A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1445> ====================================================================== Reported By: FishB8 Assigned To: ====================================================================== Project: ALSA - plugins Issue ID: 1445 Category: PCM - jack Reproducibility: always Severity: feature Priority: normal Status: new ====================================================================== Date Submitted: 09-23-2005 17:23 CEST Last Modified: 06-06-2006 11:20 CEST ====================================================================== Summary: jackplug and oss Description: I've tried setting up an asound.conf with a config for pcm.dsp0 so that I can use aoss. No big deal. But then I thought it would be cool to set the slave to pcm.jack. That way I could use aoss to route oss to jack using alsa instead of some of the hacks out there that only work half the time. No dice. It doesn't work. (Or at least I couldn't get it to work) Am I not understanding how to do this correctly, or is this just not possible the way things currently work? ====================================================================== ---------------------------------------------------------------------- FishB8 - 09-25-05 21:37 ---------------------------------------------------------------------- The applications I try to run work fine when the dsp0 slave.pcm is set to something like dmixer, but when I try assigning it to either jack or jackplug, (and the jack daemon is running) the applications will start up fine, but when I try to start playback they either segfault or do nothing. Alsa apps have no problem with the jack plugin. For instance if I change pcm.!default to jackplug, alsa apps will route their IO to jack ports without any problem. Here's my current config: pcm.!default { type plug slave.pcm "dmixer" } ctl.!default { type hw card 0 } #Dmixer pcm.dmixer { type dmix ipc_key 1024 slave { pcm "hw:0,0" period_size 1024 buffer_size 8192 rate 44100 } bindings { 0 0 1 1 } } #OSS to Dmixer pcm.dsp0 { type plug slave.pcm "dmixer" } #JackPlug pcm.jackplug { type plug slave.pcm "jack" } pcm.jack { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } ---------------------------------------------------------------------- Raymond - 06-06-06 11:20 ---------------------------------------------------------------------- Your pcm.dsp0 has nothing to do with OSS, it just a customised form of dmix. With jack daemon is running, if your sound card does not support hardware mixing, all application have to used jack interface since jackd already used hw:0,0 Issue History Date Modified Username Field Change ====================================================================== 09-23-05 17:23 FishB8 New Issue 09-24-05 16:58 b0ef Note Added: 0006371 09-25-05 21:37 FishB8 Note Added: 0006388 06-06-06 11:20 Raymond Note Added: 0010073 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
