Details

I have an XPS m1530 with kdemod4 which used to have sound in the previous kernel version.
but after update to the new kernel I do not have sound anymore.
I have added !snd-pcsp !pcspkr !snd_pcsp in my modules list and @alsa in my daemons list.
But I still do not have sound.
This task depends upon

Reason for closing:  Not a bug
Additional comments about closing:  One of the front channels in kmix was muted, how that happened automatically after the upgrade is still mystery.

make sure you have your channels unmuted and loud in alsamixer
then run speaker-test

I had to run alsamixer to get rid of the last 'mute' on my speakers.. please check that. It is very annoying anyway

I saw the channel levels in kmixer and they are all unmuted and high i do not have alsamixer i just have alsa-libs package.
I never had @alsa in my daemons list either previous to latest kernel update and the sound was working when i had 2.6.27 in testing.
I do not understand how it can work in testing and then mot in core :(

1) install alsa-utils package
2) make sure you're in group 'audio' (run 'groups' to see)
if not - run 'gpasswd -a your_username audio'
(note that you will need to relogin for this to take effect,
so better just run the commands below as root)
3) make sure channels are unmuted in alsamixer ('M' toggles their state)
if it starts and shows card name then drivers are OK
4) run 'aplay /usr/share/sounds/alsa/Front_Center.wav'

if you hear the sound then the problem is somewhere in KDE's sound system.


FTR, it is better to ask for help on forums first before reporting problem as a bug.

I did ask in the forums infact in multiple threads, one of the front channels was muted in kmix and i have requested for the bug to be closed.
Thanks to all of you for the help
