USB Audio Stops Randomly and is lost

Mdc · April 16, 2021, 2:12pm

I am using the latest version of Volumio on RPi 4B connected via ethernet and outputting via USB to SMSL SU-9 DAC. DAC has latest firmware.
I am playing Tidal Hifi and Masters all the time. No Local Music.
Buffer values are %10 and 2Mb (Defaults)
Queue is not long (<20 songs)

Some time after music has started (looks random from 10 minutes to an hour mostly) the audio is lost and no sound comes out from the DAC. DAC says “No Signal”
GUI looks like music is playing but trying to skip song or playing another does nothing and there is no sound.

Restarting the DAC does not resolve problem.
Unplugging and replugging USB cable does not resolve problem.
Changing output device to Headphones, saving, then changing output device to - SMSL USB AUDIO again resolves problem.
Rebooting RPi Resolves problem.

Any help or pointers are apprecieted.

Well after trying many things including different usb ports, usb cables, dns settings, disabling plugins and features, buffer settings, power cable and supply, wifi connections I couldn’t find a solution.

But as a workaround I enabled upnp and used mconnect player for accessing tidal and transferring audio using upnp to Volumio. Now I can listen without problems.
Using phone just for control is better but this will do.

As tidal connect is coming to Volumio in days, I can just use it for lossless audio and mqa.

mqa you could only create on max volume.
