Volumio stops playing after a while - USB DAC (Topping D50s)

Volumio stops playing randomly after some time. I have to restart it again as a workaround, but it’s only a matter of time before it happens again. I’ve been looking at other issues raised in the forum and it seems this is a common and know issue, but without definitive fix so far. All the solutions I tried from other posts are not working (event factory reset).

Here is the error I can see when pressing play after it stopped:
failed to open alsa [alsa], Failed to open Alsa device “hw:5,0”: No such file or directory

Here is my setup:

Raspberry Pi 4 8gb
Volumio version: 2.868 (Experienced the issue with anterior version also)
USB DAC: Topping D50s

I just noticed restarting the DAC works as well. It seems the issue has to do with the USB connection. Maybe a USB driver issue.

I observe the same behavior. Regardless of the model (Allo BOSS-Dac, Hifiberry Dac, Hac2 HD, …)
If I start and run a radio station and come for a few hours or the next day, Volumio is silent. (although it looks like he’s playing normally)
Sometimes it happens after an hour or so …
Stop and start again and Volumio will play normally again until the next one …
The next time he falls silent, I’ll send you a report.

I played my Flacs from my NAS with replay for a long time and there were no stops.
But when the radio is played, there are always stops. Sometimes it takes longer, sometimes less. Now it has stopped after 93 minutes and 55 tracks.
It had belonged to the SwissPop radio station, and the same thing happened with other radio stations.
Apparently the stops only occur with the radio playing?
Start: 08:28:12
Stop: 10:01:17

Hello, I tend to observe the issue less often in latest version.
Also, other difference is I disabled some plugins I used to have:

Logitech Media Server

and

Sqeezelite player

to use my Deezer acount.

So far all the potential root causes as per other tickets too are:

  • USB driver issue (Maybe update your DAC firmware if any)
  • Too large playing list (this should be fixed by now I think)
  • Check that your DAC is not going into sleep mode for some reason
  • Check the radio stream signal is not lost at some point too. When that issue occurs maybe try to switch to another radio channel and see what happens

Additionally you can check my settings screenshots below and see if that works. I hope that helps

I can’t confirm the less frequent error. Volumio often stops playing a selected radio station, e.g. after an hour or less …
All settings are correct, the network connection is good. Playing Flacs from my NAS spells forever without interruption.
Logs are delivered above. I hope this helps to find the problem.
It’s very annoying when the radio suddenly goes silent …! :wink:
