But I couldn't use tsched mode actually due to rejecting by pulseaudio. But I just couldn't understand why rejected on non-mmap mode.
http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/tests/alsa-time-test.c Do your sound card work with fillrate less than period size ? http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/src/modules/alsa-util.c?id=045c1d602dcba57868845ba3270510593c39480f + if (!_use_mmap) + _use_tsched = FALSE; + You need to ask the author since it was there since gitch free mode
