strange sound behaviour in 0.8.27

27 July 2004, 20:09

Hi everybody!
On my PC sound emulation becomes scratchy, noisy & "skippy" after one-two minutes of gameplay. What's the reason? Quitting the emulator & restarting doesn't help either.
I didn't have this problem with older versions of Winuae.
Thanks in advance,
Dom

Tried to experiment with the sound buffer settings?
Sometimes it even helps to turn the slider a bit more to the LEFT!
(with some of my old setups, I had choppy sound with setting 4, but clean sound with setting 2!

)

Sorry for the bump, but I've recently been having similar problems with my sound. The CPU usage is only around 30% on all my configs (from A1000 -> A1200) but I still get strange scratchy sound no matter where I stick the slider in the sound buffer. Any suggestions ?

(BTW. I'm using the 1.3.1 version, I really should've started a new topic instead really but I'm not entirely sure when this problem arose)

I use setting 2 also and it works fine for me.

I only get good sound in all games with at a setting of 4 (at 44100 Hz).
However, a setting of 4 introduces quite some delay into the sound effects, which sucks. I mean, when I slash the sword in leander, the sound comes a bit too late. This is at 64% CPU usage. Now some games run fine with a setting of 2 or 3, but not all. All that at less than 100% cpu usage.

But I am using crappy VIA Chipset onboard sound.

I wonder what soundcard is the best to use with winuae? I mean which soundcard works fine with low delay? Any experience? Soundblaster live or audigy, maybe? Is it worth buying a soundcard? Does it make a difference?

BTW: Similar problem with delay/buffer in WinVice...

I have SB Live! Value, ages-old model (ca. 1999), works great still. Toni gave me a test prog and he said it had given excellent results. Now, what more can you expect

I'd better use the money saved by not buying an Audigy for a decent new gfx card

Great! With SB Live! Value, can you run WinUAE with buffer of 1 or 2 and not get scratchy/laggy sound? btw: is it possible to get sound in real dos (e.g. booting from win98 boot disk) with SB Live!?

Next WinUAE release has partly rewritten host-side sound code. May or may not fix some issues..

@rsn
Real DOS? Now, that's ages ago when I tested this

But yes, I think I had some DOS drivers for this card too.

[edit] BINGO!

About the buffer ... that is clearly dependent on both OS and CPU. With my old CPU (AthlonXP T-bird ~1 GHz), it worked better with "4" (Win98SE) resp. "3" (Windows 2000). Now, on Windows 2000, "2" works great, but takes some resources; i. e. nor is it possible to run too many apps at the same time when WinUAE is running; so if you do want to have lots of them running, live with some (minimum) sound delay issues, and go a bit higher with the buffer.

Note, sound is based on DirectSound (at least I reckon that it still is). DirectX too has improved a flipping lot in the last years, so comparisons are fairly hard to make.
