How would I do that?
Remove pegasos.audio from MOSSYS:Devs/AHI and reboot.
I thought that by selecting emu10kx on Music unit and Units 0 - 3, on
board sound would be automatically disabled.
On-board audio is still available if app or game bypasses AHI prefs.
And I think Feeble Files bypasses AHI prefs now.
