Steam in LXC container failing audio

Hello.

I have an arch linux host and created an unpriv. arch linux lxc container called archie inside there.

I use `xhost +local:` on the host, and the following profile on the container

config:
  environment.DISPLAY: :0.0
  environment.PULSE_SERVER: unix:/home/archie/pulse-native
description: X11 LXD profile
devices:
  PASocket1:
    bind: container
    connect: unix:/run/user/1000/pulse/native
    gid: "1000"
    listen: unix:/home/archie/pulse-native
    mode: "0777"
    security.gid: "1000"
    security.uid: "1000"
    type: proxy
    uid: "1000"
  X0:
    bind: container   
    connect: unix:@/tmp/.X11-unix/X0
    listen: unix:@/tmp/.X11-unix/X0
    security.gid: "1000"
    security.uid: "1000"
    type: proxy
  mygpu:
    type: gpu
name: X11
used_by:
- /1.0/instances/arch
- /1.0/instances/archie

which provides X connection, video accel, and pulseaudio works inside the container. (once we `sed -i "s/; enable-shm = yes/enable-shm = no/g" /etc/pulse/client.conf` on the host)

The problem that I am having is that steam games (Baba is You, Recursed, Snake's Tale) do not have sound or do not launch and I think it's because they fail to get audio (Yankai's peak does have sound). Some errors:

Opening audio device
corrupted double-linked list
/home/archie/.local/share/Steam/steamapps/common/Baba Is You/run.sh: line 10:  8772 Aborted                 (core dumped) "./bin64/Chowdren"

[ALSOFT] (EE) Failed to set real-time priority for thread: Operation not permitted (1)
Failed to open the audio device
[ALSOFT] (EE) Failed to set real-time priority for thread: Operation not permitted (1)
Failed to open the audio device

I am not sure how to diagnose this problem or troubleshoot it so if anybody could recommend some tools or things to try that would be very kind! thanks.

I updated both at the same time to ensure all the libraries are at the same versions. I installed pulseaudio-alsa on the host and container, lib32-libpulse and lib32-alsa-plugins on the container.
