Audio devices GONE after PC reboot. WHY?

My audio devices that were present and operational before a core PC reboot are no longer present. Both PS Audio DAC and Sonos operational and are fully present on my PC network.

Dunno, but there’s this -

I lose my audio devices constantly and I don’t use Tidal. It’s becoming unusable, and now that it doesn’t support Apple Music Lossless which I know is not your fault I doubt I will keep subscribing. I use many audio players on iOS and they can access my Apple Music library as long as they are downloaded files so I don’t see why you can’t but anyway.

This has me back up with my library cd’s at least. Thank you!
