- Moved BX_INIT_MUTEX() call to start_mixer_thread() to reduce code duplication.
- Call BX_FINI_MUTEX() only when the mixer thread and mutex was really used.
- 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.
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).
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.
'alsa'. Cleaned up the code a little bit.
TODO #1: Implement mixer thread support in the OSX sound driver.
TODO #2: Code cleanups in the Bochs sound code.
TODO #3: Resampling support and improvements in the wave recording code.
- soundlow: prepared code for 2 pcm parameter sets:
emulated: requested by sendwavepacket()
real: used for the sound output
- soundsdl: startwaveplayback() rewritten to set_pcm_data().
- soundmod: some beep init code fixes.
- 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.
- ALSA stuff moved from soundlnx.* to new soundalsa.* files
- SB16 / ES1370: including specific sound driver headers not necessary
- updated dependencies
