HDMI on AV amplifier HDMI audio not working on AV amplifier
Posted 07 October 2012 - 03:16 PM
I'm wondering about a problem with HDMI while playing a video.
The facts : I plugged my Onda on an AV amplifier with the correct HDMI cable. In general, this kind of equipment is able to pass-through the video part of the HDMI signal, while decoding and amplifying the audio part. All home-theatres are working like that...
In my case, I wanted to listen to the audio part only.
Android recognised the link, and the amplifier also indicated "720p@60 Hz". Everything seamed OK, so I played a video. But how disappointing it was : no sound at all ! I tried many parameters, read the manual (yeah, RTFM !), etc... Nothing at all !!!!!
But I don't have the same problem if I plug my Onda directly on TV.
So, what's the problem ? Cable model, amplifier constructor, HDCP ? Or something else ?
Thanks for your help.

My amplifier is a Yamaha RX-V667. But I don't blame it.
Fortunately, I tested my VI30 Dual-Core with a direct HDMI connection on professional installation.
- no problem with a Sony monitor. 720p, 1080p and sound are working greatly !
- failure with a Kramer scaler. The scaler and the tablet are desperately trying to find each other a correct format. They both swap between 720p and 1080p, even when I tried to force it on one side.
So, I think our amplifiers are too automated... The only solution should be a firmware revision to reduce this stupid auto-negotiation between the equipments.
