Well in the pulseaudio driver, snd_pcm_delay() will typically *not* return 0 because it will include e.g. network latency. Therefore the wine code which *expects* it to return 0 (e.g. waits for it to return 0) does not get the relevant trigger it needs. The fact that the implementation detail is included in the docs means that the belief that this function *will* return 0 in all cases when no samples are left to be played is totally understandable. As you and James have confirmed, the snd_pcm_delay() function should return details about the delay expected. The fact that this is the "difference >> between appl_ptr and hw_ptr" does not seem to be correct in all cases/impelmentations. I'm no alsa expert so forgive me if I'm just "not getting it". :p Col _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
