Looking for help with ALSA

[mscott pyewacket.org]

I recently set up a computer to play a series of video files using vlc.

Everything works except the sound comes out of the PC speaker rather than the speakers on the connected HDMI monitor.

The OS is Debian bullseye (11.4.0) with non-free drivers.

I believe the hardware is being recognized, but since the display was not connected when I installed the OS, it isn't the default.

I've been looking at stuff online and my eyes are starting to glaze over.

Is there a config I can change to switch the default output device to one of the HDMI outputs?

I'm willing to apply trial-and-error.

aplay -l is as follows:

**** List of PLAYBACK Hardware Devices ****
