Hi,

Trying to answer some question raised by comments in the current code. 1) The card should be able to DMA to anywhere in a 64-bit address space. It is set to 32bit DMA by default. A bit has to be set to turn on 64-bit. 2) GPIOs

GPIOs SB046x / SB067x / SB0760 Bit In/Out Def Use 0: Not used 1: Out 0 Reset DAC 2: Out 0 Int_Drv_SpdifBypas (1 = Bypass) 3: Not Used 4: Not Used 5: Out 0 In_Drv_DAC_SR (0=48kHz, 1=96kHz) 6: Out 0 Back_Bracket_Lineouts_Mute (0=Mute) 7: Out 0 Mic/Line select( 0=Line, 1=Mic) 8: Out 1 Digital IO Select (0 = Digital, 1 = Analog) 9: In - Int_Drv_Headphone_Det (1 = headphone detected) 10: Not used 11: In - FP_Headphone_Det (0 = headphone detected) 12: Not used 13: In - LineOut3 detect (1 = jack inserted) 14: In - LineOut2 detect (1 = jack inserted) 15: In - LineOut1 detect (1 = jack inserted)
