My FBO recently got a brand new SR20 G6. Yesterday, I went for a check-out flight in it and my Lightspeed Zulu was not working properly. Specifically, I could not hear anything, but my CFI heard me just fine. We further confirmed it was not the headset as we tried a Bose A10 and it had the same problem. I also used my headset in another plane and it worked fine. HOWEVER, my CFI, using a Bose A20, was able to work properly when he plugged into the ANR jack (not the normal two prong jacks).
Lastly, we were able to get the headset to work when when put the jacks in only part of the way and held them (obviously, useless for flying, but maybe telling of something).
Any thoughts here?
