Q
I cannot hear my voice with the
internal microphone.
A This is because the sound from the
internal microphone is removed so
that the sound is not delivered to the
speaker and causes feedback from
the internal microphone. However,
you can record the sound from the
microphone normally.
► For Windows 7
When using an external microphone,
select the Play Device > Speaker
> Level
tab and deselect Mute
for the Microphone. Then you can
listen to the sound from the external
microphone through the speakers.
► For Windows XP
When using an external microphone,
if you disable the microphone channel
mute function of the play mixer, you
can hear the sound input into the
external microphone through the
speaker.
