Sorry, I didn't check carefully enough. module-combine-sink does enable prebuffering. I'm not sure why. Maybe the prebuffering could be disabled (pass 0 instead of 1 as the prebuf parameter of pa_memblockq_new()). -- Tanu _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
