[Qemu-devel] Sound and MinGW problems on Windows host

[Qemu-devel] Sound and MinGW problems on Windows host

[Tomasz B±tor]

Hi.
I have a few problems using QEMU on Windows XP host and MS-DOS guest.

1. Sound is very choppy. And I mean _very_. It's not usable at all.
Under Linux there's no problem.

2. Sound only works at 22050 Hz, setting 44100 make it go silent.

3. As Natalia Portillo noticed in different thread, compiling CVS
under MinGW creates the binary, but it's only runnable under MinGW
itself, directly under windows command prompt it exits immediatelly.
There'd be no problem, but within MinGW the sound doesn't work at all.

I tried patches from http://www.h7.dion.ne.jp/~qemu-win/,
but without any success.

I used binaries from http://www.h7.dion.ne.jp/~qemu-win/
(qemu-20040621-windows.zip) and from http://www.freeoszoo.org/
(QemuInstall_20040705.exe) with the same result (choppy sound
and 22050 only). Sources from 07.04 and original 0.5.5 compiled
and worked fine (more or less) under linux.

Can anyone give me any hints? I've searched through archive, but
I didn't find the answers.

t.

Hi Tomasz,

I have the same configuration here (WinXP Home host / Freedos guest).
It plays modules in ScreamTracker as if they were open in Winamp.
(sound is mono though ;)
Make sure you have correct setup for adress/irq/dma/hdma
and try to change the software, some use still unimplemented DSP commands.

Make sure you applied sound patch to enable it in MinGW
and check the output of configure.

I successfully compiled CVS under msys/MinGW and ran it outside it, however
before compiling I edited CONFIG_QEMU_SHAREDIR in config-host.h to "."
(otherwise it's set to $prefix, which is by default "/c/Program
Files/Qemu"). If you remove -mwindows from CFLAGS and run qemu from command
line, you can usually see why it immediately exits (though the very latest
CVS doesn't seem to output anything anymore)

Could you tell me the difference between dma and hdma? In DOS-times
I wasn't using PC ;). Now in setups I use 220h/irq 5/dma 5

I use QEMU for watching demos, so the sound players differ very much.
I'm surprised though that some standard stuff like MIDAS also cause
trouble, but there're some experiments ahead of me ;)

After a "few" tries I finally compiled it with sound and console support in
windows, but there're still strange trouble like those above. Sound chopping
is still there (I read somewhere on Bochs' forum that this problem is
known to them too. Windows? SDL?), but in some cases the higher frequency, 
the lesser the problem is. On 44100 it's like 2 seconds smooth, 3/4 second
garbled, 2 seconds smooth, 3/4 second garbled and so on (more or less).
On 22050 there're 0.1s "chops" all the time, it's not smooth at all.

I have one more problem in 07.04 version on windows: full screen doesn't
work. QEMU just quits.

Both sound and fullscreen problems are not present when I run QEMU (from
the same sources and patches) under linux.

Anyway, thanx for your answer. I'll keep my fingers crossed for the developers
to make QEMU better for an usual user ;)

I solved that immediate exit without output by applying
qemu-20040621-monitor.patch.gz and changing manually LIBS in i386-softmmu/Makefile
(I only compile i386-softmmu), so it looks like:

DEFINES+=-D_GNU_SOURCE
LIBS+=-lm
ifdef CONFIG_WIN32
LIBS+=-lwinmm -lws2_32 -liphlpapi -mconsole
endif

After that, the console in windows is back.

does anyone know why the mandrake linux img from the freeoszoo won't 
work?

This could explain why the sound is choppy for you...
A dma is a direct channel for memory access.

DMA from 0 to 3 have 8 bit access, and
DMA from 4 to 7 have 16 bit acess (these are HDMAs)

Youre using the dma 5 (16 bit) when it should be a 8 bit acess.
Current config for qemu is (in DOS settings) :
SET BLASTER=A220 I5 D1 H5 T5

D1 is dma 1, H5 is for hdma 5.
T5 means Soundblaster 16

That's not the problem. Setting DMA to 1 don't change anything for me,
and as I said earlier, on Linux even with DMA=5 I have no problem at all.
On Windows - choppy sound :/

Hmm, nice. I've just tested it, and with QEMU_SDL_NSAMPLES=38192 I get
18 seconds of smooth sound, 3/4 s garbled, 18 s smooth and so on ;).
That's something... I'll test it a little more. Thanks.

You can try setting QEMU_SDL_NSAMPLES environment variable. To 2048, 1024,
512 for instance. No guarantee though that it will help much.
