[Stella-devel] Static in sound with workaround

[Justin C. <jch...@gm...>]

Hey Guys,

I've noticed a loud static sound in all games (only tested in 3.0.0
and 3.1.2). Changing various audio settings in the sound dialog
changes the sound of the static but never eliminates it. It's so loud
you can barely hear the effects from the games.
I did some searching and found that there have been scattered reports
of the same thing from time to time as well.

I decided to mess around with the code a bit and found that making the
change below (attached) completely eliminates the static and sound
seems to work fine.

Obviously switching from unsigned 8bit to unsigned 16bit fixes the
issue on my system, but as I'm not familiar with SDL I'm really not
sure why that is, or why it would be required on my system.

Here are the details on my system:

Gentoo Linux 64bit
2.6.33 SMP kernel
Phenom II X2 550
Creative SBLive (03:07.0 Multimedia audio controller: Creative Labs SB
Live! EMU10k1 (rev 04))
Gefore 8800 GTS (01:00.0 VGA compatible controller: nVidia Corporation
G80 [GeForce 8800 GTS] (rev a2))

gcc-4.3.4
libSDL-1.2.13
alsa-1.0.20

Hope this helps. If there's any more information I can provide or
patches I can test I'd be more than happy to help.

Thanks for the great emulator!

Justin
