabled USE=alsa in make.conf,
followed by | Code: | | emerge --newuse --deep |
.
Also I installed media-sound/alsa-utils and added alsasound to the boot
runlevel.
After a reboot,
listed the following devices:
| Code: | null

surround71:CARD=Generic,DEV=0

7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
|
I am primarily interested in analogue stereo output to my desktop speakers or
headphones connected to the center out of my motherboard.
However, having the HDMI out work as well in case I need it in the future would
be a plus.
I tried running but got an error:
| Code: |
speaker-test 1.2.3
Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.3.2-r1/work/alsa-lib-1.2.3.2/src/pcm/pcm_dmix.c:1090:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory
|
Following https://wiki.gentoo.org/wiki/ALSA#Files, I created /etc/asound.conf to set the ddefault device to 'Generic'.
Then,
| Code: | speaker-test -t wav -c 2
|
was working just as expected.
Next, I tried playing audio via the web browser (www-client/qutebrowser)
using the following test website: https://midimusic.github.io/browsertest/#self
I could see the player moving through the song but there was no audio.
Of course I checked alsamixer and my plackback devices were no muted or
anything like that.
As a next test, I downloaded the an Ogg file from that very same test site,
installed mpv and tried to play it: No issues here.
So I have audio, but not in the browser, using the exact same file for testing.
Originally I had skipped over
https://wiki.gentoo.org/wiki/ALSA#Laptops_with_HDMI_audio_output, since it
specifically mentions Laptops and Firefox but on second look I understood that
I might need to remap my 'Generic' sound card as 'card0' and the 'HDMI' one as
'card1' to switch the default device for my browser.
Unfortunately, I do not have any test equipment to connect via HDMI to confirm
I get output there. Also, on my Laptop, where I have the same setup (ALSA only,
qutebrowser, analogue audio + HDMI audio), the order happened to be correct
without me ever having to change anything:
| Code: | cat /proc/asound/cards
|
| Code: | 0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf5220000 irq 32
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xf3000000 irq 17
|
Since I had compiled HD Audio support into my kernel, not as a module, the
modprobe-based solution suggested in
https://wiki.gentoo.org/wiki/ALSA#Laptops_with_HDMI_audio_output was of no use.
Instead, I modiefied my kernel command line as suggested in
https://wiki.gentoo.org/wiki/ALSA#HTML5_does_not_play_in_the_Firefox_browser.
With the 'snd-hda-intel.index=1,0' boot parameter, the order of cards was
fixed:
| Code: | 0 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfcc00000 irq 74
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xfc960000 irq 72
|
I confirmed that both speaker-test and mpv work just fine now, even without any /ect/asound.conf (or ~/.asoundrc for that matter).
However, there still is no audio in qutebrowser.
Since more or less the same setup is working fine on my other machine, I do not
know how to further troubleshoot this.
Both systems run without systemd but use elogind.
Also, I use the same USE flags for dev-qt/qtwebengine (alsa -bindist
-pulseaudio system-ffmpeg) on both systems.
However, the old system (with audio in the browser) is using X, and the new one
(without audio in the browser) Wayland.
So if you can suggest other browsers to test that don't require me to switch to
systemd + pulseaudio + X + Gtk when I want OpenRC + ALSA + Wayland + Qt, I'd
give those a try though my gut feeling tells me it's not the browser that is to
blame but something in my (ALSA?) configuration.
Also worth mentioning might be that while both systems run a non-desktop
profile, the old one is using plain default/linux/amd64/17.1 while the new
one is using the hardened version of the same profile.
I really don't know much about sound configuration but ever since OSS stopped
being a thing I never ran into any issues using just ALSA 'out of the box'
until now.
I tried various asound.conf examples I found all over the net, maybe
understanding half of them a quarter each, but whatever I tried, I usually
ended up with working audio in both speaker-test and mpv but never once got
any sound out of qutebrowser.
So I would be very happy about some pointers on how to figure out what I am
doing wrong (other than not 'simply running Unbuntu'). 
Thank you in advance for your help.

You didn't post .asoundrc configuration but just maybe if you specified rate in there and it's over 48000 then that might be the reason.
For example I don't have sound in firefox if rate is not 48000, that's the max that browser can support, if it's higher then it will not produce sound.
Don't know about qutebrowser though, but you might want to try in your config

Thank you for the quick response.
I might not have made it clear, but I am not using any ~/.asoundrc (nor /etc/asound.conf).
I did try various version I found online, some including lines referring to rates, but no of them helped.
Also, on my other system, I am using ALSA only without any extra configuration (no ~/.asoundrc, no /etc/asound.conf) with the same browser (though different hardware) and it works.
I'd like to give you suggestion a try though but I want to make sure I understand how to do that exactly.
Starting with no ~/.asoundrc at all, would simply dropping that single line be all I need to do?
And if so, how do I make sure it is 'enabled'? Do I need to restart the browser? Restart the alsasound rc-service? Re-login with my user? Reboot the entire system?
Sorry if those are stupid questions but I wouldn't want to waste your time by 'trying' your suggestion but doing so wrong.
If there is any good (concise) documentation on this, I was not able to find it. So feel free to point me in the right direction if you know where I should find the information I seek.
edit: I did try adding that single line to ~/.asoundrc and restarting my browser: Nothing changed.
Also note that even without any ~/.asoundrc, mpv reports | Code: | AO: [alsa] 48000Hz mono 1ch float
|
when successfully playing back the test Ogg file.
Also, I am not sure to what extent one can extrapolate from Firefox since (according to https://wiki.gentoo.org/wiki/ALSA#Firefox.2C_Chromium.2C_and_YouTube_have_no_audio_with_custom_.asoundrc_but_other_apps_do) it requires PulseAudio and I am running an ALSA-only setup. |

You don't need to restart anything when you change something in .asoundrc, except if the sound is already used, then just stop it and start it again, to be safe.
Now, like I said, that's what got Firefox working for me with sound, without it there was no sound
It was worth a try for qutebrowser but it might not work, simply because it's possible that there's no alsa support at all for that browser, but I really can't tell that.
You might want to check this thread, it's for firefox but you might find something useful in there for your case.
https://forums.gentoo.org/viewtopic-t-1112504-postdays-0-postorder-asc-highlight-firefox-start-25.html
you can copy/paste that config file (.asoundrc) , just make sure you have the card number correct for your setup |

Firefox sounds works fine with alsa only, but may need asound.

OK. Then the conclusion is that I tried that and it did not work.

Like I tried to point out several times before: I am using that exact same browser on another ALSA-only Gentoo system (also with both analogue system audio and digital HDMI audio) for years without any issues.
The browser is based on qtwebengine which I emerged with `USE=alsa`.
So there definitively is ALSA support for that browser.
edit: Also, if that already slipped through, let me reiterate as well that there never was the need for any manual alsa configuration on that system. I have sound in qutebrowser without PA, without ~/.asoundrc, and wiithout /etc/asound.conf using the same test site right now. Just not on my new system.
Thank you. I'll have a look.
edit: I tried the following ~/.asoundrc:
| Code: | pcm.onboard_card {
type hw
card 0
format S32_LE
rate 48000
}
pcm.dmixplug {
type plug
slave.pcm "dmixer"
}
pcm.dmixer {
type dmix # multi-stream mixing
ipc_key 4897
slave {
pcm "onboard_card"
channels 2 # adjust as necessary (e.g. 8 for 7.1 audio)
format S32_LE
rate 48000
period_time 0
period_size 1024 # double if you notice increased CPU load or crackling
buffer_time 0
buffer_size 8192 # some applications do not like smaller buffers
}
}
pcm.!default pcm.dmixplug
|
This is exactly what you referenced, with the card changed from '2' to '0' in the third line since my 'Generic' device is 'card0'.
I restarted the browser and there was silence.

Good to know. Maybe then the Wiki should be updated to reflect that.
edit: Reading the thread linked above, I noticed that this restriction refers to the binary package only and going back to the Wiki it points that out as well. I just misread that part. Sorry for the noise.
But for my problem this information does not really give me anything new to try, does it? |

Well, if the sound is not working only in qutebrowser then the problem is obviously in the qtwebengine or there's some bug in qutebrowser.
Are the versions of both packages the same or are they different, when you compare new vs old system (where the sound works) ?
If they are not, try matching those versions in the new system to be the same as in old one. |

Is that the case? How do I know it is only qutebrowser? Does the browser directly talk to the kernel or are there layers in-between that could be different for mpv?

They actually are no but chances are low the very latest update broke sound after a decade of never having such issues.
`qtwebengine` takes many hours to compile, so I can't check quickly. Also, I can't match the USE flags since I use X on one but Wayland on the other sytstem.
I can try to downgrade on the new system overnight though.
edit: Actually, the qtwebengine versions match and that part of qt does not have X or wayland USE flags. So all I need to do is match the qutebrowser version and I am confidenent enough that this won't be the issue, that I decided to update the old system right away to match the new one. So let's see if that breaks browser audio on my old machine. |

Well, you said that mpv played ogg file with sound working, so I guess it's just qutebrowser.
If possible try to find other apps not producing sound as well.
I understand it takes a very long time to compile qtwebengine, system profile and X or no X (wayland) shouldn't matter in this case.
Not saying that would fix the problem anyway, but it's interesting that it's working on one and not on the other system, with same specs more or less.
So, the logical thing to me is to match what's possible from the working system.
It could be the hardened profile, I mean I run on hardened profile but I can't remember having sound issues, I had some graphical problems.
In any case here's my USE settings from make.conf, after -elogind is what I added to make hardened profile works for me with no issues, again I can't remember if the sound wasn't working, I think it worked though.
| Code: | USE="-consolekit speex alsa -pulseaudio ffmpeg -libav -gnome -kde -systemd -bluetooth -ipv6 -cups zsh-completion -qt4 offensive vdpau vulkan -avahi -zeroconf -geolocation -gnome-online-accounts cryptsetup crypt

So the update finished and also with the matching qutebrowser version, sound is still just fine on the old system

I see the logic but I was hoping to find someone you knows what I did wrong.
But good guesses are better than nothing.

I agree but my time to experiment is limited so I'd enjoy moving forward.

Good thoughts: Here are the global USE flags on the old system:
| Code: | | USE="a52 aac aalibs acl acpi alsa amd64 apm atm bcmath berkdb bidi bzip2 cdda cddb cdr cli crypt cscope css cups dri dts dvd dvdr emboss encode enscript fbcon fftw flac fortran ftp gdbm geoip ggi gif gimp ginal git gnuplot gphoto2 gpm graphviz gsl hscolour iconv icq id3tag ieee1394 imap ipv6 lame latex libcaca libglvnd libtirpc lm_sensors lua maildir mp3 mp4 mpeg mplayer msn multilib musicbrainz mx ncurses nls nocd nptl oog openmp pam pcmcia pcre pdf pie plotutils png posix python readline seccomp smp sound spell split-usr sse sse2 ssl svg symlink tcpd thinkpad threads tiff truetype unicode usb vcd vim-syntax vorbis vpx wifi win32codecs xattr zlib zsh-completion" |
and here on the new one:
| Code: | | USE="acl alsa amd64 bzip2 crypt elogind hardened iconv ipv6 libglvnd libtirpc multilib ncurses nls nptl openmp pam pcre pie readline seccomp split-usr ssl ssp unicode xattr xtpax zlib" |
Any insights which ones to experiment with first? |

You can try to play some video files with mpv on your drive
Or you can play youtube videos directly with mpv, like this one from the test browser page you posted
| Code: | | mpv https://youtu.be/8Pu3XSCH2L8 |
or maybe you can try to emerge firefox-bin and then play youtube video and see if there's sound
yes, firefox-bin use apulse but at least you would know that everything else on your system is right and that there's a problem with qtwebengine or qutebrowser itself , for some reason
can't really help you more than that, would have to install qutebrowser and qtwebengine in order to know more about this issue you're having
and I don't feel like doing that, it's been a very long time since I've installed anything that would require any *webkit, sorry  |

Just reporting back that I got sound to work on my system.
Unfortunately, I do not know what did the trick:
I eventually decided to switch from pure ALSA to Pipewire, also enabling USE=pulseaudio globally (with Pipweire acting as the PA server).
While setting this up, but before Pipewire was actually running, I had audio in my browser.
Maybe I pulled in pulseaudio and it launched due to autospawn being (still) enabled, maybe increasining CONFIG_SND_HDA_PREALLOC_SIZE for Pulseaudio already did something. Maybe it was something else entirely.
Either way, while I would not consider this 'solved' (I still do have ALSA-only systems with sound in the same browser, so what I tried originally should be possible), I am not going to follow up on this.
Not sure if there is a way to mark a topic as closed but not solved or if to just leave it open, but at least I wanted to follow up here.
Thank you again for your help. |

All such markings are just text in the thread title, and placed/spelled according to convention. You can put the word CLOSED there instead of SOLVED if you like, or anything else reasonable. Just beware the text length limit. You won't be able to put a detailed commentary into the title, but you could include that as a new first paragraph in the top post. |

When firefox/browsers doesn't work, well.
What here helped me the XXXnd time is, - what I ever forget to do:
RATE ... (rate?yes?) 48000!
That's perfect for now. And no pulseaudio or apulse is really needed as I see. |

Foun it, thanks. I'm sure I've got it set, as ALSA works great all the time, but I need to add it to my notes.

On my ALSA-only system, I have neither ~/.asoundrc nor /etc/alsa.conf while ALSA always just works fine. I do have apulse installed.
| Code: | $ lspci | grep -i aud
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05)
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Turks HDMI Audio [Radeon HD 6500/6600 / 6700M Series] |
I DO have /usr/share/alsa which contains an alsa.conf as well as an alsa.conf.d and apparently the defaults are working well.
| Code: | $ grep 48000 /usr/share/alsa/alsa.conf
defaults.pcm.dmix.rate 48000 |
