Outstanding work!

I can report both Tyrian 2k and Jazz Jackrabbit work on my i5-8250u Dell laptop with HDA audio card:
Intel HDA: Intel SKL (Kabylake-LP) (80869D71) -> Realtek (10EC0256) (max 192kHz/24bit/8ch)

I did not experience any crash yet in Tyrian, but did hear the cracking audio you reported. Has been almost 30 years since I played in it real bare metal DOS with sound.

However, VSBHDA still doesn't work on my other netbook, which has strange IRQ 25 PCI Realtek ALC269 card, on the Apollolake chipset. (This was reported back in Feb '24 on VOGONS forum, and you had suggested the possibility of trying to change the interrupt line in the configuation space of the HDA).

Many thanks for getting VSBHDA working with 16-bit DPMI host games!
