I had a similar problem and discovered that I had the Windows 'playback' and 'recording' properties of the VAC cables set to different sampling rates.

It sounds as if there's an echo on SSB. Here's my configuration: Flex 5000A with PowerSDR 2.3.5 running VAC 4.11. Computer is a Shuttle i7 running Windows 7 Ultimate. I have VAC 1 and 2 working in PowerSDR. I have disabled both and have the same results. Bose Companion 2 speakers are plugged directly in to the back of the Flex. I tried a different set of speakers and have the same problem. Even if I turn the computer system sound all the way down, I have the problem. If I look at the audio Volume Mixer in Windows I have one device, speakers, which is set for (speakers, Realtek High Definition Audio). I muted everything including the computer speakers and have the same problem. In the mixer window, I can see all 8 of my virtual audio cables plus a Realtek Digital Audio that are not selected. The applications that are present under the volume mixer window are System sounds, CommCat spot manager, Mozilla Firefox, and Flex Radio Systems PowerSDR. I know it's not RF because I get the audio feedback even with the amp off and power output set to zero. The only way to stop the feedback is to turn the Companion 2 speakers all the way down, or unplug them. What am I missing here?
