MP 7,1 Strange Audio & Youtube issue

[dubaimac]

My audio setup is unorthodox, I have a usb c cable to a Fiio K3 with optical out to an HDMI adaptor into a Sonos Beam under my display. Audio and YouTube work fine from a reboot. At some point later, roughly 24 hours I can no longer play YouTube videos in safari ( circle spins and a message you may need to reboot your machine) nor can I play WhatsApp audio messages. This is the same across safari and chrome, midi is set to 2 ch 32 bit 48kHz. I don't hear any audio with settings any higher than that. I can't seem to recreate the point at which it doesn't work. Any ideas on any resets or settings I could try and see if it resolves it? Thanks in advance.

This really sounds like a word clock kind of issue from a DA. Used to experience similar with a ProTools studio setup in the G4/G5 days unless they were rebooted daily or shut down at night. Adding a master sync generator into the rack solved all the issues. One of the rack converters basically needed it.
