Samsung R700-Aura T5750 NP-R700 Acoustic Echo Cancellation, Acoustic Echo Cancellation, QI cannot hear my voice through the built-inmicrophone

QI cannot hear my voice through the built-in microphone.

AThis is because the setting is configured so that sound from the built-in microphone to the speaker is muted to reduce the howling sound effect. You can use the microphone recording function normally, even in this state.

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.

QI have a trouble with recording after selecting ‘Acoustic Echo Cancellation’ and unselecting Mute in the Microphone volume of the Playback Mixer.

AThis is because the sound from the external microphone is muted by the Acoustic Echo Cancellation Algorithm considering the sound as a Acoustic Echo while the recording and playing back is processed at the same time. In this case, select Mute in the

Microphone Volume of the Playback

Mixer after selecting Acoustic Echo Cancellation item.
