********************************************************************************
This is a library of sound cards based on the modified mpxplay_source_code me
 (Ruslan Starodubov).
The library can be compiled for different memory model (for WATCOMC and DJGPP).
Maybe use it in any projects for sound programs DOS.
All changes its code let me know. (starus2009@mail.ru)
********************************************************************************

//main soundcard routines:
char* AU_search(unsigned int config); config = 0 (for LINE_OUT) or 1 for STEREO_SPEAKER_OUT (only Intel HDA chips)
uint AU_cardbuf_space(void); return free space in buffer (sample position)
void AU_start(void); start DMA
void AU_stop(void); stop DMA
void AU_close(void); close device for EXIT
void AU_setrate(unsigned int *fr, unsigned int *bt, unsigned int *ch); *fr pointer to int frequency; *bt pointer to int bits_sample; *ch pointer to int channels (1 or 2)
void AU_setmixer_all(unsigned int vol); set volume all mixer in % (per cent)
void AU_writedata(char *pcm, long len, unsigned int look); write data_sample (*pcm) to buffer; look - bool for EXIT any press KEY

use compile directive ZDM for disable __djgpp_nearptr_enable() (only for DJGPP)
