Has been working fine for the last many months without issue. Suddenly now no audio devices are detected by roon, not even the onboard audio.
Have read through a number of similar threads but nothing concrete seems to have fixed this issue.
It appears to have happened after the last roon updated was applied (but could also have been a windows update around the same time.
So we can gain some additional insight into what you may be experiencing may I ask that you please verify the following:
Since noticing this behavior have you tried power cycling your Core machine?
Do you have any active antivirus or firewall on the Core machine? If so, please try disabling them and see if you notice any changes upon doing so.
If neither of the above yields positive results, I’d like to recommend a test. If you have another machine that you can run as a Core, install Roon there temporarily and try to use the iFi nano & Parasound Halo. Do you experience the same behavior on the other machine?
