http://ubuntuforums.org – hello there Ive bought i new webcam, Hercules Dualpix Exchange, i've tested on SKype, but there is no sound, althought the webcam has his own microphone. I've saw in the options of Skype that for the sounds device for the microphone, he uses PulseAudio server (i dont have any idea what that means). then in the volume controle, as device i found my webcam 2 times :), one as Alsa mixer, and the other "Capture: Hercules Dualpix Exchange - USB Audio (PulseAudio)". But every time i try to change the parameters of these device, after i close the window, the next time, my changes arnt done. Do anyone have an idea wath shoul i do?? (Hardware)
