I'd like confirmation on actual hardware before this gets looked at further. I'm not convinced that this isn't original behavior. It'll only happen on an actual machine, I'm sure, after you've entered credit/time, selected the machine and spent many dozens of seconds waiting out the transition to the control panel screen. Most games do not have lingering title screen tunes and who is going to spend up to half of their game time looking at the title screen before starting up? I'm fairly positive it was assumed that the game would be started by the user ASAP.
If there is one issue is that, in forcing a single game run PlayChoice 10 entries, we force the game to "boot" whereas the original PlayChoice 10 machines will not "boot" until you choose the game from the selection screen after coining up. This setup will be better served by a multi-slot hookup much like we have for Neo Geo games and using the bios as the main set to run.
That said, only pc_mtoid shows the hanging note as you described in my testing. pc_drmro was silent when it got to the control panel screen.

I've tested this with Linux official and GIT, still happens.
pc_drmro loops audio at the control panel screen.
When it does it return a bunch of this:
[:cart:nesapu] invalid apu write: $00 at $0009
When the game resume demo mode and get out from "hiscore", the audio loop stop and get normal all over again until it get back to the control panel screen.

Problem is now happening with pc_ttoon.
It turns into a siren while in the attract mode. The siren goes on for a while before suddenly becoming normal again.

Possible flag should be removed. This is unimplemented in mame/machine/playch10.cpp:
/* should mute the APU - unimplemented yet */
