 |
|
Seriously, wtf is wrong with the database? Who thought that 60 characters would be enough?!
Allright, to my problem:
This morning, for a mere laugh, I decided to unmerge media-libs/alsa-lib-1.0.27.2, and after a reboot I decided to merge it again. It does not matter why I did it, what matters is that my notebook, once capable of playing sound, now is mute. Totally. Not one single bling, not in VLC, not in Xfce, not in Firefox - sound is dead.
I didn't change much expect for:
- recompiling and starting a new kernel (but that can't have any effect simply because I tried to get sound with the old kernel and the same user space as well, and it didn't work, so this problem is to be found entirely in the user space).
- rebooting once to Windows (got a dual-boot system) and then booted back to Gentoo.
- extracting the EDID from my monitor and included it as kernel blob so that it does not have to perform the DDC handshake.
What I tried/searched/yelled at:
lspci -k: the snd_hda_intel module is there.
cat /proc/asound/cards:
| Code: |
0 [HDMI ]: HDA-Intel - HDA Intel HDMI
HDA Intel HDMI at 0xf7a14000 irq 46
1 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7a10000 irq 45
|
I don't use the first sound card btw, I use the PCM card ... at least I hope so. I cannot really tell because sound always worked for me with this ~/.asoundrc:
| Code: |
defaults.pcm.!card 1
default
{
card 1
}
|
The device is missing, so I don't really know if it's the first or the second one. I do assume it's the first one thought, because alsamixer (I checked that one as well) shows me no options for the HDMI carc, also I deactivated the HDMI codecs in my kernel. 
I added "device 1" thought, but no effect. System can be considered as update to date, just emerge --update --newuse --deep --with-bdeps=y @world'ed
I might add that even before kernel switching I was using a strict monolithical kernel, that is, everything is compiled in directly and is not available as a module, and it worked out. Strictly spoken: there's no reason to assume that a broken modprobe configuration in /etc/modprobe.d/ caused the problem, as ALSA was brought up long before the first sync with the hard disk is done. |

As it so happens ... that was my first try.
Hardware detection ... check.
| Code: |
00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06)
00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 05)
|
Kernel (wtf I didn't chang that, but OK) ... check.
alsa flag in /etc/portate/make.conf ... check.
alsa-utils merged ... check.
User in audio group ... check.
| Code: |
cat /etc/group | grep 'audio'
audio:x:18:dachschaden
|
Linux is sometimes like Windows, so what about restarting the service (/etc/init.d/alsasound)? ... no, check.
alsamixer is a big fat check.
Speaker test ... checked, but I haven't got anything. The same as with VLC.
aplay -L? Well, it's not checked, but for you:
| Code: |
null
Discard all samples (playback) or generate zero samples (capture)
hdmi:CARD=HDMI,DEV=0
HDA Intel HDMI, ID 2807 Digital
HDMI Audio Output
default:CARD=PCH
HDA Intel PCH, ID 668 Analog

|
~/.asoundrc, and checked.
<Skipping all that part about HDMI>
aplay --list-devices ... huh, not checked? OK ... (Output is in german, my native language, but the format stays the same):
| Code: |
Karte 0: HDMI [HDA Intel HDMI], Gerät 3: ID 2807 Digital [ID 2807 Digital]
Sub-Geräte: 1/1
Sub-Gerät #0: subdevice #0
Karte 1: PCH [HDA Intel PCH], Gerät 0: ID 668 Analog [ID 668 Analog]
Sub-Geräte: 1/1
Sub-Gerät #0: subdevice #0
|
<Skipping the desert about A/52 /Dolby...>
I don't use JACK or pulseaudio or whatever, so this can't be the problem.
I don't wanna use my mic ...
Troubeshooting section does not match of my problem in one single case ...
More detailed infos about the alsa stream? Sure, go on ...
[EDIT]This was removed because it would give people with the same problem a shock, and then they are likely to just skip ahead[/EDIT]

Sorry you're having trouble.
I see a lot of 'mute=1', can you switch devices in alsamixer, with F6 , and try to unmute anything |

It occured to me just right now that I could give CTRL+SHIFT+C a try ...
===============================================================
EDIT:
===============================================================
Okay, I fixed it. I am soooooo fuckin' stupid ... gnarf. Sorry, I am really sorry wasting all your time.
I should have noticed the
and that it was there for a reason. I am sorry, really. I have no idea how it got muted, but it was. Just pressing "M" in alsamixer fixed it for me. Again, I am sorry.
I shouldn't do Gentoo with such an airhead.  |

dachschaden,
Everything muted is a safe default. It saves destroying your sound system/hearing until you are ready.
You have learned this in a such a way that you won't forget.
Enjoy your Gentoo
