Restarting Sound Server in Kubuntu


If occasionally your sound stops working, you can try to restart the sound server:

sudo /etc/init.d/alsa-utils restart

If this doesn’t work, try to kill the processes that block it:

1) Identify them:

lsof | grep pcm

example output: esd 5080 name 70u CHR 116,6 13639 /dev/snd/pcmC0D0p

2) kill ’em:

kill -9 5080

3) restart alsa:

sudo /etc/init.d/alsa-utils restart

That should do the trick. Thanks to the person who posted it here.

    I read the folling link: Thats right but what can I do, if the soundserver in kubuntu dont work, when there are multiple singnals? (for example: i try to play star craft 2 – that works fine, when amarok is not running on startup of the game. but if there is a soundapp runnig, the sound in sc2 does not work. on the other hand the systems sounds dont work, if star craft 2 is running first. i am sure that is a question of settings. can you give me a advice?
    thank you
