Description of problem:
The kernel/installer correctly detects the via82c686 sound chip in my AOpen
AK73Pro(A) motherboard, but produces a very poor sound quality.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. play an MP3 with xmms for example
Actual Results: Very poor sound quality. It sounds like the normal music
with added to it a very distorted high pitched version.
Expected Results: Reasonable quality sound.
This is a regression from RedHat 7.1. With the 2.4.2-2RedHat kernel the
sound is good, but I started to have the same problems after upgrading to a
stock 2.4.5 kernel.
The ALSA sound drivers (tried version 0.5.11) generate an acceptable sound
quality with the same setup other wise. (Tried only with Rosswel2 and OSS
*** Bug 53630 has been marked as a duplicate of this bug. ***
After upgrading to RH 7.3 (kernel 2.4.18-3) the problem disappeared, so I guess
this report can be closed.
