Thinkpad T410 : sound issue


Hi all,

I've got a Thinkpad T410 running Slackware 14.1. All is great, but since I switch to the generic kernel, my user account doesn't have any sounds.

Under root, aplay is working great.

If I understood correctly, there is 2 sounds cards on my laptop.

So, how to set the good sound card by default ?

Thank you,

PS : I read http://docs.slackware.com/howtos:har...s_on_slackware


Regards

Did you also switch to runlevel 4 (starting up to a graphical logon)? Because, by default new users aren't assigned to the audio group (needed to access audio devices) unless you manually specify it when you created the user (there was a big screen asking you to press "Up" for the default groups). When you start up in runlevel 3 (straight to the command prompt) you're assigned to various groups by the shell, including the audio group. So, when you run startx, you're still associated with the audio group, so you can access the sound card. If you change your default runlevel to 4, then you're no longer associated with the audio group, so your access is denied.

You can check by running the groups command. It should look similar to the following:

Code:
jbhansen@craven-moorhead:~/scripts$ groups
users lp floppy audio video cdrom plugdev power netdev scanner
If yours only shows users, then you need to add yourself to the other groups. Do the following as root (replacing $USER with your username on the computer:

Code:
usermod -a -G lp,floppy,audio,video,cdrom,plugdev,power,netdev,scanner $USER
