I'm assuming you do not want to hear the audio produced, hence the use of a null sink. load-module module-null-sink sink_name=null load-module module-combine sink_name=combine slaves=alsa_output.usb-Logitech_Logitech_G930_Headset-00-Headset.analog-stereo,null load-module module-loopback sink=null source=alsa_input.usb-Logitech_Logitech_G930_Headset-00-Headset.analog-mono Then you just set skype to use your null.monitor as for it's recording sink and the application you want to record should output o the combine sink. This setup ensures that Skype records the product of both what is playing on the combine sink and the mic. Of course this would be a lot easier if there was a module-combine-source, so patches welcome :D Col. -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mageia Contributor [http://www.mageia.org/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/]
