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

[georgnk]

Thank you for the response. I connect my motu using usb 3 ports,but I have
also tried to disable usb 3 functionality from bios.

I mainly connect it via qjackctl. Then I test tone using pure data,440 hz
sinewave. You can also test it using audacity generating a sine wave tone.
If you prefer command tools,maybe you can use libraries like stk toolkit or
Maximilian ,in c++.
I can also select my sound card without qjackctl and Jackd.
Pure data can see my input s and outputs directly. Then I go audio test play
the sine wave , wait a while, I move frequency up and down,clicks start and
never stop.
I use the latest firmware,but I couldn't find a way to downgrade,it says the
old firmware can't be used,its out of date.

Thank you
