This can only be done for the CD versions of certain games, such as Monkey Island 1, Loom, and Gobliiins. All the floppy games and CD games that didn't have CD audio tracks for music don't require any conversion, and will work unmodified on ScummVM DS.
Cdex can do the conversion very well and I recommend using it to convert your audio files, although any CD ripping software can be used, so feel free to use your favourite program. The format you need to use is IMA-ADPCM 4-bit Mono. You may use any sample rate. All other formats will be rejected, including uncompressed WAV files.

Format: WAV
Compression: IMA ADPCM
Samplerate: 22050 Hz
Channels: Mono
On the fly encoding: On
Now all you have to do is copy the newly created WAV files into the same directory that your other game data is stored on your CompactFlash card. Next time your run ScummVM DS, it should play with music!
