adjusting volume while recording audio playback and microphone

[ben22]

Hiya,

In short:
how can I adjust the volume level while recording audio playback and microphone at the same time? I managed to increase the audio playback volume with PulseAudio Volume Control (Input devices -> Monitor of Internal Audio Analog Stereo -> pressing green button "Set as fallback"), but once I click on that green button, no no microphone sound is recorded.

Details:
- using Ubuntu 10.04 LTS
- recording audio with Sound Recorder
- installed PulseAudio Device Choooser and PulseAudio Volume Control
- Input devices -> Internal Audio Analog Stereo --> shows the sound from microphone
- Input devices -> Monitor of Internal Audio Analog Stereo --> shows sound from audioplayback

- Input devices -> Monitor of Internal Audio Analog Stereo -> I press green button "Set as fallback"--> audio playback recorded, but no microphone sound
- Input devices -> Internal Audio Analog Stereo -> I press green button "Set as fallback"--> microphone sound, but no audio playback.


Question:
- how to adjust volume of audioplayback and microphone recording and record both as a mix together? Thanks!

PS: I checked out this thread, but haven't figured out how to adjust the volumes.

I tried the following:
- Set it to get to the point where it will record from your sound card.
- Then press Alt-F2 and enter "cvlc alsa://hw:0,0".
- I hear my own voice via the headphones, but it is not recorded with the audio playback and another gnome-sound-recorder is opened and I get error "No file name specified for writing"

any suggestions?

Is there any way you could send me an audio file that can show me what's going wrong? Preferably a downloadable one (or embedded in a YouTube video or some other streamable service) as I am currently occupied with something else and unable to log onto a chat client at the moment.
