 Hello ScummVM team,
 I would like to report a possible regression in the IBM PC audio emulation
 starting with version 2.9.0.
 Since ScummVM 2.9.0, the IBM audio emulation does not behave the same as
 before. In my experience, the correct and accurate audio emulation was
 present in version 2.8.0.
 I have verified this using King’s Quest V. This is a game I originally
 played on a real IBM PC, so I am familiar with how the audio should sound
 on original hardware. From version 2.9.0 onward, the audio sounds
 noticeably different and no longer matches what I remember from the real
 machine, whereas 2.8.0 matches the original audio behavior correctly.
 For this reason, I believe that the IBM audio emulation in 2.8.0 is more
 accurate, and that something may have changed or regressed in 2.9.0.
 Thank you very much for your work on ScummVM and for taking the time to
 look into this.
