This is a quick update to earlier posts on Skype for interview audio. Skype on Linux remains a compelling alternative for recording interviews, especially given the high quality of the audio produced.
Skype 2.1 for Linux requires PulseAudio as as sound manager. Unfortunately this means that the crucial sound settings are scattered all over the map. Unfortunately the promising “PulseAudio Device Chooser” applet does not permit you to choose the current source of sound that the operating system (and therefore your applications) is paying attention to. For that, you’ll have to adjust the system sound preferences. Under the Input tab, select the appropriate device and adjust the gain.
Further bad news: I haven’t yet found an automatic switch that toggles back and forth to the headset microphone when you plug a headset in.
Further bad news: Skype doesn’t contain any settings to override PulseAudio in the GUI preferences / configuration. You’re stuck with PulseAudio for the time being.
