My MC24 use case is following:
If jriver source file has mch I play it as mch, if source is 2ch I play it as 2ch.
I would like to have such setting combo that is easy to use and just listen to ripped mch sacd  etc.
I can use output either over HDMI or USB.

Settings and problem:
- as in attached files, but jriver can not keep the mch setting when I change from disk to another disk.
What to do that I do not need to upload settings every time I change disk.  Setting changes and I  only get 2ch  like in picture in audio path.

Any hints how to get in an easy  mch over HDMI  as is in the source data.

Topic 2:
any  forum experiences of JRiver MCH  with minidsp   UDIO-8   solution to get mch over usb and furher via aes ebu xlr    ?

I will probably also try that reasonably priced udio-8 to get rid of hdmi related sync problems.

Could the UDIO be used for three way active speaker set-up  from jriver  with external dacs and amps   ?

I collected some  ideas of using the nice digital interface  of Minidsk  UDIO-8 and JRiver Media Center

Multichannel digital  AV player PC recipy is here:

- Take a great video player of JRiver https://jriver.com/video.html
 " JRiver Media Center offers the highest quality video available. And it plays everything, without any setup required."
- Take digital multichannel 7.1 interface  UDIO-8 to deliver lossless sound to active speakers
- home theater speaker distances need to be adjusted in jriver media player like in AV receivers
- as a new feature into JRiver there is need to create a  parameter table  into JRiver to set the (digital) speaker distances / latencies for each listening channel
- measuring of speaker distances from listening position could be done with  a feature into  REW  measurement software with UMIK mic that is in listening position on a mic stand
  https://www.minidsp.com/applications/acoustic-measurements/umik-1-setup-with-rew

Then we have created a digital JRiver Media Center  AV player  running on windooze linux or mac  and there is digital signaling support into active home theater speakers.
Room correction is done with   "plugins" into the digital signal path of JRiver or that is inbuilt in the active speakers  that adapt into listening position (example Genelec GLM concept )

Then there is no need to buy fancy fully digital av receivers because  we just  use standard PC hardware and existing operating system  functionalities and great MC application.
(Embedding the channel latency parameters into  ALSA sound card  driver input would also solve the player speaker distances topic.)

JRiver team, could you consider implementing the channel distance /latency handling with parameter table into MC  2x ?  to enable the MC MCH player fully digital E2E concept  over USB ?
