ARC Issue on this TV :
Yamaha AMP (RX-V371) (ARC activated, default of AV4 for ARC)
HDMI cable from amp's HDMI out to TV's HDMI1 (ARC enabled port)
HMDI Cable from amp's HDMI2 to PVR.
HDMI cable from amp's HDMI3 to AppleTV
ARC configured on TV.
(Note saving amps HDMI1 for future bluray)
Turn TV on, antenna input on tv, AMP is on AV4 input, press simplink, get 'simplink device not found' message. Press home to get smart TV (what I want to send to amp really as dont watch any live TV), press simplink, get same message - 'simplink device not found'.
Now - If I turn on the PVR, change amp to HDMI2 for the PVR input, can see the PVR on the TV screen and THEN press the simplink, the amp changes to AV4 automatically and all is good then.
I can then flip between HDMI2 and AV4 on the amp and flip between the TV output and the PVR input as expected.
It seems that the ARC on the TV will not see the AMP unless it already has something sent from the AMP to it (like the PVR or the AppleTV ).
For example, I am watching a movie now via medai link, sound is coming from the amp all good. However if I turn off the PVR, then sound stops from the AMP.
In summary, TV must have AMP input before ARC works. If you purchased the amp and tv together, and have no other devices to input, as if you just want to output all sound from the TV to the amp, you could not as the amp must have another input going to the TV FIRST before simplink can be configured!
Please dont offer an optical cable solution, yep that would work, but my TV is wall mounted, built a new house and HDMI is run in the wall so just have the one cable (and an ethernet cable to the media server in the garage).
I purchased this amp as it was the cheapest upgrade from my other yamaha amp so I can get ARC. I never expected the smart Tv functions to be so good - i.e the plex media client built in - way better than the PVR DLNA solution as now I can fast forward.
