Help requested please, @Dan_Knight and @rahulkc_s or any other of the friendly peeps here.

I have sent a bug report, reference code: 95673cb8-1092-4fda-a268-dc7ed4921cab

Issue: USB DAC can’t be selected in dietpi-config. I have set it to other options and back to USB-DAC but did not help.

Hardware is USBridge. 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.

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:

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

Thank you for any help.

You might get a quicker response on the DietPi forum. Worth a try, I’m not sure if Dan Knight visits here that often, any more.

Seems you have a point @xxx. Thanks for the advice.

Actually I have no idea why my post was removed from the USBridge thread, where it’s more likely to get a reply.
