Is the microphone switched on in the playback controls [F3]? Is the volume set
to a reasonable level?
Switching on or off with "." (period or fullstop)
Mic can be off on playback but on on record to avoid feedback.
With [F4] you switch alsamixer to the capture controls. Capture should be
correctly on Mic because you are able to record your voice..
[F5] shows all controls
