I have an Intel NUC setup (win 10 pro connected to a receiver) as a HTPC running plex media player.

Occasionally when it wakes from sleep or more often when Win 10 does an update/ auto reboot, the speaker configuration switches from 5.1 to 2.0.

Does anyone know if there is a registry setting or other method that can be used force 5.1 speaker configuration.

Appreciate any help given.

Sorry - its within windows.

The NUC is setup to do an auto login and start PMP at start-up.

When I have known there has been a windows update I've disabled PMP from running on start-up and done a manual check/update/reboot to windows and the problem can still occur so I don't think its PMP/app related. The only other apps installed are steam (used for remote play only - no games installed) and Kodi. I use these seldom so its less noticeable but it has happened with Kodi a couple of times.

I've also removed/reinstalled/updated the Intel drivers as well.

Previously I had the same setup with Win 8.1 and never had this issue.

some of the time when im dealing with windows+amps via HDMI in home theatre setups i end up just getting a HDMI detective so the AMP side is always presenting

the correct info to Windows, stops windows from changing resolutions etc when the amp is off, then changing back when its on

if you installed openpht and set the channels within openpht, passthrough enabled, i dont think its going to care what windows says the speaker setup is, you could give that a try if you

dont find a solution

See if the amp is just passing the TVs edid thru when it is off. That was an option on a friends amp that caused the same problem, as the amp being off windows would see 2.0 and change, only to never change back to 7.1 that the amp was when it was powered on. There was a HDMI option to pass thru when off which when disabled stopped this happening.

Thanks for the suggestions

I'll keep openpht in mind but I don't really want to move to change as I have a few devices running plex and need to keep things semi-consistent for the sake of others.

Ive done a bit more digging around as well.

hdmi pass-through is not enabled but I recall enabling ARC (TV Audio Return Channel) about the time I started seeing my problem. - long shot but who knows.

It also seems to be about when I installed win 10 anniversary update.

I'll see if disabling ARC makes a different and if not I might do a clean install.

Thanks

Thanks @richms

It wasn't passthrough but your suggestion did make me look at it and other associated settings.

I had ARC enabled on receiver (Pioneer) but disabled on TV (LG).

Disabled it on receiver and its been behaving nicely since then.
