b1e8a6369c Some work on the sound module handling and the SB16 midi file output.
- Added the capability to load up to 4 sound drivers and added methods to
  get pointers to the waveout, wavein and midiout services of a driver.
- Rewrite of the SB16 midi file output code. In midimode 2 and 3 the midiout
  service of the 'file' driver is used. Removed obsolete midi file handling.
- Re-implemented the closemidioutput() method to make runtime changes of the
  midi setup work with the new code.

79058610d7 Moved midi output support to a separate C++ class. The lowlevel sound module
creates the object and returns a pointer to it. TODO: Rewrite of the sound
configuration to support a more detailed setup (e.g. waveout with alsa,
dummy wavein, midiout to a file).

f84439f8e8 Moved wave input support to a separate C++ class. The lowlevel sound module
creates the object and returns a pointer to it. TODO: Do the same with the
midiout feature.

0e73185efd Moved wave output support to a separate C++ class. The lowlevel sound module
creates the object and returns a pointer to it. TODO: The wavein and midiout
components should also move to separate classes. When finished, it should be
possible to configure the sound support more detailed (e.g. waveout with sdl,
midiout with alsa and the dummy driver for wavein). Creating a separate
module for the output to file(s) is also possible.

739d18c48d Changed startwaverecord() to use structure bx_pcm_param_t, too. 2015-02-08 08:53:20 +00:00

fafc153a30 Implemented support for the new mixer thread in the lowlevel sound module 'osx'
(untested). Started code cleanup in the Bochs sound code.

bfb5ec8cf9 Moved unregister_wave_callback() to the base class (only sdl has special code).
Some cleanups in the soundlow.* code.

1ccd82ab0f Implemented support for the new mixer thread in the lowlevel sound module 'oss'.
Renamed class to bx_sound_oss_c.

7dbb5185bf ALSA / OSS sound modules: startwaveplayback() rewritten to set_pcm_params()
and some related cleanups.
TODO: Replace startwaveplayback() completely.

2c621601cb Moved wave format conversion code to the sound lowlevel base class and added
format conversion support to the ALSA and OSS sound modules.

fe49c73a6b Some work on the lowlevel sound support.
- Define new structure bx_pcm_param_t and use it as a parameter for the method
  sendwavepacket(). The method startwavepacket() is now called from
  sendwavepacket() in case of a parameter change (temporary solution).
- soundsdl: Replaced waveready() call by some more accurate code for buffer
            space check in sendwavepacket().
- soundsdl: Moved code for reading from audio buffer to a new function.
- soundsdl: Temporarily increase the audio buffer size.
- Preparing the SB16 code for the OPL emulation port from DOSBox.

b84b0eed52 Moved ALSA sound support to a separate sound driver object
- ALSA stuff moved from soundlnx.* to new soundalsa.* files
- SB16 / ES1370: including specific sound driver headers not necessary
- updated dependencies

192aa1f369 Added global sound control option in bochsrc and config interface
- added 'sound' option to select the driver and the wave output device
  (see bochsrc sample for details)
- the wave device option of sb16 and es1370 is now only used to set up the
  wave input device (if necessary)
- cleaned up the speaker code to initialize the 'sound' case correctly

3a4c3e9d54 - added method to return the type of the lowlevel sound module and use it to
check if a sleep / delay call is rquired in the beep generator
- preparing SDL sound support

c6bd3fb60c - moved the sound stuff to the new subdirectory iodev/sound
- TODO #1: update MSVC workspace files
- TODO #2: these 'device classes' could be moved to subdirectories, too:
  - pci (when we have more than one chipset)
  - display (when we have one more device and vga / cirrus cleaned up)
