  • Bluetooth phone audio issue

    I don't know what sub forum to put this in.

    But here's the question I have about using the computer as a hands free phone device. (Don't worry I'm not going to ask another question about how to get Phone Control to work. I gave up with that.)

    I basically have the computer working as a very simple headset. I still have to use the phone pick up and dial calls, but the audio comes through the car speakers. This software came with my bluetooth dongle.

    Here's the problem...

    The microphone I have picks up the audio of the car speakers. So while everything works great for me, the person I'm talking to and hear their voice fed back to them (like when you call a radio station and don't turn your sound down)

    Is there a way to set this up physically to prevent or diminish this?

    Or even better a software solution?

    Unfortunately I don't think there is a lot you can do. I don't know of any software workaround.

    The mic is doing what it is designed for. You could turn the speaker volume down, but in all honesty if you turned it low enough for the mic not to pick it up then I doubt you would hear it either.

    What is needed is a noise cancelling mic, one where the sensitivity is adjustable. Then is is a case of balancing the speaker volume and mic sensitivity.

      That's okay. As soon as I posted this suddenly the audio doesn't work with the blue tooth at all.

      Now when I have the blue tooth connected to the CarPC the phone will automatically answer itself and I can't hear the audio on the speakers.

      All out of no where.

      Go figure.

        Sort of fixed the first problem. (It's a trial and error thing I've decided and it's just going to take a while to position the mic and adjust teh volume properties so that it's not picking up the speaker noise.)

        But here's the latest problem I've notice with this set up.

        The phone (Motoroloa RAZR V3t) will only work with the computer's audio system once per power cycle.

        Meaning that it'll work just fine. I'll hear the sound over the car speakers like I'm supposed to....until I disconnect the signal at the computer. Once I turn off the CarPC and turn it back on, the phone will still connect, but I'll no longer hear any audio until I turn the phone off and turn it back on.

        All I get is silence. Not even the speaker on the phone will work. But if I disconnect the bluetooth the phone works fine as a normal phone.

        So I'm stuck with having to cycle the power of the phone every time I get in the car to make this set up work.

        My instincts tell me this is a phone issue not a computer issue. But I'm not sure.

        Any thoughts on how to correct this?
