I find that when playing Amiga games in WinUAE, the sound goes choppy for no apparent reason. Sometimes this happens right away when starting emulation, other times sound is fine for a while then starts to go choppy at some apparently random point. Is there anything that can be done to prevent this from happening?

My system:

  • Windows XP SP 3.
  • AMD Athlon 64 X2 Dual Core Processor 4400+, 1.98GB RAM, NVIDIA GeForce 6100 nForce 405.

Some more details:

  • I am using version 2.3.2.0, but have also tried 2.4.1 and had the same result.
  • I've changed settings, such as sound buffer settings - but this doesn't appear to help.
  • The problem appears to happen with any game - not just a specific game.
  • The SND: value at the bottom of the WinUAE window often goes negative and is sometimes greyed-out. What does this mean?
  • I don't have any sound issues when using other non-WinUAE software on the same PC.

WinUAE uses the QueryPerformanceCounter function for timing, and it may be inaccurate on some systems as described here.

I may not have the answer you are looking for exactly, but I will try to help. I had choppy sounds with some games and I tried a lot tweaking before. Some games and demos were really difficult to get to work 100% soundwise.

Later I activated the F12 WinUAE menu from the Option Tab. This means I can use F12 to go to the detailed tweaking screen and test all the options quickly. When I go to Settings - Host - Sound and change the first option, for me it said DSOUND Primary Sound Driver and then Realtek. I have an old Acer with no graphics card and 2GB memory, a dual core 2.1Ghz Cpu. Now I got games like Awesome running perfectly even soundwise.

I still get choppy sounds though, when I multitask, but I don't mind that.
