I'm using DosBox EX v10 to try playing Alone in the Dark CD version (with CD AUDIO tracks). Following suggestions in the DosBox wiki I ripped my AitD CD to BIN+CUE files, copied it to my pandora, fired DosBox and mounted the image using imgmount:


IMGMOUNT D ALONECD.CUE -t iso
The CD image was mounted, and I was able to install and launch the game. But unfortunately, CD audio tracks sound HEAVILY distorted, and you have to turn it of just to not get dizzy. Does DosBox EX v10 support CD AUDIO tracks? Am I doing anything wrong? How can I get the music to play?

Also is it possible to RIP the CD to a smaller format like ISO + OGG? How can I do it?

Finally I figured out what the problem was. I used bchunk to extract the data and audio tracks from the bin/cue image. Then tried playing the .wav files and noticed the same extreme noise I heard in the game. Then tried again extracting data with bchunk using '-s' switch for it to swap byte order in audio tracks, and magically extracted wav tracks then played nicely  :) .

Then I generated a new cue using the extracted ISO and WAV files and the game worked perfect. My next try was trying to reduce the size of the audio tracks. Tried encoding them to OGG and modified the CUE sheet according to the instructions in DosBox wiki. It didn't work, imgmount was not able to mount the CD image. Then tried exactly the same but encoding to MP3 instead of OGG. It works like a charm! Now I can play Alone in the Dark using CD AUDIO tracks  :D .

In case anyone has the same problem, this is the final cuesheet I used:

The game plays nice, but I would like to know how to set the screen aspect ratio to 4:3 (it defaults to 16:9). Anyone knows how to do it?
 
Ops, started playing and although MP3 version mounts and the game starts, CD music doesn't play. I had to revert to WAV version...
