Hi,

I believe it is something with new kernel.

Hi,

We did have an issue with firmware, however, this is now resolved. Lets apply the kernel again:

/DietPi/dietpi/func/dietpi-set_hardware kernel dietpi_rpi

For the USB DAC, lets re-apply the sound card option:
dietpi-config > Audio options > Sound card > USB DAC

Reboot system and let us know if problems persist.

After applying new kernel, everything is now working as expected. Thanks!
