Odroid C2 and USB Sound Blaster SBX support

Hello
I just flash my odroid C2 with Coreelec 9.0.1.
I love it !!

I have no problem with sound on HDMI.
But on USB …
I connect a USB sound blaster SBX and I have a terrible noise.
I can hear the sound of the player but I have on top of it some regular “plop” every 0.2 s roughly.

I have setup an SHH connection … but I am a bit lost on where to look at what to run.
I just run aplay -L

CoreELEC:/ # aplay -L

The same problems with asynchronous USB 2.0 dac. This problem is on all versions, starting with LibreELEC

Hello,
Is there a workaround?
Something to configure to solve this issue?
I was able to use this sound card with a Raspberry PI + libreelec
THX

Hello,
For information I solve my problem using the USB on the go and by powering my C2 from the power jack.
Thx
