When I try to run Doom I & II on UniPCemu's current version, somehow (setting all audio settings to Sound Blaster with the IRQ 5 and DMA 1 (as UniPCemu uses)) there's no background music and only some kind of noisy sound?

Anyone knows something about this issue?

Just tried the Generic MIDI synth settings with Doom I & II. Both work just fine(both with the slow emulated GM synth UniPCemu has(slow because it's trying to accurately do it using floating point math pretty much) and with the normal Windows synth passthrough).

Perhaps it's not detecting or handling the adlib or sound blaster DSP data correctly? I see the sound blaster having an auto-initialize value of 0x7F? Is that correct for Doom?
