I've been trying to play games with CDDA and the sound is choppy.

I'm using one card to adapt the Dreamcast's disc drive port to a SATA HDD and one 1TB SATA SSD.

I read that the best thing to do would be to convert the audio from RAW to WAV using raw2adpcm.bat, and I read about the isomake tool.

I downloaded version 2.4 of isomake, but it doesn't work for me; nothing works except optimize_gdi.bat.

I downloaded version 2.3 today, and I managed to convert it using raw2adpcm.bat, but it generated .raw.wav files, like this:

Sega Rally 2 v1.003 (1999)(Sega)(US)[!].gdi
track01.bin
track02.raw.wav
track03.bin
track04.raw.wav
track05.raw.wav , etc...

I tried running it like this and there was no sound, no music. So I edited the .gdi file to match the tracks, changing everything from .raw to .raw.wav, but still no music in the game.

Then I tried removing the .raw from the track names and leaving only .wav, ran it and nothing. After that, I put all the track names back in .raw and changed the files to .raw as well, still no music during the game.

I repeated these processes by running the gdi optimizer before and after, I don't know what else to do, can anyone help me? Thank you.

adpcm is for the SD serial port.

I didn't understand, is it an IDE mod adapted to use an SD card? Is it faster than the one I'm using, which is a SATA SSD? It seemed to be working fine in the video, but I don't know if it's the recording; it sounded like the track volume would decrease and then increase.

*EDIT*
I just saw your message: adpcm is for the SD serial port.

So, any game whose audio I convert with raw2adpcm will only work if I play it on the SD card via the serial port?

In theory, the serial port is slower than the IDE mod, right?

So, the games with CDDA should have run smoothly without audio stuttering, shouldn't they?
