So, I've looked into this today and as expected, the device normally operates in implicit feedback mode. After installing a proprietary driver on Mac OS X (that regularily crashed my kernel), the analyzer shows that for every inbound packet, an out packet is sent back with the same amount of data in it. And there are no feedback endpoints.
yeah m-audio can't write software or design hardware we know ;)

There are still the issue of samples dropping.
Tto reproduce it:
- Open Audacity and set it up to be using Jack.
- Click Generate -> Tone -> Ok.
"Normally" you should hear very regular pops...
What surprises me though, is that I can't hear the clicks and pops you guys describe. Instead, I hear a quite annoying distortion for both 44100 and 48000 Hz which I can't explain either. My spontanous guess is that there is a resampler in the chain which compensates the sample drift and notably reduces the audio quality.
eww that's uncool.
Silly question In the mac controlcentre ensure you've turned off/bypassed the reverb/dsp capabilities?
I've previously replicated this with audacity and jack. (at 24bit 96kHz) but when I get home I'll give aplay a go after generating the sine.
I'll see if I can capture it and make some waveform's or something and I've tested my other usb soundcard and it doesn't have the clicking.
Grant.
