[LAU] Hardware Soundcard - MOTU 624 AVB Working with Gnu/Linux - Debian 8.7

[georgnk]

Hello, that's very interesting.

I just gave a try a motu 624 with ubuntu lowlatency kernel, but also with a
generic kernel too.

I have the following problem:
Once I test tone with a pure sinewave (easy and reliable way to test a
sound),after a few
seconds periodic clicks are quite audible. Actually these clicks are present
with any kind of sound,
just more difficult to track if the sound is not a pure sinewave.
Did you test your sound using a pure tone in debian?
Do you have the same issue? I tried different workarounds but the clicks are
still there. For sure isnot a jack issue,because using alsa directly I had
the same problem.
Any feedback appreciated from anyone who tried the new Motu products with
linux. 
Thanks a lot!
