There is another bug that exists in all OS from 10 down to XP, possibly on older systems as well. If you pause CD playback via MCI then query its status, you'll get back "stopped" instead of "paused".

DxWnd emulates the bug by default, but has an option to enable proper behavior - "Emulate CD pause capability".

It has worked that way since Win9x so if it is a bug it is a really old one. In any case it seems to have no practical effect since after MCI_PAUSE the music can be resumed from where it left with the following MCI_PLAY command. The fact that the mode says "stopped" instead of really being "paused" may indeed be an oversight but the logic seems to work otherwise.

This problem exists in Grim Fandango and Interstate 76. The music actually stops there, instead of pausing. For Grim Fandango, setting options for MCI Audio in DxWnd doesn't help. It sometimes hold the music then it stops playing anymore.
Another thing I noticed is that some games don't play the next music after 1 is over.

The two CD box set I have of Grim Fandango does not have cd music tracks. The music is instead played digitally from files as far as I can tell.

Strange, the music stops at menu. I decided to turn on the emulate cd pause capability and some other related options in DxWnd. Suprisingly it holds the music but not when you go one further step in menu. The music sometimes glitches and buffers. Not sure why but that MCI setting has effects.

I tested Grim Fandango and the issue is not related in any way to cdaudio or MCI_PAUSE capability. The game mutes all sounds if you access the main menu (F1) key.

You can fix it by patching the game to v1.1. The patch is available at the ResidualVM web site under "Extras downloads":

It's basically a timing issue. Running in single core affinity may also help...

I fixed it, thanks.

Btw I found Midtown Madness and MM2 using CD Audio and MM sound pauses in Pause Menu. MM2 music doesn't work at all but Audio is playable on WMP. I think it has that issue seeing similar MCI_PLAY problem for MM
