Issues Streaming AirPlay Music from M1 iMac to Apple TV 4K (Gen 4, HD & 2021)

Recently upgraded to the M1 iMac and I'm having issues streaming to my Apple TV 4K (latest 2021 model) and Apple TV HD (last Gen). I'm on macOS Big Sur 14.1. I can connect, but the connection frequently drops out. I've tried both resetting to factory defaults and also connecting via Ethernet. Interestingly enough, I have a couple Gen 3 Apple TVs that I use for music due to the optical audio port and a couple AirPort Express units, and those work just fine without dropping out. I can stream without issue from my iOS devices.

My first thought would be wifi interference between boxes and computer, but I'm not sure how viable that suspicion proves if you are switching the two problem appleTVs in place of the ones that don't cause you problems (of course, it is still different hardware). Do you have any bluetooth enabled equipment near these two problem devices? What about headsets or security cameras? Xbox controllers? Analog audio systems? Baby monitor? All potentially use proprietary wireless tech that could interfere.

Hi, thanks for the suggestions. I do have some other devices nearby the Apple TV; however, I'm using an ethernet connection from my router to the Apple TV. My iMac is on wifi, but I'm about 5 meters line-of-sight from my AirPort Extreme and never have a connection issue on that end ("Excellent" - usually ~ -52 dBm). Furthermore, one of my Gen 3 Apple TVs with which I have no issues is in the same location (also on Ethernet).
