Nice, I'm going to test it. It would be nice to see it integrated in mplayer!

EDIT: Tested and it works (ICH7+ALC888)! but...
1) don't forget to unset old BLASTER env. var. because it tries to initialize your SB first - I had this var set bacause of partial working SB emu on SB live. So I unset it and it started. It's mentioned in readme.

2) the playback works well, smooth and good quality sound without any crackles, volume control works... Just one confusing thing is empty ioport/dma/irq value (see below, or is it due to HDA? even HDA should have some IO base and irq)

3) I tried it to compile under DJGPP 2.04/GCC 4.6.2 and it spit a lot of warnings and compiled binaries didn't work - it just blacken the screen and hangs.

4) I tried it to compile under Watcom C 11.0c and compiled binaries works fine. I think that it must got messed something with newer gcc and older may work - what version of GCC did you used? I'll try to clean up the warnings but maybe the problem is in asm part or its interconnection and then I'll be lost.
