Can I assume that the guide at SDB:Audio troubleshooting - openSUSE applies to OpenSuse 11.4?Thanks.

It does, BUT since Pulse Audio is more common place, there are additional things one can try that are NOT covered by that guide.

Specifically I recommend users install ‘pavucontrol’ and use that to help tune their audio in openSUSE-11.4.

Also, that guide may not solve a user’s problem if they have more than one sound device.
