Ordered a Monoprice HTP-1. We'll see if there are any issues with that.
Some documentation of the switches I used with Dante:
GS105PE
GS108PEv3
GS308EPP
TPE-TG84
Those are the Netgear switches I've used and one TRENDnet. None of them worked.
I've also used the dumb device below that only injects PoE power and doesn't perform any switching.
That was used with a Dante Avio adaptor to AES over XLR, and with the adaptor or the JBL set to the master, there was still a ticking sound every several seconds when Dante is enabled.
Troubleshooting further with JBL they confirmed there is an issue even with replaced Dante boards and they have been working on it for over a year now. Source was Spotify connect directly to the JBL unit so no source devices would be the issue.
Harman Issue Number IMS0024523
