Sending timestamps derived from a fixed interval did not provide reliable audio output from these devices in general. This was observed with real hardware and tangentially, the hardware did not send SPH timestamps with a fixed interval either. At 48 kHz for example, deviations from a difference of 512 were routinely observed in both directions even with official drivers on vendor-supported OSes. Over and out. jonathan _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
