    Yes this is occurring with me also.
    The other party cannot understand me - voice on regular calling is unintelligible.
    Other voice applications (e.g. Google Duo are fine).
    This is a phone (6T) purchased from Oneplus on T-Mobile network upgraded to Android 10 open beta. I've tried disabling VOLTE and VOWiFi but nothing fixed the problem.

    On another forum, the fix was given as turning on/off the speaker function on a call. I tried this and it worked.

    When you make a call, there's the ability to use the speaker (speaker icon)

    You don't have to keep it on, you just need to toggle it. (and I think it's just once ... maybe after reboot but I don't know)

    For anyone finding this in a search, I just had this identical problem with the Android 10 "final" release for my 5t... and the suggestion of toggling the "speakerphone" button on and off works great! :)

    As an additional detail, people on the other end of the call heard me fine - but all I could hear was something like an insect buzzing - very much like the old Star Trek episode with the civilization running at greatly increased speed. ;)

    Note that this [apparently] only has to be done once after the update - the "fix" sticks.

    I have 6t with 10.3.4 OS and also have bad quality call sound on my earpiece.
    I tried the toggle mode, but nothing changed.
    I also hard reset the phone...
    I didn't pay attention to it, but I believe after the update to 10.3.4 OS started this.
    Any other suggestions?

    Do a Full Factory Reset

    This will restore you to a fresh installation of Android. So you will need to backup your phone.

    After Backing up the phone.

    Go to Settings,
    Reset Options,
    Enable Erase Internal Storage.

    Then click on the Delete All Data button.

    Once done, use the phone for a couple of days without adding apps to check for issues with just the raw fresh OOS only.

    Only introduce previous 3rd party apps gradually over 2 weeks to see if any particular app or apps drain the battery

    For more info on how to backup your phone, check the solutions here.

    I did a hard reset last week or so already, sound is the same. Checked with SIM from another provider, on Facebook messenger and what's app voice call. I will do another hard reset tommorow, but I tend to believe that the earpiece is broken. So I will send it for warranty.
