My sound wont work on ubuntu live persistant it was working earlier but it stopped when i booted into ubuntu persistant again my sound card is a creative soundblaster i have not used ubuntu for too long and am not too good with terminal so plz walk me through it.

There are several sound blaster cards around. There is also good support for those cards. Odds are your card was detected when you installed. If it was detected, then the correct drivers will be loaded. If they are, the first thing to try is bring up a mixer. I know it is buntu you have installed, so look for a mixer in the Multimedia folder. Open it up, make sure the volume is turned up, and nothing is muted.

Post back, we'll go from there if it doesn't work...If it does, please let us know.

any update yet?

I tried that but it doesn't seem to work. Btw I have ubuntu 9.04

I tested it and when I run live mode it works but in persistent it doesn't.

Would you open a konsole and run these commands and post the results.

'lspci' ( without the quotes ). This will list the devices on your PCI bus. Usually the sound card is there.

'/sbin/lsmod | grep snd' or 'sudo lsmod | grep snd' This will list all modules with snd in the name. Alsa modules have snd in the name.

This is a link to some very good problem determination for sound on Ubuntu.
