Translator:
I had no problems for years and then the alsa error popped up.
After rebooting and reconnecting it started working, but only for a week or two. Now it works again, but the problem will definitely come back.

By the way, I found out that the headphone jack does not work at all.

Volumio 3.449
Raspberry Pi 3
DragonFly Black 1.5

Hi,

Are these logs from when your Volumio was working correctly, or when it did not work as expected? These logs seem rather OK. When exactly does the problem occur, as time goes on?

Also the headphone jack is not working since I assume you are using the DragonFly as output.

Hi.

The problem appeared yesterday and I sent the logs today. Maybe that’s why it’s not there. I wasn’t sure how far the logs go.

I switched to headphones and they still didn’t work.

Anyone help?
Because that expert only annoyed me.
