Hi Clemens, I already tried this "rear_swap=1" but AC3-passthrough doesn't work, so there must be another bug which breaks it. bugtrack@xxxxxxxxxxxxxxxx schrieb: > The following issue has been RESOLVED. > ====================================================================== > <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2159> > ====================================================================== > Reported By: nikke > Assigned To: Clemens Ladisch > ====================================================================== > Project: ALSA - driver > Issue ID: 2159 > Category: PCI - ymfpci > Reproducibility: always > Severity: minor > Priority: normal > Status: resolved > Distribution: Debian > Kernel Version: 2.6.15 > Resolution: not fixable > Fixed in Version: > ====================================================================== > Date Submitted: 05-24-2006 23:44 CEST > Last Modified: 06-19-2006 13:33 CEST > ====================================================================== > Summary: ac3 passthrough not working on recent versions > Description: > Using the following AC3 passthrough with mplayer works: > Linux 2.4.31 > alsa-driver 1.0.8-7 (debian stable packaged) > > Using Linux 2.6.15 (both with alsa-driver 1.10rc3 that ships with the > kernel and > alsa-driver 1.0.11) it doesn't work.
