[Qemu-devel] Audio patch

[Qemu-devel] Audio patch

[Fabrice Bellard]

I commited the version 6 of malc's audio patch. Tell me if you see 
problems. Maybe SDL audio support could be enabled on Mac OS X ?

The version 7 of the patch is not acceptable in its current state as C++ 
is forbidden in QEMU.

I would *love* to have SDL audio support for the Mac.  Perhaps even a 
-sdlaudio switch from the command-line?

Another possibility would be using the liboss library 
(http://liboss.sourceforge.net/), although the project doesn't seem to 
have had much activity of late.  I don't know how viable it is, what it 
would take to implement, or even if it's robust enough for Qemu, but it 
might be worth looking at given the limitations of SDL audio that 
you've mentioned in the past.

For the time being (until C++ magically disapears) 7c_aqemu which should
in apply cleanly to the current CVS is available at:

How about somebody uses AT&T's cfront or SUN's GCC2C to convert those
templates in mixeng.cc to plain C? The code won't be pretty, but it will
make more sense than handcoding the stuff.

I guess one could also use some smart macros to replace the templates.

A beautiful dream, my friend.

Moreover mixeng.cc uses floats, which are also forbidden in QEMU, except 
for CPU emulation :-)

I'm no big C++ fan myself, but credit where it's due, changing these to
int32_t or whatnot is as simple as changing template argument and clamping
code in ONE place - now beat that stupid C99 ;)

Please try the attached patch *after* applying 7c_aqemu. It removes the
need for template Fabrice's Way(TM). I could not test it yet (sitting on a
box without sound card...).

Ciao,

Doesn't work for me, windows report the device as working but no sound
output.

Sorry, still could not test, but one thing is for sure: At the beginning
of mixeng_template.h, the four definitions of HALFT and HALF: could you
change them to

#ifdef SIGNED
#define HALFT (float)(IN_MAX)
#define HALF (float)(IN_MAX)
#else
#define HALFT (float)((IN_MAX)>>1)
#define HALF HALFT
#endif

and test again?

Sorry,
Dscho

Still the same thing: card reported ok but no output at all.

My soundblaster did the same thing.

Malc had a fix for this...

"If you are using Win98 guest make sure that 16bit DMA for SoundBlaster is
set to 5"
