    Line level audio not accepted as a "microphone" input


    I have an application that wants live speech input from a microphone.My system setup includes a preamp that raises the output of a headset microphone to standard line level.The program is looking only for a "microphone" input, and can not see my line level as an input.How can I get around this limitation?

    :)

  2. 5800: mic- or line-level input for recording audio?

    Considering purchasing the 5800... rather than using its inbuilt microphone, I want to attach an external microphone or line-level input to record audio... does this device have an appropriate input and recording functionality?

    Static microphone recoding doesn't accept any input - Windows 10

    Hi,

    Thank you for writing to Microsoft Community forum.

    • What is the model of the problematic Acer laptop?
    • Are you aware of any changes that happened on the computer prior to this issue?

    If the mic input on the PC is mono, plugging it into the
    Line In input of the sound card and selecting Line In as the
    Default Device, should resolve the issue.

    Note: Make sure the Line In device is not muted in
    Levels.

    If it is distortion, lowering the microphone level and raising the master volume of the computer will fix the issue.

    Meanwhile, I suggest you to try the troubleshooting steps listed in
    Fix microphone problems and check if it works.

    If the issue persists, update the BIOS, as this could also happen due to outdated BIOS. I recommend you to get in touch with the Acer support and get the latest version of BIOS installed.

    Note:

    Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from
    the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

    Let us know how it goes.

    Regards,

  4. Line level audio not accepted as a "microphone" input

    Combo Input Changed from Mic to Line In: Can't revert to Microphone

    Hi,

    I have an Windows 10 HP Desktop (product # Y1B39AV) which has builtin sound (i.e. no sound card). It has only 2 audio jacks on the back labeled with icons. One appears to be output and is plugged into my speakers, which work fine. The other appears to be input and is plugged into a microphone which used to work but now doesn't. (There are also 2 output jacks on the front labeled with icons: 1 appears to be for a headphone and the other for a headphone with a mic. They both work when I plug a headphone in.) I also have a Logitech C310 Webcam which plugs into a USB port and works fine for both sound and video. All of this has been connected and working correctly for over a year.

    My problem is that my microphone no longer works. When I use Audacity to record from the mic I previously selected Microphone (Synaptics HD Audio) but now that's been replaced with Line In (Synaptics HD Audio). When I record from that I get very faint sound.

    It seems that my PC previously thought that the input jack on the back was a mic input but now it thinks it's a line in input. As I recall when I first plugged the microphone in I was prompted to select what type of device I had plugged in, either Line In or Microphone, and I picked Microphone. That worked fine until the PC decided for unknown reasons that it's a Line In device. Since the Line In inputs expect 40 to 60 dBV higher levels than the Microphone level the microphone input sound is so low as to be useless.

    The problem is I don't know how to switch that input jack back to Microphone from Line In. I don't see it in the HP documentation or anywhere else. Everywhere I look in Windows (Device Manager, Settings for Sound) it just shows the Synaptics Line In input (and also the Webcam mic) and there's no Synaptics Microphone anywhere. Under Settings/Sound/Manage Devices there is a Synaptics Stereo Audio input that's disabled but when I enable it and record from it in Audacity (called Stereo Mix there) there's no sound at all. Nowhere do I see a Synaptics Microphone.

    Can anyone tell how to fix this? I'm running Windows 10 ver. 1903.

    Thanks,
    Mike

    Further research on the HP web site reveals that this input port is "re-taskable" as a Line-in or Microphone-in port. However so far that hasn't helped me figure out how to re-task it.
