Is that roundtrip delay, or input/output separately ? What is strange that since most audio devices use the same clock for capture and playback there is no good reason why each of them should be handled separately - for each N samples you get you need to send N samples as well. But of course in USB there will be two separate endpoints... -- FA _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
