kernel gentoo-3.2.0 + .asoundrc = trouble

[APolozov]

I update my current kernel (~amd64) from 3.1.7 to 3.2.0 by "make oldconfig"
After boot I see that my alsa don't use my ~/.asoundrc, dmix not declared, kde blocked sound device, and mplayer work withaut sound.
I reboot to 3.1.7 - alsa is normal work
How I need to read about .aoundrc into kernel-3.2.0?

[Dorsai!]

if you are on a single user system, I suggest trying to paste the same config to /etc/asound.conf
I am using kernel 3.2.0 with that and it works fine so far.

For the actual reason why .asound.rc is not working, I have no idea. Normally that shouldn't have anything to do with the kernel and is read by alsa-lib in userspace. The kernel only provides the pcm hw devices.

[APolozov]

I did copy ~/.asoundrc into /etc/asound.conf but It don't help me.

[Dorsai!]

Can you post your .asound.rc?

Also, check the outputs of the following commands and look for differences between both kernels:

"cat /proc/asound/cards"
"aplay -L"
"aplay -l"

I re-run alsaconf and the differences between the old and the new /etc/modprble.d/alsa.conf are:

Still no sound at all.

[APolozov]

You can probe it:
sudo rmmod -f snd-hda-intel
sudo /init.d/alsasound restart
test yor sound (run mplayer for example)

[dracula1985]

I've done it before logging in on KDE (doing it after the logon results on a infinite wait for rmmod) and still no sound at all.

[Dorsai!]

The problem obviously has nothing to do with asound.conf.

My guess is there is trouble with the snd-intel-hda module (or the codec you both might share) again. If you have time you could look through the release notes of 3.2.0 if the intel-hda module got any dramatic changes this release.

I use snd-sbxfi and snd-hdsp and I am fine in this release.

[APolozov]

Are you using nonstandart configuration on ~/.asoundrc or use your soundcard by default settinigs?
By default my hda-intel soundcard perfect work but I want to use myself configuration with dmix and duplicate channel

[Dorsai!]

Yes, I am using a quite extensive asound.conf for dmix over SPDIF of my X-Fi and low latency dshare of my RME HDSP. I would have no sound at all if asound.conf didnt work.

You could check if alsa-lib is compiled with all necessery USE flags and ALSA_PCM_PLUGINS="dmix ..." but I would not see what should have changed there.

Also:

Code: Select all

default 
    Моя звуковуха 

If this is output under the 3.2.0 kernel this would indicate that your .asound.rc is read and used. So the question rather is why dmix does not work under the new kernel.

Code: Select all

pcm.dmix-xfi  {
    type dmix
    ipc_key 1024
    ipc_perm 0666
#    ipc_key_add_uid true
    slave {
       pcm "hw:XFi,4"
       format S32_LE
       period_time 0
       period_size 2024
       buffer_time 0
       buffer_size 16384
#       buffer_size 512
       rate 44100
       channels = 2
    }
}

This is my dmix section. The only real difference is that I specified a device (hw:0,0 instead of hw:0 for you), and that I specified a format.

Can you post the output of "aplay something.wav" if you try to play some wave file with it? It should show you in what step of your signal chain the error appears.

I don't know where to find kernel 3.2 release notes, on kernel.org the stable version is still 3.1.8.

I downloaded the patch for 3.1.8 and 3.2 and made a "grep snd.hda {patch}".
On 3.1.8 there are 39 rows and on 3.2 there are 221 rows.
So I can say that, on kernel 3.2, snd_hda_intel has changed a lot.
But I still don't know how to resolve the problem...

I'll try to change the "model" module's param, maybe testing all the avaiable values I can find on Documentation/sound/alsa/HD-Audio-Models.txt

[dracula1985]

I've done this test:

I've created a file HD-Audio-Models.txt containing all the snd-hda-intel models:

Some of them (like dell-s14 and hp-dv7-4000) played noise from integrated speakers instead of connected headphones, the others no sound at all.

[APolozov]

Can you post the output of "aplay something.wav" if you try to play some wave file with it? It should show you in what step of your signal chain the error appears.

I have this answer

Code: Select all

ALSA lib pcm_direct.c:936:(snd1_pcm_direct_initialize_slave) unable to set buffer size
ALSA lib pcm_dmix.c:1030:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:660: audio open error: Invalid argument

[Dorsai!]

You could try a smaller buffer size.
After all "buffer_size 65536" is more than a second in your configuration.

Try buffer_size 16384 like in my configuration or even smaller.

Some of them (like dell-s14 and hp-dv7-4000) played noise from integrated speakers instead of connected headphones, the others no sound at all.

Those that played noise should be the ones that "work". aplay does not support mp3 so it played your mp3 as a raw file using your default sample rate and format.

[dracula1985]

Specifing model=dell-s14 everything works, except for the docking station headphone port.
The other models working during the test (dell-vostro-3500 and hp-dv7-4000) doesn't work at boot, I can't hear any sound, maybe, as told by APolozov, I have to unload the module and restart alsa to make them work.

I think this is a big regression between kernel 3.1.6 and 3.2.0

[APolozov]

I probe to set-up your buffer size - the same simptoms
IMHO creating virtual sound device (into my config dmixer and default) into kernel 3.2.0 is broken
It's path may be?

commit | commitdiff | tree
Takashi Iwai [Thu, 10 Nov 2011 11:28:38 +0000]
ALSA: hda - Don't add elements of other codecs to vmaster slave

When a virtual mater control is created, the driver looks for slave
elements from the assigned card instance.  But this may include the
elements of other codecs when multiple codecs are on the same HD-audio
bus.  This works at the first time, but it'll give Oops when it's once
freed and re-created via reconfig sysfs.

This patch changes the element-look-up strategy to limit only to the
mixer elements of the same codec.

Kernel updated to 3.2.1 - the same trouble.

[Dorsai!]

I tried to find the kernel changelog for 3.2.0, but it seems to be missing from the kernel.org filesystem:

http://kernel.org/pub/linux/kernel/v3.x/

Very strange

[dracula1985]

Fixed with sys-kernel/gentoo-source-3.2.1 for me, no more need to specify model parameter, everything works as with sys-kernel/gentoo-source-3.1.6
