Issue description

There seems to be a recent regression which has broken CDDA when played from a CHD image. Audio behaves as if it's playing (e.g. the BIOS CD player correctly detects track lengths), but the sound is not audible. The issue was not occurring in c4b8cca from ~2 weeks ago.

Step-by-step reproduction and logs

  1. Convert any title which uses CDDA to CHD Pac-Man World (USA) (Demo) from Redump is a good test case, with a CDDA title screen theme
  2. Run that game in pcsx-reARMed
  3. Reach an area where CDDA is intended to play
  4. Crickets

Log

I don't see anything particularly useful in the log other than that it does correctly identify the CDDA tracks:

Additional notes

This is not directly related to #327, another CDDA issue. In that issue, I was using a cue+wav image, which played back without issue on the same commit of pcsx-reARMed.
