92f48fa92f Implemented MIDI output support for the ES1370 soundcard. Data written to the 
UART data port is sent to file or device similar to the SB16.
Minor cleanups in the SB16 code.

2bfe0f523e Some work on the documentation for the "waveout" class methods (not yet complete). 2015-04-14 18:41:39 +00:00

091e01d96c Fixed UART register address in condition and added default status return value. 2015-04-12 10:48:02 +00:00

727fbd23af Fixed possible deadlock when pressing user shortcut or save/restore button. 
The button handlers must be placed outside of the critical section.

035b133bac Improved error messages for unsupported internal memory access. 
ES1370 is no longer "experimental".

d8ca04c79f The current frame count registers are readable as word (not mentioned in specs). 
This fixes the Win98 explorer crash.
Added BX_ERROR for the still unsupported dual output mode.

bad6c96fc7 Fixed possible compilation failure caused by container_of definition (part of 
the mixing6 patch by Dawn Teschendorf).

93d9356899 Added documentation for the new lowlevel sound classes. The sections for the 
"wavein" and "midiout" feature should be okay. TODO: Update "waveout" methods
subsections.

696c1a6e55 Some Bochs features are still called "experimental". The bus mouse, USB OHCI, 
USB UHCI and the E1000 NIC are known to work fine on some guest systems, so
it's safe to remove this attribute.
TODO: Some other Bochs features need to be reviewed for this.

a52bcdfa88 Minor fixes and cleanups in the SB16 code (no functional changes). 
- the "remaplist" has 256 entries, but the limit was too high (4096).
- the "patchtable" had 4096 entries, but the index was never > 15.
- removed disabled / outdated code.

a256414d32 Some work on the ES1370 emulation. 
- Undocumented "legacy" register at offset 0x1b is used to probe for the ES1370
  interrupt by the Win9x driver. Using bit #0 to control the IRQ line fixes
  driver installation.
- Added more detailed BX_ERROR messages for the UART registers.
- Small code cleanup in the write handler.
- TODO: fix possible bluescreen in Win98 guest after wave playback.

79278be63f Volume control fixes and improvements 
- OPL3: apply FM volume control to the output data.
- SB16: fixed missing volume update after mixer reset.
- soundlow: fixed application of the volume control to the PCM output.

d93eeb98be Updated workspaces after adding Oracle(tm) VM VirtualBox image support. 2015-03-30 20:27:06 +00:00
Volker Ruppert
72cbbe9e8b Fixed incorrect calls of virtual functions in constructor/destructor. 
- Removed useless set_pcm_params() call in base class contructor.
- SDL waveout destructor needs to call the unregister_wave_callback() method
  of the SDL stuff, since the base class destructor doesn't do that.

3e54ff2e36 Added Oracle(tm) VM VirtualBox image support (VDI version 1.1). Patch written 
by Ben Lunt plus some additions (bximage fixes, big endian support).
TODO: update MSVC workspace files.

601493c89a Moved output volume calculation to a separate method and prepared volume 
control for the FM output.
TODO #1: handle volume control in the opl code.
TODO #2: check if the output level calculation is correct.

927e55f077 Improved mixer thread mutex handling. 
- 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.

8fe902686c Separated sound lowlevel base class from dummy driver. The base class returns 
NULL for all services and the dummy driver provides the stubs. Now falling
back to the dummy driver if the wavein or midiout services are not provided
by the selected driver.
