Is this a regression in function?
All the gameboy emulations have functional but imperfect sound and are flagged as such.
If you could stick to a specific instance and give us a recording of original vs. emulated perhaps something can be done about this.

For instance, sound improved as recently as 0.242 which fixed a long standing issue. Sound regressed originally on 0.179 so 0.178 and earlier may have improved sound? Can you compare that to how it is supposed to sound and make some comparison audio recordings?

It's also missing in 0.178 (and the working sound channels sound better after the 0.242 fixes), so not a regression.

I've added a recorded video of the latest version.

This recent commit seems to have added the missing sound channel, although it sounds distorted (more noticeable in gwatch4): https://github.com/mamedev/mame/commit/39f54e4399d9196dcbc84410f60d4e981fbc7ef6
