828 mk3 hybrid: random glitches OSX 10.11.6 / audio file

Post by rybaz »

Hi there,
I get random glitches, not intentionally reproducible.
Zoomed in looks like some heavy downsampling and bit reduction.
It happens erratically sometimes every 5-15 minutes, though sometimes does not occur for 1-2 hours.
I have done any debugging I could think of. Tried this on
different computers (macbooks pro and mac mini, all running OSX 10.11.6
though), changed USB/FW connection, disabled any WIFI/BT, it runs on
internal/master clock (as no other digital devices connected), latest
drivers/firmware installed.
Tried different DAWs, different Buffersizes etc.
Nothing helps so far. Definitely not CPU utilisation related.
Unfortunately don‘t have any windows machine here to test.

As far as I could test it happens only in the computer interface mode as
a device in the DAW. When used stand alone as ADA converter/mixer the error
has not been observed.

On the same machines I use sometimes RME babyface and fireface UFX with no
issues at all. Also the OSX console and the HALLab does not throw any
reproducible errors, which would occure every time when there is a glitch.

Here comes an audio sample.

Anyone with these experiences and hopefully a solution? Possible driver issue or is the unit a brick now?
