Ok, I tried that but unfortunately the given config doesn't work:
I get parsing errors ("slave is not a compound") when trying to run xmms...
Furthermore I don't understand what exactly is the difference
between my config and your's. How can I choose between upmixing
and "real" surround sound?
If I play a dvd only upmixing works, without using my custom .asoundrc
I only get sound out of the front speakers... surround51 doensn't work.
To all of the readers:
Does anybody else know how to distinguish between upmixing stereo input
and real surround sound and to take this into account in the
alsa .asoundrc?
Perhaps someone knows how to fix the surround51 alsa script to work
with the S32_LE format of the ICE1724 chip?
Thanks!
