Agreed. This is what I was trying to say so I apologise that it was not clear.
If you have different stories, please show reasoning from enough facts, at first. Not from your opinion or memories.
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
