recordMyDesktop works o.k. -- captures both video and audio and synchronizes the two.
However, the audio is poor quality -- loud hissing and about half the volume of the original.
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

Is the problem that I have a cheap sound card? Or is there something that can be done to improve the quality of the audio recording?
