Re: How to unmute the sound?



I have upgraded the dist to 2.6.24-1-686, the problem still exists.

I tried the ways I can do to install the driver successfully, but still has no sound to output.

- I downloaded the latest alsa driver 1.16 and it's compiled successfully, and the alsa-lib alsa-util can be installed without problems, the volume can be ajusted well, mute or unmute ok.
- use "m-a a-i alsa-source" to compile the driver and install it.

But no sound to output.

It's suffering me a lot. I tried to load the module using " modprobe snd-hda-intel model=dell-m44" or "m42", it can't solve the problem. Whenever opening the audio file, it returns the alsa lib error and errors like "no sound card found":
[AO_ALSA] alsa-lib: confmisc.c:768:(parse_card) cannot find card '0'
[AO_ALSA] alsa-lib: conf.c:3513:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

[AO_ALSA] alsa-lib: pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default
[AO_ALSA] Playback open error: No such file or directory
Could not open/initialize audio device -> no sound.

Also the output of "aplay -l" returns the following errors:
aplay: device_list:205: no soundcards found...

But seems the driver has been loaded and sound card can be detected, it's confused.

Here is some relevant info:

Could anybody instruct what could I do to fix the problem?

Thanks a lot!

Hey Michael, I'm not qualified to help solve this problem and can only

here's a link of interest:

there is some interesting discussion of potential problems that might
steer you in the right direction.

...

these (and subsequent errors) say that the hardware has not been
detected properly.

stop installing non-debian stuff or you'll likely not get
help. Totally remove all the non-debian stuff. reinstall the kernel
and see what happens.

BTW, what kernel are you running?

what alsa pakages are installed?

dpkg -l \*alsa\*

Finally, you claim that it suddenly stopped working for no
reason. Well, there must be some reason. Did you upgrade anything?
Install or remove any packages?

I'll leave the stuff below for reference.
