#15919: HOYLE1: MT-32 Emulation has significant right-side audio balance bias

    Type:  defect                   |     Status:  new
Priority:  normal                   |  Component:  Audio: MT32
 Version:                           |   Keywords:  MT-32, Stereo, SCI
    Game:  Hoyle's Book of Games 1  |
------------------------------------+--------------------------------
 Windows 11 Home, 24H2, 26100.3915.

 Using MT-32 Emulation, the music is noticeably panned too far to the
 right. It's not completely right-only or anything, but it's very
 noticable. Running the game in dosbox-staging (0.82) using MT-32 settings
 does not have this issue. Though I have limited access to other games
 right now, this issue does appear in sci:christmas1990 as well.

 A notable aspect of this is when using the current stable build (2.9.0),
 this issue applies to Ad-Lib emulation as well! However, running the daily
 (2.10.0git14681-g8f5500d05be) fixes this issue, but not the MT-32 one.
 I've been swapping between the two builds' versions of scummvm and
 winsparkle.dll using the same config to test; there's some notable
 differences in volume as well but that's probably known/intentional. An
 important adjunct to this is that the stable build does NOT have this
 issue with scumm:pass in Ad-Lib, just the two SCI games I tested. I
 unfortunately do not know of an MT-32 supporting non-SCI demo or other
 free game to test here.
