Hello.
I am away from my computer with the MOTU 624 AVB for the holidays. I'll
make a try when i'll be back.
But i've just checked the firmware pages of MOTU's web site and :
v1.3.2+520 (Release Date 2017-12-13)
A new one as been added few days ago. I've never tried this one.
Is the the firmware you running your card with ?
The change log says :
Added Bios menu
Hmm i'm really wonder what it does, and if it break anything with
Gnu/Linux Os.
Cheers !

Hello thank you for the reply.
The clicks are periodic.well,not strictly periodic but almost every two
seconds. I have tried your suggestions but didn't change something.
What I have also discovered is that the clicks are not passing through
my
software. Testing a sine wave and using a spectrum analysis in real
time,
sndpeek, clicks don't show up there. It seems they are coming directly
to my
monitors (headphones)
Thanks a lot

If these are random clicks, that sounds like sync issues. Some things
to
try:
- set pulse default and alternate sample rate to 48000
- turn off HDA audio either in bios or in pulse:
pactl unload-module module-udev-detect
pactl unload-module module-alsa-card
(note that if pulse can see any audio card directly,
it may choose to sync from that one even if you are
not using it)
- try different sample rates, in particular both 44100 and
48000. It may be that alsa is under the impression
it can set sample rate when that is not the case.
I have not seen in this thread any meantion of the web interface that
the
motu AVB series interfaces normally have, so I am guessing this is not
one
of these boxes. Motu's support in the past with Linux has be
notoriously
bad until the AVB series, so you may have something that will not work
with Linux properly... as in, it is USB2.0 compliant so far as sound
transfer is concerned, but expects a provided blob to do device setup.
The
AVB series uses a web based setup tool that is OS agnostic.
