How reproducible:

Steps to Reproduce:
1. play a audio file

Actual Results:  audio file is played but no sound is heard.

Expected Results:  sound should be heared.

PS: I also added a onboard MPU in the BIOS. Maybe this also changed some things. Fact is, the KT400 is not well supported by the new kernels, many people say this.

Comment 1 Dave Jones 2005-07-15 20:17:54 UTC
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.
