Just bought a new mid range Yamaha AV amp this weekend to replace an ageing Yamaha amp (10+ years).
The new amp has HDMI pass-through whilst in standby etc.
Connected the Humax box through the amp via HDMI and all works great until I turn the amp off (to standby).
So, here is the problem. I don't use the amp all the time as I prefer only to watch through the amp when viewing HD programs with 5.1 sound. For SD channels, with only a few exceptions, I watch/listen through the TV only.
Problem begins though having finished watching/listening through the amp, I then switch off the amp (to standby).
Here's the scenario summarised;
1. Watch any channel with amp on (but best tested watching BBC HD). Sound can be heard from both the amps speakers and TV(normal volume) and HD pictures appera as HD.
2. Turn off the amp to standby.
3. HDMI signals continue to "pass-through" and picture on TV remains HD but no sound now on TV.
4. Change sound multichannel settings only on Humax 1000s to stereo and then change back to multichannel (Without leaving the page/display).
5. Sound returns to TV but picture reverts to SD (even though BBC HD in this case is still selected as the source on the Humax 1000s).
6. Only way to solve is to turn the Humax 1000s to standby and then back on (leaving Amp in standby). HD picture and sound both now okay.
Firmware = 1.00.37. Anybody else had this issue?
Problem does not occur if Humax is plugged directly into TV via HDMI and sound is channelled into the amp via Optical connection.
I also have a Bluray player which is also passed through the amp using HDMI that does not have any issue so at the moment ruling out the amps pass through as being the cause.
Thanks in advance of any help.
