AUDIO: Sound skips/pops/stutters on all ScummVM versions on Windows 10/7

Description

I've been having this problem at least as as long version 2.5.0 and no amount of tweaking configurations or sound card settings seems to help: https://forums.scummvm.org/viewtopic.php?p=97729

Here's a few things I've attempted to solve it, but none has really worked long-term:

*Turn on VSync (if you have a monitor with GSync or FreeSync it should allow vsync to be turned on without the laggy mouse feel)
*Add audio_buffer_size=8192 to scummvm.ini (it'll disappear when you run scummvm, but it's still there it's just moved below subtitles)
*Run with compatibility mode for Windows Vista (7 and 8 might also work)
*Disable fullscreen optimizations
*Try your soundcard at 44100khz and/or set scummvm's output_rate to the same.

Particularly The Dig is causing me skips and stutters every few seconds, especially if I talk, and Sam And Max did it more often than anything else, especially with Nuked OPL enabled.

Thanks for the report, are you loading the game data from a local hard disk or something else (optical drive / usb / network mount ...)

Also, could you confirm that the issue also happens on non-scumm games? (If you don't have any available, you can get some freeware and demos from our site)

Replying to tag2015:

It's from an SSD.

It glitches on Laura Bow 2 and other Sierra games, although that's more of a glippy sound than popping, it still happens during any dialog (and pretty frequently).

It seems that setting the sound card sample rate to 4100hz fixes almost any glitches, but I often have it set it to 48000hz, can ScummVM not exclusively change the card's sample rate? I've tried setting it in the config but it never works.
