Does the official dock support surround sound?

This is not about DTS/Dolby or anything like that. Just pure multi channel pcm that any linux system can already output.

Does the official dock pass through the audio properly, as what you set in the desktop mode? Or does it mangle it into stereo?

I know it does work, given the proper usb-c device. I have a cheapo hub that can do it, but it doesn't have many connections, just usb.

I have tried 2 other recommended, steam deck compatible docks, and both worked, but also both mangle the HDMI audio into stereo when fed through a surround system (on the typical HDMI connections for a device of this type). Does the official hub also do this, or does it pass it through properly?

It does work for me...most of the times anyways. For me is going over HDMI, just like my PS5 and XSX.
All I had to do was enable it in desktop mode. I get both 5.1 and 7.1 options, but for some reason 5.1 mixes the channels at least in testing mode. 7.1 seems to work fine, however, from time to time I get loud static in some games. Happens very rarely and I have to restart the game, not sure what causes it.

Does that static distortion stuff also happen when you set it to stereo? Which goes does it happen on? What do you mean by 'mixes the channels'? You mean the channels are in the wrong speaker? When you say 7.1 works, this means you have a 7.1 surround system with 8 channels, and the receiver displays it's 7.1?

Because, as I mentioned, I can certainly enable 5.1 or 7.1 in desktop mode, through the dock I mentioned, but the receiver stays saying it's stereo, and only the 2 front channels output anything.

Don't think it ever happened when I was set up on stereo. It happens when I'm on 7.1 and at random times when playing or when I fiddle with the sound settings in games.
Yes, by mixed I mean that it seems like it plays in the wrong speakers.
I have a Samsung Q990B that can do Atmos as well and can do 7.1. It's rated 11.1.
I haven't checked what the receiver says but I hear sound behind me correctly in games. The test in desktop mode for 7.1 is correctly hitting all the channels.

Fixed in the Mar 14 preview! I can play all my games with 5.1 on moonlight or docked normally. Played monster hunter wilds, yakuza 0, witcher 3, and doom 2016 to great success with surround with the dock connected to a budget yamaha reciever.

lol why does it matter if it's budget receiver or not? It works or it doesn't.

Can anyone else confirm? Has this fix gotten into stable updates?
