I see. Thank you for the explanation. That might explain Lennart Poettering's remark at: http://mail.gnome.org/archives/desktop-devel-list/2007-October/msg00136.html "...Gustavo brought up the issue that PA "hogs" the sound device. Sure we do. The idea is having everything go through PA, so that we can treat everything the same. However, since there are some APIs that are notoriously hard to virtualize (e.g. OSS with mmap) and some areas where you don't want the extra context-switching PA adds (pro audio, for now)..." > The response from Lennart Poettering main PulseAudio developer (in > this post he explains better than me the scope of PA): > http://0pointer.de/blog/projects/jeffrey-stedfast.html Thank you for that link. It is very interesting reading and good information from the lead developer of PulseAudio. To me, after reading some of this and other material, it seems that PulseAudio is a noble effort to bring a lot of good things to dealing with audio within a typical desktop computer. However, for those interested specifically in audio applications and associated programs such as jack, Ardour, etc., it may be better--for the present, anyway--to disable or circumvent PulseAudio and rely on the already-working-well combination of jack and alsa. Perhaps with further development PulseAudio will work well with, and not cause any or many issues with, the audio and audio/MIDI applications that we as linux-audio-users spend some considerable time with. :-) Steve _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
