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 14:25 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 - 06-17-06 11:02 ---------------------------------------------------------------------- Mimosius There is a patch which supposed to fix AC3 output http://hg-mirror.alsa-project.org/alsa-kernel?cmd=changeset;node=fac92b1b0699;style=gitweb Do this patch fix the problem ? However there is another patch which add an module parameter MODULE_PARM_DESC(rear_swap, "Swap rear channels (must be enabled for correct IEC958 (S/PDIF)) output"); http://hg-mirror.alsa-project.org/alsa-kernel?cmd=changeset;node=2e21f4940a0f;style=gitweb ---------------------------------------------------------------------- Raymond - 06-17-06 14:25 ---------------------------------------------------------------------- Are you sure that your patch in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1447 does not break AC3 pass through ? It seem that there are 3 sources for SPDIF out 1) AC3 2) Digital Mixer 3) SPDIF in 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 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
