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: Code:
$ lsmod Code:
# lspci Code:
# aplay -l Code:
# lspci -v | grep -i audio 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?
|
I have asound.state (see below) in /etc, but no asound.conf.
Code:
state.NVidia { Code:
pcm.skype { |
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 |
I tried both as a simple user and root, but still no sound...
Code:
$ aplay -D hw:0,0 /usr/share/sounds/alsa/Noise.wav Code:
$ aplay -D hw:0,1 /usr/share/sounds/alsa/Noise.wav |
What happens if you try the following commands? Do you get sound with either of them?
Code:
aplay -D plughw:0,0 /usr/share/sounds/alsa/Noise.wav http://docs.slackware.com/howtos:har...s_on_slackware http://docs.slackware.com/howtos:har..._snd-hda-intel |
Crap, I meant to do plughw. Thanks for the correction, allend.

@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 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.

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