Intel HDA audio driver is available for Menuet64. M64 also has under 1 ms audio latency, or even under 0.1 ms audio latency. Part of the latency setup is adjusting the scheduler interval up to 0.1 Mhz.
Thanks! ("Time to move on" = mmmaybe put those 32-bit machines aside, ohwell; I'm long time aware and still curious about MenuetOS, also as a huge fan of minimalist systems. The Dell Mini 9 is a really cool fanless netbook, though, esp for the ~5€ I paid for it, ha. Would be great to test MenuetOS with audio on it as well. That M64 latency is surely impressive.)
