Audigy 2 support for the P16V HQ chip.

Audigy 2 support for the P16V HQ chip.

[James Courtier-Dutton]

This is just a quick update to say that I have managed to get sound 
output at 96khz and 24bit from the Audigy 2 card using the P16V chip.

I will post some details later.

Cheers
James

For those interested, the alsa p16v driver is at 
http://www.superbug.demon.co.uk/alsa/p16v

It currently supports playback to 5.1 channels, output at rates 44100, 
48000, 96000, 192000. 24bit.

I will be adding capture support next, so we should finally be able to 
capture AC3 input via the spdif inputs of the Audigy2.

The driver uses DMA for direct CPU to P16V chip data path, bypassing the 
EMU10K2 entirely.

I will keep the p16v driver separate from the emu10k1 driver until I 
have found out enough about the P16V chip.

Cheers
James

If it were to work for audigy1, too, we can split emu10k2 from
emu10k1...

I have no idea if it works on the Audigy1 or not. Someone else will have 
to try as I don't have an Audigy1.

I will try it this weekend on Audigy 1.

I just start to think that maybe Audigy 1 contains this p16v unit 
too, but is not used and CA0151-DBS chip is something like switch or 
router between i2s inputs. But I don't think it will work. Maybe it 
is used on Audigy 1 for 96 kHz spdif output, only Creative knows. I 
don't know.
