[SOLVED]Audio devices change at boot randomly. PulseAudio problem

RJQ · 2012-04-02 18:51:49

I am wondering if there is an actual solution for this problem,

I am using the sound from the HDMI cable from a nvidia card, the problem is that in order to use it I need to specify statically the device (hw:1,9 in my case) on the /pulse/default.pa file, but for some odd reason the devices change randomly at boot making pulseaudio unable to start and this prevents me too from starting it manually. If I do not use the load-module option then the devices are detected and named correctly but then the wrong device is used by pulseaudio muting the whole system.

I am on a Gnome box, the same thing happen to my other partitions but I they have KDE which tend to auto-correct the problem and there is no pulseaudio there but I notice the device's names also change randomly.

If this is a hardware issue could a dedicated sound card solve it, or would it happen the same thing all over, I can't use the integrated chip either because it is faulty with really low volume.

Any suggestions or comments are much appreciated.

Edit:
Following the steps in the Ubuntu post did it, it is a bit outdated therefor it needs a couple of modifications for a Arch box in short:

make a sound.conf file

# nano /etc/modprobe.d/sound.conf

write the options parameter on it in my case is the 1.9 device in nvidia

options snd-hda-intel probe_mask=0x108

generate the linux image

# mkinitcpio -p linux

edit the pulse default.pa file

# nano /etc/pulse/default.pa

add to the file in the "load-modules statically" section

load-module module-alsa-sink device=hdmi:NVidia

in case of alsa errors at boot delete asound.state file from alsa and set it again

# rm /var/lib/alsa/asound.state
# alsactl store

so far is working good.

Have you read this solution? https://bbs.archlinux.org/viewtopic.php?id=138432

Thanks Connor for the link, I did read it before and the other bunch in this thread : ) but it wasn't clear as on how you go with the asound.conf file, last night I found a slightly more elaborated version of this solution in a old post from the Ubuntu forums http://ubuntuforums.org/showthread.php?t=1668737 although the whole thing about mask still obscure to me in how they got it, luckily my card is nvidia too with similar devices, so far after four reboots is going o.k. but would see if after a week this asound.conf tweaking is in fact a solution or not.

The other thing here is that asoun.conf is not mention in the pulseaudio wiki? or I did skip it.
