![]() Although we've only gone to WC 6.x, 7.x versions and Desktop Video 10.6.x, 10.7.x and 10.8. Rolling around Desktop Video drivers and Wirecast versions has not made a difference. The error may happen 15 minutes into a stream, 60 minutes, or it (very rarely) will not occur within a 60 minute broascast/record at all. BlackMagic Design drivers, we recommend only installing Desktop Video 10.8.4. One test that I have not ran, which I am currently running as I write this post, is to set all of my encodes, whether it be record-to-disk or live stream, to have an audio sample rate of 48KHz instead of 44.1KHz. Its not that we need 4K, but Id like to make sure we can use this card. What I believe is happening is there is some type of wordclock type issue between the Intensity card (which samples at 48KHz) and Wirecast (which, in all of my output settings, encodes at 44.1KHz). ![]() The early signs of this audio issue (with the same hardware) came about over a year ago when the PC was on Windows 7 and upgraded to WC 6.x.x. I've seen direct posts on the exact hardware with the exact issues but forum-wise, there is not a publicly posted remedy or legitimate cause.

The issue had been existent in the past but in a slightly different flavor, where the noise introduced was a little different and there was a ping-pong stereo effect. While encoding, audio will suddenly randomly ramp up some digital distortion/sampling error noise, then the audio is bit crushed and distorted and maintains like this. Always install the original drivers supplied with your BlackMagic Intensity Pro card first and then test as previously noted before.
