<![CDATA[Caller echo]]>Hi. When i call, sound is good for me (level a little too low), but people i talk to have an echo really unpleasant.
I have read few topics about that but i am not able to fix this.
Do you know if this is my phone or a bug with ubports? Does someone have an idea how to fix it?

I find using earbuds seems to solve the problem... ymmv.

Can this solution also be implemented for the OP3(T)? Or was there already another solution here. Thanks.

I decided to return Android for now, restored backup of all partitions through TWRP, loaded Android, and decided to try this case, will this "echo" under Android. There is no echo, the caller not hear himself, even when this phonecase on the phone. BTW, some kind of problem with echo cancellation under UT!

The workaround was to turn off AEC (Acoustic Echo Cancellation) and NS (Noise Suppression) in the "vendor" stuff.
For example this link:
https://forum.xda-developers.com/t/the-echo-issue.3793902/
We have in Redmi Note 7, also this set of mechanisms in sound preprocessing, with the same UUIDs
I quote the file /vendor/etc/audio_effects.xml

    <preprocess>
        <stream type="voice_communication">
            <apply effect="aec"/>
            <apply effect="ns"/>
        </stream>
    </preprocess>

Maybe this solution could help?

I really like ubports, and use only this... But embarrassing when people say they hear themselves... Do you thing that formating the phone and resinstall everything could help?

  1. setprop persist.audio.fluence.voicecall false, both under root & phablet
  2. uVolMan, both: Main microphone volume, and Audio property:
    sink-input-by-media-role:phone
    nothing helps....

sound is good for me (level a little too low)

For this problem, maybe you can solve it with uVolMan.
For the echo i have no clue.
