Finding the correct audio driver


I think I might not have the correct audio driver installed, the sound is abit scratchy, but it does play, how do I check if I have the correct one?

I have some Realtek HD chip (appeared as one in windows atleast)


O yeah, aplay -l

lasse@linux-vu9d:~> aplay -l

By default, almost all Linux systems use the alsa audio driver. That is the driver most users should be using.

Please read up on the openSUSE sound concepts:
Sound-concepts - openSUSE

Most the time, when a user’s sound is scratchy, it is because they are over driving the alsa sound driver. The solution typically is to go to YaST > Hardware > Sound > Other > Volume and move the volume controls UP there, and then close that, and go to one’s mixer, and move DOWN the controls for Master Volume and for PCM.

Hmm, I went to Yast, turned everything up like you said, closed it.

Then I rightclicked the little speaker icon down in the systemtray, drew the volumebars to 0, system tray icon went away, now no sound at all.

Yesterday I’m uninstalled my pulseaudio packages because scratchy sound. Now I can watch YouTube and vlc, listen to amarok at the same time and no corrupted sound. (Usually I’m not doing all 3 things at the same time - it was just a test :))

Who stated anything about moving the volume bars to 0 ??

Just move them down until you remove any distortion.
