I am not familiar with those products. Sorry. All I can say about it is that there are 2 types of volumes. The ones for playback, and the ones for capture. (see F4 in alsa mixer). Also see F6 to select the right sound card if you have more than one. If you have more than one input (on that card), make sure you select the right one, You can toggle "capture" with space. Untoggle all of them, and leave on just the one you use for recording. Set the volume and try again. I hope it works. If not, maybe people on the forums could be of more help than I was. axl
