No sound when playing - Pas de son en écoute

Hi eveyone,
I use Audirvana on my MacBookPro with a SMSL DAC M300. It’s been working all these past days, but today, while the music is played, no sound comes out of the speakers. I guess this is an Audirvana issue because the music can be heard when it’s played with iTunes, Youtube or any other…
Can anybody help ? Thanks in advance.

Bonjour à tous,
J’utilise Audirvana sur mon MacBook avec un DAC SMSL M300. Cela a bien fonctionné ces derniers jours, mais aujourd’hui plus de son. Il y a du son avec iTunes, Youtube, etc. mais pas avec Audirvana. Je n’y comprends rien.
Merci pour votre aide.

Have you tried to disconnect and reconnect the DAC?

Yes, I did. And tried many things too…

Can you paste the debug info here while trying to play to the SMSL DAC.

Try to disable the upsampling.

It is working now.
The volume control was activated. I disactivated it.
Thank you !
