Steam Remote Play (streaming) and audio

B

Blue|Fusion

Hello all,

I finally got around to getting Steam on my HTPC running 13.1-RELEASE-p2 and am having an issue I can't figure out how to go about diagnosing or solving. Steam itself works fine. Being a lazy, old Intel i5-4xxx series with the integrated GPU only, I use my Linux desktop as the Steam host to stream from. This setup worked well when I had Linux on my HTPC, but with this setup I can not get in-game audio on the client HTPC.

For what it's worth, I am running KDE Plasma (kde5 meta package) under X11 with PulseAudio from the official "latest" FreeBSD package repository. Steam was installed using the linux-steam-utils package and associated instructions.

Please let me know what would be helpful to assist in the diagnosis of this.

Additionally, I tried streaming from a Windows 10 Steam host and the results were no different - no in-game audio.
 
We disable PulseAudio on the Steam/game side (besides being obnoxious in general, it's prone to crashing with mutex-something issue under Linuxulator with CentOS 7 libs). That in turn means it can't be used for capturing sound, which likely is the feature that Remote Play relies upon. I don't think that would be fixed any time soon.

Although, if the direction is specifically Linux -> FreeBSD, then I can't really tell. Never looked into it, never will.

Yes it is Linux -> FreeBSD and also tried Windows -> FreeBSD. During streaming I see man of these lines in dmesg:
Code: 
linux: jid 0 pid 69643 (SDLAudioP2): unsupported socket(AF_NETLINK, 3, NETLINK_ROUTE)
linux: jid 0 pid 45622 (COfflineMessage): unsupported setsockopt level 6 optname 18
linux: jid 0 pid 70283 (Thread 0x0x2a98): unsupported socket(AF_NETLINK, 3, NETLINK_ROUTE)
linux: jid 0 pid 70283 (SDLAudioP2): unsupported socket(AF_NETLINK, 3, NETLINK_ROUTE)

I did a precursory search of some documentation and web search. I couldn't find anything concrete on if these are critical to the issue or a red herring.

Additionally, I tried running the game Portal on the local FreeBSD machine with the same lack of audio problem.
