When I record screencasts on my laptop with USB headphones, the audio increasingly lags behind the video.
However when I record with my built-in laptop microphone, there is no lag.
I have tried recording with both Camtasia as well as Hypercam 2, each give the same results.
I have tried 3 different USB headphones, each give the same results. All USB headphones are made by Plantronics.
I unfortunately have no microphone audio jack on my laptop (only a headphone jack) so cannot test non-USB headphones.
I also downloaded the 32-bit version of Hypercam instead of the 64-bit version, with same results.
My laptop is:
- Dell Latitude E6420
- Windows 7, 64-bit
- Intel Core i5-2520M CPU @ 2.50GHz
- 8 GB
What could be causing this lag to occur when recording with USB headphones and how do I fix it?
