[SOLVED] Sound issue: HDA ATT SB ALC888 Analog does not work

Ztcoracat · 05-09-2014, 10:07 PM

Hi:

I have had sound all week since I installed Slackware.
The only thing I changed yesterday was my default runlevel from 3 to 4.

Today when I turned my system on I don't have any sound.
I opened the "alsamixer" and raised up the pcm and the master and unmuted all
of the columns.

The system is giving me 2 messages and they are:

Code:

The audio playback device HDA ATT SB (ALC888 Analog) does not work.
Falling back to default.

When I did a sound test I didn't hear anything. Than saw this message-

Code:

Your soundcard is configured properly you have the correct output plugin selected. No other problem is blocking the soundcard.

Code:

bash-4.3$ aplay -l
aplay: device_list:268: no soundcards found...
bash-4.3$ lsmod | grep snd
snd_hda_codec_hdmi     26843  1

soundcore               4318  1 snd
bash-4.3$

How can I fix this?

I found a Arch WiKi page that talked about looking in the /etc/group and adding the already esisting user to the audio group.
Well my browser crashed and I lost the page.

After reading several Slackware, Debian WiKi and Arch WiKi's I was pretty sure that somehow I didn't belong to the audio group.

Code:

usermod -G audio username

Logged out and than logged back in.
I now have sound.

Does anyone know why (if) changing the runlevel effected the sound?
Or effected the user from having audio privileges?
