Supported soundcards in the DOS version of Mpxplay:

PCI cards with native hardware access (no drivers needed):

notes:
- PCI cards detected/initialized automatically under DOS (under Win9x they
  are disabled in the autodetection) (Linux,OS/2 and other OSes are not detected,
  card will work like in DOS), under Win2K and XP they won't work at all
- maybe some cards require "Plug & Play aware OS" = "No" setting in BIOS 
  (else BIOS will not initialize it)
- usually the BIOS initializes the onboard soundchips, 
  if this is bad (not correct), then Mpxplay detects the chip, 
  but maybe the playing will not start or the output will not sound
- if Mpxplay finds an other card (or ignores the card under Win), then try
  to use -scs option
- digital/spdif outputs are not tested (maybe the analog output works only)
- bits: default is 16, you can select a different one with the -ob option
- chan: there are many 5.1,7.1 cards on the list, but Mpxplay handles them
  in 2 channel (stereo) mode only (multichannel files are converted to stereo)
- freq: Mpxplay tries to set the freq of the card to the freq of the song,
  if the required freq is not supported by the card, then the program makes
  the conversion between the input and output freqs
- Mpxplay doesn't use IRQ for PCI cards (this cannot cause problems)

- Audigy 2/4:
 - 192kHz is supported in 24-bit mode only (else 96kHz is the max)
 - 24-bit mode supports 48k,96k,192k only
 - in 24-bit mode the sent data is 32-bit, so -ob 24 is really -ob 32 (equals)
 - see sc_sbliv.c for a detailed SB-PCI soundcard list
- ICH,IHD,VIA: maybe some cards support 48k only, use -of 48000 (at wrong playing speed or bad sound)
- IHD: use -scc 1 to enable/use the (built-in laptop) speaker (else it's disabled by Mpxplay)
- IHD: try -scc 2 if you have playing problems (and you hadn't at earlier versions)

==============================================================================

ISA cards or emulation (usually requires DOS drivers):

modell name                  |  freq    | bits |chan| environment variable
-----------------------------+----------+------+----+-------------------------
SB16 or compatible (DSP 4.x) |  4k-48k  | 16   | 2  | BLASTER=A220 I5 D1 H5 T6
-----------------------------+----------+------+----+-------------------------
ESS 688,868,869,878,887,etc. |  4k-48k  | 16   | 2  | BLASTER=A220 I5 D1 H5
-----------------------------+----------+------+----+-------------------------
WSS (Crystal Sound, Yamaha)  |  6k-48k  | 16   | 2  | ULTRA16=530,1,5,0
-----------------------------+----------+------+----+-------------------------
GUS MAX                      | 22k-44k  | 16   | 2  | ULTRASND=240,5,5,5,5
-----------------------------+----------+------+----+-------------------------
SB 1.0,2.0,2.01,Pro          |  4k-22k  | 8    | 1,2| BLASTER=A220 I5 D1 T4
-----------------------------+----------+------+----+-------------------------

notes:
- Environment variables are examples only, Port, Irq and Dma values depends
  on your hardware/driver settings.
- The program usually can autodetect the card if you don't set an environment
  variable, but it's better (faster starting), if You do this before starting
  of the program (use the environment variable given by the -sct option)
- The program doesn't set/modify the volume of the soundcard automatically.
  If the playing starts, but you don't hear sound, try/use the -scv option.
- If the playing starts, but it runs very fast (4x-10x faster) or
  it plays a short block of music, after that it stops (or the program freezes),
  then your DMA (or the IRQ) value is incorrect.
  Try the -sct option, maybe it shows the correct value(s).
- Mpxplay detects the 0,1,3,5,6,7 DMA channels only, if you use a different one,
  you must configure it manually (with the environment variable).

==============================================================================

Windows sound outputs (in win32 version only):

name                  |  freq  | bits |chans| comment
----------------------+--------+------+-----+---------------------------------
WDS (Direct Sound)    |44k-200k| 8-32f| 2-8 | requires DirectX 9
----------------------+--------+------+-----+---------------------------------
WIN (Wave Mapper)     | 8k-192k| 8-32 |  2  | see notes
----------------------+--------+------+-----+---------------------------------

notes:
- 24/32/float outputs are windows-version and hardware (driver) dependant
- you can set manually (-of) a lower or higher freq than 8k/192k 
  (but maybe it will not work)
- use -sct to display and -scd to select a sub-device
- default number of output channels is 2, you can modify it with -oc option
  (multichannel audio is downmixed to stereo by default)
- maybe some old soundcards (like SB Live) requires -scc 3 setting at WDS

==============================================================================

Other audio outputs:

name                  |  freq    |bits |chan| comment
----------------------+----------+-----+----+---------------------------------
WAV (pcm) file output |512Hz-??Hz|8-32f| 1-8| writing to a wav file (-o)
----------------------+----------+-----+----+---------------------------------
bitstream output      |   -      |  -  |  - | AAC,AC3,DTS,MP2,MP3 (-o -obs)
----------------------+----------+-----+----+---------------------------------
null-output/speed-test|   -      |  -  |    | -t
----------------------+----------+-----+----+---------------------------------

notes:
- wav file output automatically uses the channel number of input file by default
- bitstream output works from containers too (ASF,AVI,MP4,TS,WAV), but only with
  the (bitstream) supported decoders
