[Solved] Audio works for root, but not any other users

iso · 2010-12-31 20:37:13

I have a dell dimension e521, to which the audio card did not work out of the box. After following some steps [1] I was able to get sound, but only if when I run the file with sudo.

Does anyone have any idea why this is, and what I can do to prevent using sudo?

Thanks for the help

Your user is in the audio group?

iso · 2010-12-31 21:08:27

Good catch. My user is not in the audio group, but for some reason there doesn't seem to be an audio group, so one of the other groups is probably the one that I want to add. the groups that the root user belongs to are: root bin daemon sys adm disk wheel log

I am also having problems adding my user to an additional group.

`usermod -a -G wheel chris` should add the user chris to the wheel group right? For some reason it does nothing.

**UPDATE: after logging out my groups were updated. Unfortunately, after adding all the groups the root user belongs to I am still unable to get any sound.

You installed alsa-utils right? I am pretty sure that is what creates the audio group.

iso · 2010-12-31 21:35:55

yes alsa-utils are installed

Shouldn't it be your user added to the audio group rather than root? Your user would have to be in the wheel group to do sudo by default

Running (as root/sudo)

gpasswd -a chris audio

will add user CHRIS to group AUDIO.

As user, what is the output of

id

. For comparison mine is

[21:52:00] SS4 ~/clementine/build $  id                                                                                                                                                                    
uid=1000(SS4) gid=100(users) groups=100(users),7(lp),10(wheel),91(video),92(audio),93(optical),94(floppy),95(storage),98(power)

edit: have you checked to see if alsamixer has any channels muted?

gpasswd did add the seemingly non-existent audio group to my user and things now work.

Would you care to elaborate on why gpasswd worked when usermod didn't?

Thanks for the help.

You used usermod to add Chris to the Wheel group rather than the Audio group

iso · 2010-12-31 22:26:16

I did previously tried adding my user to the audio group, but it seemed that the group didn't exist.

305 useradd -G audio chris
306 usermod -a -G audio chris
307 sudo usermod -a -G audio chris
315 sudo usermod -a -G audio chris
456 history | grep audio

Thanks again
