Description of problem:
I am running on an Athlon machine. My sound card is the sound blaster live 5.1.
When I upgraded from rh 7.2 to 7.3, I began to experience problems with the
sound craking up / breaking up. It sounds terrible. Hope someone can help
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. setup rh 7.2
2. upgrae to 7.3
3. run any sound application
Actual Results: it sounds terrible! I don't know if the upgrade installation
as opposed to a clean installation changes anything.
Expected Results: its a great sound card - it should sound good
I also got the same symptoms. High volumes of PCM (on digital CD it is fine)
(85% and up) give a large amount of distortion. This didn't used to happen in
7.2 (I'm using 7.3 with 2.4.18-4). I noticed that for the same PCM volume,
7.3 gives louder sound than 7.2 and than other inputs (digital in, ...). Also
the volume in the rear speakers is much lower than the front speakers. In
short, the old driver sounded better.
PS: My card is also a SB Live! 5.1
Get emu-tools from http://sourceforge.net/projects/emu10k1 and do "emu-config
-B off" (-B, --boost=on/off Turn on or off a 12dB boost on analog front
output), this makes it sound just like in 7.2.
