1.0: Screech-Squeal sound issue with XAudio + RealtekHD on Vista
by TheGasMan · in Torque 3D Professional · 09/29/2009 (1:24 am) · 22 replies
This scenario either ends with a high pitch squeal or with the looping sounds becoming ignored...
Squeal:
If I turn on some or all of the sounds in the Burg level..then switch from Xaudio to directsound and back to Xaudio: I get a high pitch squeal/buzz sound. This sound *issue is not there at level start with Xaudio. It only happens after switching from and back to the Xaudio preference.
Looping ceases:
If I do the same in the PhysX demo(after adding in a looping sound emitter), when I return to Xaudio, the loop ceases(If I reselect DirectSound, the loop is back). My weapon sounds are fine at that point..but the loops are no longer playing. To get the loop back to 'on' for Xaudio: I have to open the editor, select the speaker and double click the profile setting(in essence: I reselect the profile) to have the sound play with 'looping' once again.
///
here is an mp3 recording of switching back an forth between DirectSound and the Xaudio Squeal : Here (done through a mic)
**WARNING** the sound file is annoying and could hurt your hearing if your speakers/headphones are too loud. Also has the ability to seriously piss people off.**
///
Any one else getting this behavior ?
P.S. We need a version 1.0 bug Tag for the forums. :P

People with the demo of T3D have this "Squeal" issue as well. ..I think the point is made.

I tested this by starting out in xaudio, then switching to direct sound. Upon doing this, the sound quality deteriorated.. but was still working. When I switched back to xaudio, all sound stopped, and a high frequency squeal began and didn't stop.
As stated above, I use Realtekac97. (on xp)
Hope this helps.
