No, I haven’t tried to work out what happens if multiple audio sources fight it out… just use one at a time…
I am using ONLY analog input for my Phonak TV streamer, works really well. My setup is a bit more complicated though… I do use my TV Toslink output, its gets converted to analog, goes through a small amplifier and is sent to a dual Bluetooth transmitter. One Bluetooth signal goes to my wife’s Bose shoulder speakers (her hearing isn’t great either but she wants no HAs). The other Bluetooth signal goes to a receiver whose output is split (the spin), with one signal going to a standard amplifier/speakers and another signal going to a simple volume knob next to my chair, which then sends audio to the TV streamer.
Yes, ridiculously complex, due to different household members’ preferences…
