I have a zip with convolution files for all frequencies up to 384. They all work fine.
When I enabled up Sample Rate conversion, MAX or MAX Pov 2, I had nasty garbage in the loudspeakers.
I also had Volume leveling enabled.
I’m using another Nuc i3 with Rock as player. The Audio-GD R7HE21 is connected through USB.
I could not test the 384 khz but I trust the maker of convolution files.
I think I might have an idea: The Amanero in the R7HE21 has a Linux firmware in it and it might - as I recall from Daphile - that it says 768 khz as maximum rate, which is obviously wrong.
I’m not saying it is the root cause BUT Roon could display which is the frequency rate for the MAX and MAX Pov 2. In such case, it could ring a bell
Since my system has not headphone output, I fear to make another tries.
Such error sent in loudspeaker could harm my drivers for good. This old Linn speaker has too much value for me.
Do you know if Roon provides some protection by checking the output buffer to detect harmful data that could be sent to the speakers ?
The headroom may stop it clipping that’s why its in the dsp section.
What you could do is have zero volume but turn the clipping indicator on to see if it is clipping.
The issue is that the Amanero reports 768 kHz insfeead of 384 kHz.
Roon team should creatre a profile for AudioGD Dac and limit the MAX rate to 384 khz.
If someone of the Roon team reads this, many thanks.
