Audio is almost there, but not perfect yet.

ttchamp

Sound isn't hooked up yet (possibily driven by a protected PIC).

tumbleb

pangpang, tumbleb2 - Sound PIC is protected and simulation isn't 100% correct. We need a dump of the PICs.

tumbleb - Sound is not quite correct yet.

turbo

Driver needs discrete sound emulation instead of samples.

turrett

Skeleton driver. Sound isn't hooked up.

twinkle

Sound isn't fully hookep up yet (IDE DMA, finish comms).

tx1

tx1, tx1a - TX-1 tyre screech noises are not implemented yet.

uapce

The tone played by the jamma if board is not emulated.

ultrsprt

Sound cpu irqs generation is unknown and very prone to get broken (i.e. if 4G and 2G returns as bad in POST screen). Sound is lagged, reason is probably the same.

upscope

Amiga sound emulation isn't perfect yet.

vamphalf

misncrft, wyvernwg - Audio CPU isn't emulated yet (QDSP).

vegaeo

Audio CPU isn't emulated yet (QDSP).

gauntleg12 - Sound doesn't work in this clone.

cartfury, nbanfl, nbashowt - Use unknown DCS boards.

sf2049, sf2049se, sf2049te - Use DCS2 "Denver" board which isn't fully implemented yet.
