Sorry for bothering the list again, but I have major problems with the
surround 5.1 sound. I have manually compiled/installed th latest
alsa-1.0.14 drivers but nothing improved. I am using Ubuntu 7.04 and my
soundcard is the Hercules Fortissimo III. This is, as far as I know by
reading on Internet, supported by the module snd-cs46xx in ALSA. I have
enabled the surround sound by creating the following .asoundrc file.
The problem is that sound pauses whenever I try to do something "heavy"
such as opening a new firefox window or generally another app. Also,
there are delays and echo between the front and the rear speakers from
time to time. I think that the problem is that, this alsa setup(meaning
surround5.1 and the specific soundcard) places a heavy load on the cpu.
There are 99% cpu usage times when the only thing active is a player
playing a "normal bitrate" mp3. When I delete the .asoundrc file and I
switch to default stereo sound using only the 2 front speakers the
Can anyone suggest anything about this?
Thanks in Advance
