Is there an Roon endpoint that supports multichannel?

Very true, except that the new M1 processor chokes the 5.1 sound quality for reasons only Apple knows. A good 2012/2014 Mac mini does a much better job with 5.1 files.

I have recently implemented this as well, based on a post by Archimago on his blog - works very well!

Very odd, hadnā€™t heard thatā€¦

The M1 mini I bought a year or so ago would not support 5.1 output beyond 44/16. I returned it after my research showed this choke as a feature, not a bug. Found a good used 2012 with 16 gbs RAM for fewer $$ that delivers 5.1 and 2.0 in full res. I am a Mac guy of more than 35 years, but I fail to see the reasoning behind this decision.

Thatā€™s what I use and works very well. I originally tried linking my NUC to my Oppo 205 and then to my AVR but it just played in stereo so just link my NUC directly to my AVR.

If you have a receiver with analoge multichannel input you could have linked your Nuc to your Oppo 205 and used itā€™s analoge surround outputs to the receiver. That works. Iā€™ve done that with my Media PC.
Going directly from Nuc to Receiver also works fine indeed.

Unfortunately my receiver doesnā€™t have analogue inputs so canā€™t use the Oppo in this fashion.

Today I tried to use a Pi4 with dietpi and can confirm that multichannel audio works.

  • Dietpi version - v9.9.0
  • Dietpi kernel version - 6.1.21-v8+ #1642 SMP PREEMPT

My setup

  • Pi 4 connected to ethernet via cable (will try wi-fi later as the back of the TV already looks like a jungle)
  • Pi 4 connected to an HDFury Arcana as my TV (LG 55C8) does not have an eArc. It also means I can run this with the TV off
  • HDFury Arcana running into a Sonos Beam 2 attached to Sonos sub 3 & 2 x Era300s
  • Pi4 HDMI Connection (bcm 2835 HDMI) in Roon setup as : Max sample rate (PCM) - Up to 192KHz / Zone grouping delay(ms) - 0.0 / Clock master priority - Default / Enable MQA core decoder - no / Buffer size - Default / Channel layout - 7.1 / Send stereo / mono content as 7.1 - no / Swap rear and surround channels - no / Multichannel mixing - Channel mapping only

One strange thing I have noticed, I am playing a 6 channel dsf file and it outputs in 7.1. In the Sonos app it says the source is a Multichannel PCM 7.1. Something I might take a look at later.

Hope this is some use to someone.
