Spotify audio hanging after one song with HDMI output over USB-C

[jamesmcm]

System details

Omarchy 3.0, DELL U3818DW monitor with built-in USBC and speakers, Meteor Lake-P HD Audio Controller from Intel(R) Core(TM) Ultra 7 165H - Lenovo Thinkpad G7 P1 (16", Intel, 64GB RAM, Nvidia RTX 2000 model)

What's wrong?

This seems to be happening specifically with audio over HDMI via USB-C (to a Dell monitor).

I was able to "fix" this by instead launching Spotify with:

bindd = SUPER, M, Music, exec, spotify --audio-api=pulseaudio

That seems to work fine, but I wanted to log this issue in case anyone else hits the same problem.
