    Internal and External Microphone


    I want to control my external microphone as line in and keep built-in mic as one for calls.

    When i plug in my external mic the control passes to the external and the internal mic is not available. I want to control both these separately.

    I ham having Toshiba L750 with conexant driver.
    It has only one option in Recording devices even if i plug in external mic (as shown in the attachment).
    How can i get the line-in (External mic) as a separate option?


    Help me plssss
    Thanks in Advance

    You need the Microphone mode. The microphone mode provides 5VDC on the "ring" connection, which is required by a "computer" microphone. If you use or set the jack mode to "Line" the "ring" connector will change from 5VDC to a signal in connection and a "computer" microphone will not work.

    If you have an input jack, such as a "Line In" jack, it does not have the required 5 volts DC that is required by a computer microphone to work. Thus a computer microphone will not work plugging into the "Line In" jack.

    However, if your PC has an option to configure the Line In jack as a Microphone in jack then it can be used. In most cases it cannot be configured.
