I don’t know if this applies to CLAW, but many games back then had their audio stored as CD Audio Tracks. If that is the case, you might want to actually emulate a CDROM drive instead of just extracting the files. There is a CDROM emulator for Linux, called CDEmu, which can read CUE/BIN CD Images.
Oh, and that game seems to have an ancient 16-bit installer, which might not work on modern systems. However, according to WineHQ Appdb one can just copy the files from the CD and it works.
