Unfortunately, I can not reopen it, so I'm posting a new bug report. When using DMIX, Ekiga crashes. This problem was not present with earlier versions of libasound2. I applied all patches from CVS. ====================================================================== ---------------------------------------------------------------------- tiwai - 05-15-06 11:07 ---------------------------------------------------------------------- Are you using the latest HG repo? hg-mirror looks out of sync for a long time. Try HG repo from rsync, or http://hg.alsa-project.org/alsa-lib. The fix is SHA1 ID: 8c310c3277b78a6c53af86939fb5dd6a7db509ea. ---------------------------------------------------------------------- dsandras - 05-15-06 22:33 ---------------------------------------------------------------------- I applied this patch: http://hg.alsa-project.org/alsa-lib?cs=8c310c3277b7 And it solves the problem. However, using the "default" device (and thus implicitely dmix) gives a very bad result with Ekiga. If I defined a .asoundrc file like this one : pcm.snd_card { type hw card 0 } pcm.dmixer { type dmix ipc_key 1024 slave.pcm "snd_card" slave { period_size 256 buffer_size 2048 rate 44100 } } pcm.dsnooper { type dsnoop ipc_key 2048 slave.pcm "snd_card" slave { period_size 256 buffer_size 2048 rate 44100 } } pcm.duplex { type asym playback.pcm "dmixer" capture.pcm "dsnooper" } pcm.!default { type plug slave.pcm "duplex" } Then the sound quality becomes correct, except if the machine is loaded. If the machine is loaded, then the latency increases. Is there any sane explanation to that problem? I'm asking because Ekiga users will complain.
