I have not been able to get CD Audio to work from a mounted CD ISO image.

MOUNT supports the -usecd flag, which claims to enable lower-level CD things like audio playback.
IMGMOUNT does not support -usecd, even though it does support mounting CD images.

I've tried mounting the iso directly with MOUNT, which does not work. I've tried passing -usecd to IMGMOUNT, which it does not accept. Is there any way to make CD Audio function from a CD image file?

For the record, I'm running an Android build of DosBox called DosBox Turbo, and attempting to get CD Audio to play with the game Descent II, which otherwise installed and seems to play fine. I have not yet tried this setup with any other DosBox.

My current autoexec, which mounts everything and runs the game, includes:

1mount c: /storage/extSdCard/dos
2imgmount d /storage/extSdCard/dos/descenttwo.iso -t cdrom
3c:
4cd \games\descent2
5d2

I tried to search the forum for "audio" to see if this question has already been asked (as it seems like it would be a common problem), but it would seem that you can't search for that particular term, so here we are.

Any help would be appreciated.
