Excellent, the first drivers (not XDMAx) are working wonderfully:

pcm0: <Envy24HT-S audio (Chaintech AV710)> port 
0xb800-0xb81f,0xb400-0xb47f irq 22 at device 1.0 on pci2
pcm0: [GIANT-LOCKED]
pcm0: system configuration
   SubVendorID: 0x1412, SubDeviceID: 0x1724
   XIN2 Clock Source: 24.576MHz(96kHz*256)
   MPU-401 UART(s) #: not implemented
   ADC #: 1
   DAC #: 3
   Multi-track converter type: I2S(with volume, 192KHz support, 24bit 
resolution, ID#0x4)
   S/PDIF(IN/OUT): 0/1 ID# 0x00
   GPIO(mask/dir/state): 0xff0000/0xff0000/0xff0000



mplayer -format s32le WAV output:

AUDIO: 96000 Hz, 2 ch, s24le, 4608.0 kbit/100.00%
AO: [oss] 96000Hz 2ch s32le (4 bytes per sample)


(Now to work out how to play .FLAC files (mplayer FLAC is choppy)...

Thanks,
