I've been noticing some sound stuttering issues in two of the games I tested and decided to hit the ol' tab key and see if I could make any sense of what was going on... In Colony Wars, the game runs at 60fps dandy-like except for during the mission briefing/game loading/title screens, where it drops to 50fps for whatever reason. Since in game it runs at 60fps, the sound doesn't stutter, but unfortunatly the mission briefings sound like doodie Valkyrie Profile doesn't exhibit the same behavior, though the voices are scratchy and occasionaly it'll skip lines of text (this is just going through the introduction sequence). Finally, it's crashed on me a few times when trying to load a save state (let's face it, that intro crawls about the 20th time you watch it and backspace doesn't move it forward nearly fast enough). Saved a full memory dump thinking it's only be a few megs but it's actually 229...oops. I can still upload it to my website if you want it. Tried to enable -r to see if it made any difference, but it did not (in both cases). Going to go slowly go through my library and test out various problem children games (Metal Gear Solid, Chorno Cross, etc). On another forum, King Moo posted this: Also, on another forum, it's been observed that Final Fantasy Tactics' audio is grabled and distorted.

Hello, I know about the sound problems in FFT (the same thing happens with Xenogears). A workaround for this is to start the emulator with the -S option (note: it must be capital S...). eg: psxfin -S c:\mygames\fft.bin The same workaround may help other games. The reason there is no option in the config menus for this is that I was hoping to figure out WHY it happens and fix it I may add an option for the next version though if I don't get around to fixing it (this makes me sad though because I don't like options like that).

btw: if you encounter choppy/gappy sound in ALL games try increasing the sound latency... you should only do this if all games act the same though - other problems are probably compatibility bugs.

Ohh, forgot to mention that I tried bumping up the latency in various intervals for the games I'm getting the stuttering in and it had no positive effect (sometimes it'd wind up worse). Sorry for not including that in the original post. Been a long day Thanks for the heads up on FFT. I'll pass that on !

Yeah - setting it VERY high will probably have an adverse effect.
10-20ms should be about right (I think the default is 20ms).

Your computer might just be struggling a bit and that could be causing the stuttering. The sound code seems great for me though...even when a game is loading an intense sequence, it remains smooth as silk.

Hm, while we're still talking about the Sound options... I'll add a usability suggestion: can you make the latency textboxes editable (and move the sliders after the focus changes off the field)?

I also have sound stuttering except if I switch to full screen. Plus the BIOS runs really choppy in windowed mode, even though pSX only use like 20-25% CPU.
Specs: ASUS A7V333-X (using on-board audio), AMD Athlon XP 2000+ (Thoroughbred), 2x512MB RAM, ATi Radeon 9000 128MB.

I have the same problem while playing Mortal Kombat II. All voices and sound effects cut off. The music plays fine though. None of the suggested solutions have worked.
I'm running an AMD64 3500+ (32-bit version of WinXP), 1GB RAM, Radeon 9800 Pro w/ 256MB.
That aside, I love this new emulator. Keep up the great work.

The sound code seems great for me though...even when a game is loading an intense sequence, it remains smooth as silk. AthlonXP 2500+, 1gb PC2700, and my hard drive is a defragged SATA150. Motherboard is an MSI K7N2 Delta2-LSR (NForce2), using the onboard sound chipset (AC97) and latest audio drivers (just double checked to make sure) If anyone else could double check Colony Wars to verify the same behavior on their system, that'd be snappy. Also, does anyone else have the same problem with Valkyrie Profile (I know it crashes later, I just want to worry about one thing at a time though ) edit - just heard back from King Moo that the -S fix corrected Silent Hill's radio...but it breaks the music
