Hi Chris,
 
thanks for your response.
 
I don't think it's an OpenAL-Problem, because I don't have the devices
any more, also when using aplay / speaker-test etc,
but since here are lots of sound specialists in the mailing list, I
thought I could get help here.
 
Yesterday I recognized it's not just PCM.rear missing, but also the rear
speakers also don't play any sound in surround-Mode.
To be application-independent I tried this with following command (
trying surround40 surround51,surround71, ...):
 
speaker-test -c 4 -twav -Dplug:surround40
 
on my new Shuttle SX58H7. 
First try was with Debian Lenny, second try with a Live Ubuntu 9.10 , 
I have problems with both, I only get sound out of the front speakers (
telling "front-left" and "front-right" in the speaker-test example)
 
It's not a problem of the speakers. Parallel to my new Shuttle SX58H7, I
also have a Shuttle SP35P2 ( with installed Debian Etch) 
where I can get surround Sound ( and also have the PCM.rear listed when
calling "aplay -L"
 
Does anyone have the same problems with surround sound on new linuxes?
 
Best regards
Thomas
