I have a Yamaha RX-V681 receiver connected to my TV. It has various devices connected via HDMI. During the daytime I use a 5.1 speaker setup, but at night I'd like to use headphones instead. This is pretty easy to do with wired headphones, but I'd like to eliminate the headphone cable if possible.
I setup the Yamaha receiver to transmit bluetooth audio to Avantree Aptx bluetooth headphones ( https://www.amazon.com/gp/product/B01A0EAYDI
). This was pretty simple since the receiver has bluetooth transmission builtin. I've found when it works correctly, it is great. However, the audio lags and cuts out sometimes. I've tried a few different headphones over the last two months and have received similar results on all of them, which makes me think the problem is the Yamaha bluetooth transmitter. This leads me to want to try a different bluetooth transmitter.
I've found a few bluetooth transmitters which are known to work well with minimal lag and I can connect them with RCA inputs or a 3.5mm jack. The RX-V681 has Zone2 RCA outputs, but according to the manual it apparently only works for analog input signals - which I'd expect to not work with my HDMI inputs. Alternatively, I could connect a bluetooth transmitter to the headphone output on the amp, but that would require me to get up and plugin/remove the transmitter to turn on/off bluetooth everytime I wanted to switch back to regular speakers. It also has zone2 speaker wire outputs which I'm not using for anything - could I use these in some way for bluetooth transmission?
Anybody have any suggestions on how to get bluetooth headphones working seamlessly with this receiver? One of the reasons I bought this receiver was it had bluetooth transmission built in, so it is pretty frustrating that I'm running into problems with it.
TLDR: How can I hookup an external bluetooth transmitter to my Yamaha RX-V681 which works for both analog and digital sources? Alternatively, how do I make the receiver's builtin bluetooth transmitter not lag/cut out.
