Hi @paul_chiu ----- Thank you very much for all of your feedback and your provided screen grab. This information is very appreciated, especially while trying to troubleshoot issues. Some thoughts on your most recent report:
I’d like to get a better understanding of your audio settings in roon. Can you please provide screenshots, based on the examples shown here, as this will help to further eliminate variables that may be causing the issue you’re experiencing.
In regard to trying to playback DSD512 content, roon does not currently support DSD512 content and that is why you are experiencing “just pops and noise” on your Macs. While there is no firm timeline set in place, DSD512 playback is an eventual functionality goal down the line.
