::as for AC 97 codec, the ones i have seen are connected to the PC using
::an interface chip (ES1371, YMF724, or so). To access the codec you need
::a driver for the interface chip as well. Which one did you use ?
I'm writing an audio driver for ESS Maestro2/2E sound chip.
I've been able to hear CD's with the AC'97 and Maestro2 drivers,
but still have trouble with legacy DMA (Distributed DMA). :-(
I'll send you the AC'97 driver in private mail.
Thank you for responding,
Haro
