For PCI devices this is usually the same as write_index-read_index, but not for virtual devices like PA, and not even for USB. This is the only way snd_pcm_delay() has any value for synchronization purposes (i.e. syncing video to audio). I think there's simply in invalid assumption made by the WINE devs (or possible even the MS devs who designed the API): they assume that all sound cards are PCI sound cards. Which ain't really true. In short: the transport latency *needs* to be taken into account, there is no way around this. > https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3944 This looks good to me and should also be applied. Could you please post the patch for 3942 and 3944 to the ALSA ml? The truth is that the ALSA devs are very good at ignoring the ALSA BTS. If you want your stuff merged, post it to the ALSA ML, don't bother with the BTS. And thank you very much for your patches!
