The updated kernel will be patch in the v149 update:
However, you can apply the new kernel now, with 384KHz support, by running the following commands:
I’m seeing odd behavior with this option on my IQaudIO DAC+ hat. For some reason, the 352.8 kHz sampling frequency is disabled even thoug 384kHz reports full functionality.
This is especially odd, because my HifiBerry DAC+ reports full functionality at all sampling rates up to 384 kHz. Both of these DACs use the same PCM5122 chip as the Allo Boss.
I believe the non-DietPi 384KHz kernel we offered previously, may of had tweaks to specific DAC drivers, enabling 352.8KHz.
Ah yes, you can see the available sample rate for PCM5122. Doesn’t look like 352.8KHz is supported by this driver currently, at least without some modification:
