Sound card suddenly not recognized anymore on Slackware 14.1.


I am using Slackware 14.1 (not current), with MATE on a Macbook 5.2 from 2009 (http://www.everymac.com/systems/appl...dia-specs.html), whilst I login with KDM.

As the title suggests, in my MATE session suddenly the audio simply refused to work no matter the application. I then rebooted, shutdown, and went to my KDE session where a dialogue box greeted me, saying that "one or more internal devices have been removed" and listed them as "Capture: HDA NVidia, ALC889A Analog (Default Audio Device)
and "Sortie: HDA NVidia, ALC889A Analog (Default Audio Device). Needless to say, when I log back into MATE, there is no sound.

I do not think that this is a hardware related-issue since Slackware is installed in dual-boot with Mac OS X (via rEFIT and LILO) and there the sound works as usual. This might be related to the drivers. Still, in "sound preferences", HDA-NVIDIA is highlighted ans selected as before this incident.

Here are the basic infos about my system:

I checked this topic here: http://www.linuxquestions.org/questi...rk-4175540579/

but I confirmed that I was already in the audio group by running #usermod -a -G audio lensilvan, which returned nothing, and in my case, no application release any sound.

Do you have an /etc/asound.conf or ~/.asoundrc? Are you trying to use analog or digital sound output?

However, I have ~/.asoundrc with the following contents:
Code:
pcm.skype {
    type route
    slave.pcm "hw:0,0"
    slave.channels 2
    ttable.0.1 4
    ttable.1.0 0
  }
I think I use digital sound output.

What happens if you try the following commands? Do you get sound with either of them?

Code:
aplay -D hw:0,0 /usr/share/sounds/alsa/Noise.wav
aplay -D hw:0,1 /usr/share/sounds/alsa/Noise.wav

I tried both as a simple user and root, but still no sound...

@bassmadrigal - I have just realised my post could have been interpreted as arch. Thanks for not taking offense.

OK, I tried to play the 2 last tracks but still without any sound. The only difference is that I did not receive any error message like the previous tracks.

Code:
$ lsmod | grep snd
snd_hda_codec_realtek    34792  1 
snd_hda_intel          34861  6 
snd_hda_codec         143196  2 snd_hda_codec_realtek,snd_hda_intel
snd_hwdep               6388  1 snd_hda_codec
snd_pcm                76009  2 snd_hda_codec,snd_hda_intel
snd_page_alloc          7098  2 snd_pcm,snd_hda_intel
snd_timer              18614  1 snd_pcm
snd                    58630  18 snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_pcm,snd_hda_codec,snd_hda_intel
soundcore               5354  1 snd
Apparently, the correct driver isn't even being loaded since I use HDA nvidia (see on top), unless I am being wrong.

On alsamixer, I tried to change the card but only 2 choices were available: "Default" and "HDA nvidia". But both of them keep the chipset at Realtek ALC889A and the card at HDA nvidia.

Your 00:08.0 Audio device: NVIDIA Corporation MCP79 High Definition Audio (rev b1) is supported by the hda-snd-intel kernel module, so the driver is correct.

I would be looking at the alsamixer settings. Are your outputs unmuted? Are your levels set high?

At the exception of "Master", all the others are set on mute and I can't unmute them...

Oh, I forgot to read man alsamixer: I thought that to unmute them, I had to use the spacebar. I didn't know (or I forgot) that I simply have to use 'M' for unmuting them...

Needless to say, now the sound works fine. It was simply Alsamixer which switched for no reason to 'mute'.
