It is definitely possible, you need to mount /dev/snd, see how Jess Frazelle launches a Spotify container, from

https://blog.jessfraz.com/post/docker-containers-on-the-desktop/

you will notice

docker run -it \
    -v /tmp/.X11-unix:/tmp/.X11-unix \ # mount the X11 socket
    -e DISPLAY=unix$DISPLAY \ # pass the display
    --device /dev/snd \ # sound
    --name spotify \
    jess/spotify

or for Chrome, at the end

docker run -it \
    --net host \ # may as well YOLO
    --cpuset-cpus 0 \ # control the cpu
    --memory 512mb \ # max memory it can use
    -v /tmp/.X11-unix:/tmp/.X11-unix \ # mount the X11 socket
    -e DISPLAY=unix$DISPLAY \ # pass the display
    -v $HOME/Downloads:/root/Downloads \ # optional, but nice
    -v $HOME/.config/google-chrome/:/data \ # if you want to save state
    --device /dev/snd \ # so we have sound
    --name chrome \
    jess/chrome
