Hi all,
first of all sorry for my English. I'm writing from Italy.
I've a raspberry pi 4 connected by usb on my MicroMega MyDac. Even I start reproduction or skip songs on Spotify or my flac, I lost 4/5 second of music. Reproduction start immediately but sound arrives after. What can I do? Should I change connection and buy a hi-fi berry?

If you are familiar with ssh login and can ssh to moOde then run...

Code:
moodeutl -l
and post the output. This collects the start-up log and will be helpful.

If you are unfamiliar with ssh login reply and we can outline the steps needed.

Ok. A friend of mine will explain to me how to do.
Can you think it could be change something if I set the USB (uac2) fix on "on"? This evening I will try. And, for curiosity, I will try to change usb port too.
Thank you

Sorry. Previously I didn't write tha with my previous amp, a Cambridge cxa81 with integrated DAC, all worked perfectly.

Sorry for my "up" on this thread.
I just want to understand if I have to buy a new DAC.
Probably Mydac doesn't work well with Linux.
Thanks
