I’m having noticeable distortion while streaming via Bluetooth from a MacBook to my new DX7 Pro DAC using the Audirvana player. See the attached files for FR at 1 khz via USB (no distortion) and BT (obvious distortion). The distortion is basically the same frequencies (not harmonic) when tested at other frequencies. I also don’t have this problem via Bluetooth using YouTube - only Audirvana. I have also tried turning off my Wi-Fi router and Wi-Fi on my laptop: No change. I have the latest Audirvana 3.5.24 (3554). It’s upsampling 16/44.1 to 24/48 and I have no options to change it. Thanks for your ideas.

Did you try changing the codec?
