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 16:10 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 15:16 ---------------------------------------------------------------------- Being less tired than yesterday, I tried the following: Using Linux 2.6.8: ALSA 1.0.9b AC3 works, 1.0.10 AC3 does NOT work. When reverting the "ymfpci: add per-voice volume controls" patch from 1.0.10 AC3 passthrough started to work. Since 1.0.10 compiles on Linux 2.6.15 I have been able to verify that reverting said patch makes AC3 work on my normal setup too. To conclude, I agree that "ymfpci: add per-voice volume controls" breaks AC3 passthrough. ---------------------------------------------------------------------- Raymond - 06-17-06 16:10 ---------------------------------------------------------------------- It seem that is a bug related to "ymfpci: add per-voice volume controls" It should assign kctl->private_value = substream in snd_ymfpci_playback_open() instead of snd_ymfpci_mixer() I had upload a small program (iface_pcm.c) to test this feature for au88x0 in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1835 Issue History Date Modified Username Field Change ====================================================================== 05-24-06 23:44 nikke New Issue 05-24-06 23:44 nikke Distribution => Debian 05-24-06 23:44 nikke Kernel Version => 2.6.15 05-24-06 23:47 nikke Issue Monitored: nikke 06-02-06 04:23 Raymond Note Added: 0010045 06-02-06 04:25 Raymond Note Edited: 0010045 06-12-06 13:14 Mimosius Issue Monitored: Mimosius 06-14-06 22:32 nikke Note Added: 0010216 06-15-06 02:18 Raymond Note Added: 0010221 06-15-06 02:27 Raymond Note Edited: 0010221 06-15-06 11:03 Mimosius Note Added: 0010237 06-15-06 23:43 nikke Note Added: 0010246 06-16-06 13:01 Mimosius Note Added: 0010250 06-16-06 13:16 Mimosius Note Edited: 0010250 06-16-06 13:26 Raymond Note Added: 0010251 06-16-06 13:31 Raymond Note Edited: 0010251 06-16-06 13:37 Mimosius Note Added: 0010252 06-16-06 16:25 Raymond Note Added: 0010255 06-17-06 01:17 nikke Note Added: 0010262 06-17-06 02:43 Raymond Note Edited: 0010251 06-17-06 10:21 Raymond Note Added: 0010266 06-17-06 10:24 Raymond Note Edited: 0010266 06-17-06 11:02 Raymond Note Added: 0010267 06-17-06 14:25 Raymond Note Added: 0010268 06-17-06 15:16 nikke Note Added: 0010269 06-17-06 16:10 Raymond Note Added: 0010270 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
