When streaming from Qobuz with 192 kHz/24 bits, or even when reading files bought on Qobuz with this Hi-Res quality, I have some sizzling, sometimes strong.
My DAC is able to handle such Hi-Res quality files (the screen indicates 192 kHz is recognized).
My Qobuz subscription is Hi-Res 192 kHz.
As soon as I change the frequency target to 96 kHZ in Audirvana, there is no more sizzling.
Please see attached debug info.
What could be done to avoid this ?
