A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2159> ====================================================================== Reported By: nikke Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 2159 Category: PCI - ymfpci Reproducibility: always Severity: minor Priority: normal Status: new Distribution: Debian Kernel Version: 2.6.15 ====================================================================== Date Submitted: 05-24-2006 23:44 CEST Last Modified: 06-17-2006 10:21 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. The reciever just says "unlock" and stays quiet. The only change is booting with different kernels, no other config or hardware is touched, so this must be a driver regression. The card is YMF-754 based, connected with coax spdif to my HK reciever. If you need more info, just tell me and I'll dig it up. ====================================================================== ---------------------------------------------------------------------- nikke - 06-17-06 01:17 ---------------------------------------------------------------------- I tried to do a quick revert of just that patch from 1.0.11, but there was too many conflicts... However, I noticed that the rear-channel-swapping-thingie shows up in the same function that this patch modifies the most. And since AC3 passthrough works in 1.0.9 this suggests that the patch really breaks things that the rear-channel-swap-patch tries to fix... Mimosius: Can you make a patch between stock 1.0.11 and your 1.0.11-with-working-ac3 so I can test too, and other people really can see that it's the mentioned patch that breaks things? ---------------------------------------------------------------------- Raymond - 06-17-06 10:21 ---------------------------------------------------------------------- Which application change those undocumented registers of STAC9708 ? 0:68 = 0000 0:6a = 0000 0:6c = 0000 -0:6e = 0004 +0:6e = 0008 0:70 = 0000 -0:72 = 8000 +0:72 = ffef 0:74 = 0380 0:76 = abba 0:78 = 9381 Are all channels correct when you run speaker-test -c 4 -t wav ?
