I dont know if you received an answer to your post, I wlll try to help you out. I had a number of posts recently about hdmi dropping audio from the B2 to two separate amps, and had seemed that no matter
what sequence of turning on/off the tv/amp the audio would certainly drop out. I have since gone back to the optical connection and that has not dropped audio once. If you choose the hdmi option.............
1)hdmi out from the B2 to hdmi in on your amp. Not knowing your amp model, make sure you have it set to recieive the hdmi signal.
2) Toggle on the 'hdmi audio out to tv' on the B2. If you have your tv connected to the amp with any type of video pass through, your should still see 'whats playing'. If, by chance, you dont hear sound at first,
try to re-toggle the 'audio to tv' off, then on again.
Happy listening, if you have any other questions about the hdmi or optical connections, put up a post.
