Comment (by cjover-n):

 Yes, this is specifically about the IBM PCjr sound emulation.

 I understand that the PCjr implementation was intentionally changed due to
 reported inaccuracies. However, I can confirm that I originally played
 King’s Quest V on an actual IBM PCjr, and the way it sounds in ScummVM
 2.8.0 corresponds to how the hardware behaved.

 In contrast, the current implementation produces noticeably different
 audio.

 As mentioned, I have already attached recordings in this thread
 demonstrating the differences between 2.8.0 and 2026.1.0.

 Thank you for taking the time to review this.
