My audio interface's (IK Multimedia Axe I/O) reported latency constantly changes.
I've tested using the RTL utility, reaper's reainsert, as well as just recording a kick sample from the input to output of the interface and checking the difference in samples on the timeline in reaper. And with these individual tests there can be a difference of up to 80 samples the next time I run it.
This is all usually at 48kHz sample rate and 64 buffer size. So that 80 sample difference translates to a difference of over 1.5 ms latency.
Is this normal? If not does anyone know what is the issue?
