NODE ICON: Center Level Control Missing from Dolby 5.1-to-2.0 Downmix

The NODE ICON fully delivers on its promise as a reference-quality stereo streamer/DAC for high-resolution music.

I believe there is, however, a gap in the HDMI eARC implementation. The ICON is fundamentally a stereo product, with no center-channel output. Therefore, when receiving Dolby 5.1, high-quality 5.1-to-2.0 downmixing, including control of the center-channel contribution, is an integral part of its eARC promise.

BluOS should expose an HDMI-specific Center Level control in the Dolby downmix matrix, adjustable from 0 to +6 dB in 1 dB steps, before the center channel is folded into L/R.

This would bring the eARC experience in line with the audiophile promise the NODE ICON already delivers on music.
