Most likely a issue on your system.

 

Thus this is not a bug.

It could mean that the IRQ of the sound card is being shared with another Resource hogging device,

in my experience, its generally ok for a graphics card and sound card to share irq's with usb ports/devices, but if they share with eacth other, or with the System bus / ide bus, issues can occur

 

To be honest im not entirely sure, but if this just suddenly started occuring, i would suggest uninstalling the Dx Hotfix from Dec-January. I noticed Sonic3K.exe has jittery audio of late, and the only thing that changed was a few hotfixes. this stuttering, also fixed by lowering acceleration to basic, or using a software mdi ouput.

Most likely a issue on your system.

 

Thus this is not a bug.

 

I apologize since I didn't know where to post this, I wasn't sure if it was a bug or not.

 

What section would this be more appropriate in?

I suppose I can leave this in here, since it is a audio issue for you.

it might be good to get the latest sound drivers?

unless you consider volume, then OpenAL sounds louder [img]<fileStore.core_Emoticons>/emoticons/tongue.png[/img]/emoticons/tongue@2x.png 2x" width="20" height="20" />

 

I am sorry, but I really can't reproduce that. All three Audio APIs have the same volume for me.

@Xtreme2damax:

Have you tried increasing the buffer count for the OpenAL output yet?

Sound stuttering is usually caused when the sound buffers are not refilled until they all have played already, so increasing the buffer size should fix it.

If it doesn't, what speed does emulation run for you? Anything below 100% will naturally cause stuttering.

 

If none of these tips work, it is probably an issue related to your sound driver. I also have an OnBoard Realtek ALC889A (HD-Audio) chip and it is quite incompatible with OpenAL. When I play Unreal Tournament 3 with it, the 3D-Audio calculations are plain wrong and objects far away can be heard as if they're flying right above your head.

have you installed the latest Hotfixes though spacy?

I mentioned that decreasing sound acceleration solved my issues. It seems having it on full caused the emulator to stutter and thus the sound.

 

Turning down acceleration has improved everything for me and now everything is much smoother.

 

I don't know if it's alright to leave sound acceleration on basic. Should it cause problems leaving it on this level if I try to play a PC game or run another emulator?

 

Should I have anything to worry about leaving the sound acceleration on basic?

 

Thanks if anyone can let me know.

My WinXP has all the latest hotfixes.

as to openal being incompatible, afaik, most chips do OpenAL via EAX, so if openal sounds wrong, then its a bug in the EAX drivers, rather then openal itself, the only onboard solution that provides proper EAX is AD SoundMax, Realtek's drivers have never done so unfortunately.

 

XiFi is the only sound card to provide independant support for OpenAL.

 

X2DM, i think your issue is more likely a configuration issue then anything,

can you check the Windows System information (Accessories > System tools) and post what IRQ the sound is on?

 

Also, depending on your system type, it might even be a bug in APIC.
