Thanks again for all your work on RoPieee.
I am hearing an issue with the Topping D90 MQA DAC when it switches formats from DSD (either native or DoP) to PCM during playback. There is a very short, but loud, crack/pop as the format switch takes place. Once switched the music plays normally.
I tested the DAC with Roon on a windows machine and the issue did not occur.
My workaround for now was to have Roon convert everything to PCM, no issues switching different PCM rates. (tested mix of 44.1 all way up to 352.8k PCM).
I did see that the D90 MQA uses XMOS XU216 usb chip (as opposed to XU208 in D90 model).
Any thoughts ?
