Problém so zvukom cez optický výstup

[Miško]

Ahojte,
Som len obycajny lama uzivatel.
Mam Ubuntu 10.04. Zostava: Notebook Acer TravelMate 4600

Je to pre mna super system. Vsetko nadherne faka od 1. instalacie. Az na jednu malickost.
 Na zvukovke vyuzivam aj opticky vystup do receivera. (cez klasicky JACK alebo zo zadu z docku cez TOSLINK konektor)
Vo win XP mi hra bezproblemovo.
No v UBUNTU to nemozem rozbehnut. Skusal som v nadstaveniach zvuku sa da nadstavit:
"DIGITAL STEREO DUPLEX (IEC958)"  Aj prestane vtedy hrat zvuk z analogu ale digital na receivery nic...
Skusal som aj vo VLC zaskrtnut vystup SPDIF ale stale nic....

lspci: Ak by na niekomu pomohlo
