Hi new owner of Naim Nova and Kef R7’s which for the most part will be used for streaming audio from flac files on local server or Tidal Spotify etc.
I will also use to listen to music from TV. TV audio will normally be via a Sonos Arc sub rears system, which uses the HDMI arc. Should I find some way of switching HDMI from Sonos to Naim or just run Naim via Optical from TV Media box ?
I found that a hdmi switch for that purpose is a quite cumbersome solution.
I would use the optical port as i don’t see any benefit or using automatic switching when listening to music.
May i ask why you want to listen to music from the TV? I find it quite a distraction and with my 4k OLED TV it is not only going against burn-in behaviour but also consuming more than 100W for nothing.
I also suggest splitting ARC and optical.
This might also save you the effort to toggle between TV-out of 5.1 on HDMI-ARC (for the Sonos) and setting 2.0 (stereo PCM) on the media box for the digital out.
You loose a bit of convenience (auto-switching/power-on/off on ARC input, volume control control via TV remote), but switching between setups should be very simple and for a secondary/occasional use case, this sounds reasonable to me.
I get the surround bit and I’m an ex-Sonos owner but I guess to each his own, as I prefer proper speakers still for movies.
It’s also not as straight forward switching Sonos to non-Sonos. I had to also go to the TV settings and change the audio output from PCM to Dolby 5.1 for my surround to work properly. So it ended up being a big hassle.
