Yes, and no. Depending on what you want, and how you setup the containers.

One way to do it is to give containers access to the hardware
directly, often meaning that only one of them can use the hardware at
the same time.

That's another way to do it: give containers access to host resources
(e.g. X, audio) via unix sockets by setting bind mounts manually

correct for the second way.

... and that's the third way. Treat containers like another headless
server, and setup remote GUI access to it appropriately. My favorite
is xrdp, but vnc or x2go should work as well (I haven't tested sound
though, didn't need it)

Note that if you need copy/paste and file transfer support in xrdp,
your containers need to be privileged with access to /dev/fuse
enabled. If you don't need that feature, the default unpriv container
is fine.
