ALSA ALC660 problem

Hi! I've got tons of sound problems on my Asus W5F laptop. Arch setup went clear, and after that i had no PCM or Master controls in alsamixer. After upgrading Alsa 1.0.15 i finally got sound and PCM control , but i can't modify the value - it's always at 100%. if I run /etc/rc.d/alsa restart i get the following:

:: Saving ALSA Levels                                                    [DONE] 
:: Restoring ALSA Levels                                                 [BUSY] 
/usr/sbin/alsactl: set_control:1157: Cannot write control '2:0:0:PCM Playback Volume:0' : Operation not permitted
                                                                         [FAIL]

my kernel is 2.6.23-ARCH
i would be very happy to get some comments on this issue:)

Re: ALSA ALC660 problem

What do the following commands result in?

$ amixer set Master,0 74%,74% unmute
$ amixer set PCM,0 80%,80% unmute
$ su
# alsactl store

Re: ALSA ALC660 problem

Did you try to install the latest version of ALSA from sources? I had such output after upgrading to 1.0.15 version...

Re: ALSA ALC660 problem

I have these two packages installed:
extra/alsa-utils 1.0.15-2
extra/alsa-lib 1.0.15-1

I did not compile them, they were installed via pacman.

Re: ALSA ALC660 problem

i've solved all problems with the damn ALC660 this way.

I added the following to /etc/modprobe.conf:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-card-0 model=3stack-660

and set

FILES=/etc/modprobe.conf

in
/etc/mkinitcpio.conf, and after that i've run

mkinitcpio -p kernel26

under root and after a reboot i got perfectly working sound

Re: ALSA ALC660 problem

Good job, this also fixed my issue, I am able to restart alsa now -- /etc/rc.d/alsa restart

I added the following to /etc/modprobe.conf

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=ref
options snd-hda-intel index=0

edit: removed unrelated question

Re: ALSA ALC660 problem

I also had this issue. I have followed the wiki section:
http://wiki.archlinux.org/index.php/ALS … CM_channel
After removing modules snd-mixer-oss and snd-pcm-oss (although the wiki advises to keep the latter) I was able to somewhat control PCM volue and to save and restore levels
