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: 06-16-2006 13:37 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. ====================================================================== ---------------------------------------------------------------------- Raymond - 06-16-06 13:31 ---------------------------------------------------------------------- Are you really sure that the patch "ymfpci: add per-voice volume controls" break AC3 passthrough, the purpose of that patch is to implement pcm volume control per substream using the hardware mixing of ymfpci Please note that STAC9708 has no SPDIF control registers, there is no need to compare ac97 registers You should compare those ymfpci register cat /proc/asound/card0/ymfpci iecset ---------------------------------------------------------------------- Mimosius - 06-16-06 13:37 ---------------------------------------------------------------------- Hi Raymond, yes, I'm really sure this patch breaks AC3 passthrough. A comparison of the /proc/asound/card0/ymfpci registers against 1.0.9b (patched up to 1.0.11 without Clemens patch) and 1.0.11 (native) is included in my previous note.
