I don't think that this patch is correct. DMA transfers should be disabled by:

outl(what, TRID_REG(trident, T4D_STOP_B)); outl(val, TRID_REG(trident, T4D_AINTEN_B));

They are already in the trigger callback as long as I saw the code quickly. So the problem should be somewhere else.

lines. Adding &= ~SPDIF_EN can disable output from AC97 to S/PDIF as well.

That's true.

Anyway, if you are up now, I'll let you hunt further as you are the author of the driver :)

Are there any specs on this hardware? I could play around a bit myself, but I can't really find any documentation on the registers.
