A machine can have more than one sound device. A PCI sound card and a USB headset for example. Skype allows devices to be chosen in Tools > Options > Sound Devices. Nothing similar is evident in iceweasel > Edit > Preferences nor in xine > Audio. How is a sound device selected in Iceweasel and in Xine? Thanks, Peter E.
