Issue with Yamaha receiver

[daninthemix]

I believe the problem is fixed. Yay! I did more digging and found another forum thread that sounded similar.

That thread made me think about my networking situation. It was:

Amp --> Netgear Switch --> ZTE router
PC --> ZTE router

After reading that thread, it's now:

Amp --> Netgear Switch
PC --> Netgear Switch

So both devices on the same switch, rather than having to also go through the router, seems to have fixed the problem.
