Don't know how this relates to _inmm.dll, but if we had to keep a general page to fix this kind of issue it might be interesting to regard
Talk:Troubleshooting guide/Audio problems
CD audio is covered on Glossary:Sound, although _inmm.dll isn't covered right now. At some point I'll update it to add that method as well as the changes to looping behaviour. At least one of these solutions should work for any Windows game accessing CD audio in this way. DOSBox supports the expected behaviour so it will also avoid this issue as long as the drive or CUE sheet is mounted correctly.
