Someone think of the audio
And yet, no-one has a device that can handle (de)embedding analogue audio <-> HDMI for 7 or more channels. Does anyone know of such a device?
I have a very nice receiver (Onkyo TX-NR3008) that does everything I need but would have to be junked in the move to Atmos. I would have liked to have used a cheap Atmos-enabled receiver (such as Marantz SR5010), passing the usual 7.1 channels to my current one as it has Audyssey XT32, leaving just the overhead channels to be powered by new receiver. Note that you can't just daisy-chain the HDMI signal as-is because that would be a downmixed version of the Atmos track.
In order to do that, I'd need a pre-out (analogue) to HDMI converter as the multi channel input on the current amp bypasses all digital processing.
Still looking for a solution that doesn't involve getting a PC to digitise 8 channels of audio then routing that to HDMI (have you seen the cost of high quality 8 channel ADCs?).
