    Hi this is for those who suffer from the microphone issue. I finally stumbled upon a solution:

    if updating, rooting and changing mixer_paths did not work. Here is how you can fix it.

    First you need a rooted device.

    If you could, edit using a file explorer such as ES Explorer with root access

    /system/build.prop. Change




    Then, edit /system/etc/audio_platform_info.xml

    <device name="SND_DEVICE_IN_HANDSET_MIC" acdb_id="40" />


    <device name="SND_DEVICE_IN_HANDSET_MIC" acdb_id="4" />


    this is the reason why even flashing mixer_paths was useless. if required, i will be able to post links for the files involved in other to flash them.

    Yes, which issues are you referring to? And what exactly is it doing when we edit those lines?

    I've did some research and this should suppress the noice cancelling. In my case the problem that the other side can't hear me during a call (they can only hear me on speaker mode) is fixed when I put my finger on the other microphone (next to the camera), so I'll try this solution tomorrow.

    Has anyone else tried this solution? I've been having a problem with poor sound quality from the microphone in calls. The person I call complains that they can barely hear me. I've tried calling myself and I can confirm this. In my case I've also noticed that there's an echo whenever I said anything using the OPO. Seems like this could be due to the multiple microphones and a glitch in the noise-cancelling function.

    It did not solve my problems unfortunately. I can only still call properly when I put on speakermode.

    Thank you, kind citizen of OP. Here, I have procured 3 lovely ladies for a sacrifice in your honor. For those that try it, let us know how it goes.

    The solution here didn't work on its own. Now that I also modified the mixer-paths.xml, everything seems to work fine again.

    Hi, I have the problem too, where the other person can't hear me.
    I've modified my mixer-paths.xml and it helped (in some cases only apparently).
    Should I revert the mod, for this to work or should I be okay?

    Can someone tell me this? :/

    Hanness, Jan 3, 2015 :
    What do you mean exactly?

    In my case it seems to work when I did both the modifications in this thread and adapting the mixer-paths.xml. You can always try it and see what works best, the changes are easily reversible.

    You can just reflash "system" in fastboot. Is your bootloader unlocked?

    yea, it is :) How much will I wipe doing that? :p

    I'm on Lollipop btw., if that changes anything :)

    "Unable to mount system" - auch..
    How do I reflash "system" then?

    Edit: Fixed it by re-flashing my ROM..
    So, note to all: Don't do this on Lollipop - At least, if you did, do tell me how you solved it :)
