Re: [OpenSIPStack] Vista Sound Problem

[Whit T. <de...@wh...>]

I know this thread is kind of old.. but I thought I'd add the specific 
reference for this issue:

        7.16 - Why am I getting broken audio under Windows Vista?

The sound drivers in Windows Vista require more buffers than identical 
hardware under Windows XP or Linux. If you are getting broken audio, try 
increasing the number of sound buffers to 8 or 10.

Simpleopal does this by default. Other Opal-based software can do this 
by adding the following code to the initialisation of the PCSS endpoint:

  pcssEP->SetSoundChannelBufferDepth(10);

"


I'm currently testing ATLSIP with Vista. I'll let you know if there are 
any other tricks/tips for any other issues encountered.

Regards,

Whit
