What steps will reproduce the problem?
1. Start the game
2. Any sound it makes
3.

What is the expected output? What do you see instead?
The sounds that the game makes are not normal it sounds like a static TV
set whenever you hover over any button or when you get lines in the game.

What version of the product are you using? On what operating system?
1.2 RC7 Hubuntu Intrepid 8.10  2.6.27-11-generic

I recently upgraded one of my computers to Intrepid Ibex, I'll look into this.

Hmm, this one, I couldn't reproduce, though... Could you put the output of "cat
/dev/sndstat" here? Try experimenting with the options in System > Preferences >
Sound, maybe?

Does an older version of Quadra work right?

No reproduction information, I'll keep open, but we'll go ahead without this.

There is no /dev/sndstat on my system, and I found out online that this device 
file
is obsolete and without replacement. Is there another way to debug the sound ? 
Do you
need a strace ?

With the quadra sdl version the sound works fine, and also I have amarok 
running at
the same time, which doesn't work in quadra 1.2 because the device is busy.

I have the source code of quadra 1.1.8 and an old rpm from that version.
The source doesn't compile any more, maybe because it requires older libraries.
The rpm doesn't work either:

erreur: Dépendances requises:
        libpng.so.2 est nécessaire pour quadra-1.1.8-1.i386
        libstdc++-libc6.2-2.so.3 est nécessaire pour quadra-1.1.8-1.i386

And these versions of the libraries are no more available in my distribution
(OpenSUSE 11.1)

On my Ubuntu system, the /dev/sndstat is there, but is actually a symlink to
/proc/asound/oss/sndstat, which should be present on your system too (at least, 
once
the OSS/ALSA emulation module has been loaded).

It's quite possible that the OSS emulation has a "single opener" limitation, 
yes.

I think the library requirements of Quadra 1.1.8 are the same as 1.2.0 (the 
support
for Svgalib is in the older version, but should be optional), the problem is 
mainly
that the C++ code is not 100% standard-compliant, and as GCC was made
standard-compliant, some of the code constructs became illegal. I think you'd 
need a
GCC older than 3.0!

An strace would be very large, and probably not very helpful (too much to 
decode, and
some of the sound-related ioctls aren't formatted properly by strace), but 
compiling
with passing the "--enable-debug" option to "configure" will make Quadra output 
debug
information to stdout/stderr while running, those might be helpful.

I do have a feeling that the overall simplest way to fix this would be to 
release an
SDL version as quickly as possible. :-)

Thanks for helping out debug this!

Here's the debug log. But I didn't find anything related to sound in it.

The sound itself reminds me of past experience with 16-bit raw audio files 
where I
had to choose between little endian and big endian. If I chose the wrong one, it
sounded just like quadra does now. You might investigate that.

Quite right, not much useful in there relative to sound...

I did fix an endianness problem when making the SDL port, but it was only 
revealed to
me because I did this port on my Apple PowerBook, which has a PowerPC CPU, and 
that
the endianness of the CPU and of the sound card were different. I'm pretty sure 
that
on an x86, it should have worked fine? Strange...

I have the same sound issue. I am running archlinux on 64bit.

Running "padsp quadra" corrects the sound issue. I guess that means that 
pulseaudio's oss support is 
better than the alsa's oss emulation for quadra, or something of the like. I 
did try pasuspender first - it did 
not help the problem.

What version of Quadra was that for that last report (comment #11)? 1.1.8 or 
1.2.0?

Thanks!

Since using PulseAudio instead of ALSA fixed it, I'm guessing that this was 
some kind of issue in the system. I 
don't think it's realistic to expect me to go in there and debug this if I do 
not have reproduction, considering how 
little time I put on Quadra these days. If someone else comes up with a patch, 
send it in...
