alsa no sound

hi for some reason my sound stopped working.
it used to work fine after i ran the following commands as root
# amixer set Master 90% unmute
# amixer set PCM 85% unmute

now i still don't have any sound after unmuting . I tried re-installing alsa-lib and alsa-utils
but no luck.  Does anyone have any idea what went wrong/how to fix it?

i recently did a pacman -Syu so that might have had something to do with it.

thanks.

Re: alsa no sound

Did you re-run alsaconf?

Re: alsa no sound

Is it on a laptop by any chance, i had a similar problem once and i tried modprobe -r my sound module but got an error snd-hda-intel in use so i put the laptop into suspend then on resume i had sound again

Re: alsa no sound

Did you add  the following line to modprobe.conf?

option snd_intel8x0 index=0

Re: alsa no sound

This is probably a stupid question, but have you tried to set the volume using 'alsamixer' as a normal user and as a root user?

Re: alsa no sound

So, I've got the same issue.  It appears the hardware is detected OK, but no devices actually show up.

Poking around led me to this post:
https://answers.launchpad.net/ubuntu/+s … tion/85510

Basically, states that alsa-lib and alsa driver should be the same version or this error will occur.  They are not the same version on my machine:

Driver version:     1.0.20
Library version:    1.0.21a
Utilities version:  1.0.21

Don't want to recompile alsa from scratch unless I have to.  This is my first attempt at arch linux...

Re: alsa no sound

I have the exact same issue. Headphones work great, but I get no sound from the speakers.

I have the same driver mismatch as you. Did you manage to solve this problem?

Re: alsa no sound

After checking the docs in www.alsa-project.org and having a bit of luck I read in the alsa-driver changelog "ALSA: hda: Use model=auto quirk for Sony VAIO VGN-FW170J using ALC262"

head -n 1 /proc/asound/card0/codec*
==> /proc/asound/card0/codec#0 <==
Codec: Realtek ALC262

==> /proc/asound/card0/codec#1 <==
Codec: Conexant ID 2c06

I changed "options snd-hda-intel model=vaio" to "options snd-hda-intel model=auto" in both /etc/modprobe.d/modprobe.conf and /etc/modprobe.d/sound (whcih should be renamed to sound.conf)

Re: alsa no sound

I don't get the point -  what you did exactly and if it was successful?
