USB DAC can't be selected in USBridge dietpi-config


Recommended Posts

USB DAC can't be selected in dietpi-config in USBridge. I have set it to HDMI, USB 1.1 etc. and back to USB-DAC but did not help.
DAC is Benchmark DAC3. I have checked that it runs in USB2 mode and restarted it.

Worked perfectly before. Issue appeared after disconnecting USBridge from power. It happens on both AC and DC.

I clean-installed latest dietpi on USBridge EMMC card:

DietPi v6.24.1 : 09:49 - Sat 25/05/19
─────────────────────────────────────────────────────

Device model : Sparky SBC (armv7l)
aplay -l results:

Also followed suggestions on https://dietpi.com/phpbb/viewtopic.php?t=2483. Received error:

Have also updated USB DAC drivers according to https://github.com/MichaIng/DietPi/issues/2610.

 

The issue happened before I reinstalled. I reinstalled in an effort to resolve it.

No other DAC available, I'm afraid.

 

My USBridge was purchased from Allo on Apr 18, 2018 (so just about a month out of warranty...).

 

Thanks for any help.
