board?
usb audio device/ model?
lsusb -t?
reproducable?

Please give us something to work on, guessing is useless :wink:

Board name is already there - BeagleBone Black.
USB DAC - Zhilai Audio H1.

Reproducibility - yes. Last occurrence: after about 40 min of listening to a webradio audio just stopped. The dmesg output was generated after I pressed the play/pause button again in the GUI. There is no such issue when I’m listening from AirPlay source or from NAS.
Thanks for looking into the issue.

Any errors in the logs about usb wifi rather than the DAC (not sure if you’re using wifi or ethernet)?

5

I’m using wired Ethernet, no Wi-Fi.
No USB errors, but it was a comment by michelangelo saying “USB should be on hw:5, not 1”

One more crash after 45 min :frowning:

Which Volumio version are you using,on which hardware?

There are possible issues with latest 2.141 on Pi due to unexpected firmware components in the image: this may impact several hardware components, including supported DACs…

BeagleBone Black, image file volumio-2.129-2017-03-26-bbb

Edit: the issue with the audio stop seems to be related to DHCP renew on the router WAN interface when all the NAT sessions get cleaned.

8

I see almost the same on Raspberry Pi - audio stops when WAN IP gets renewed, but pressing Stop/Play restores the audio.

Edit: audio stop seems to be a known problem, reconnect-webradio-after-24h-provider-break-t6273.html
