My sound card is made by SigmaTel, and I can’t find driver for that.It seems that ALSA doesn’t support my sound card. Anyone can help me?
Why do you say that? I do not see SignaTel listed on the linux audio incompatibility list: Audio incompatibility list for Linux
Did you try working your way through the audio troubleshooting guide for Linux? [SDB:AudioTroubleshooting - openSUSE](http://en.opensuse.org /SDB:AudioTroubleshooting)
Thanks.The problem has been solved.It woks well now.
