call audio

[Xerxes 8933A/A]

The call audio is too bad to understand.  Broken mechanical static.  It is bad
for both incoming and outgoing calls.  I've tried the sound settings for the phone 
but nothing makes a difference.  Any clues?

I'm pretty sure the speaker at the top and the one at the back are seperate.

I just received my postmarket os 3gig model pinephone and all is well except the call audio is incomprehensible.

I haven't opened it up yet but thats about to happen... to see if I can notice anything obviously wrong with the speaker.

The rear speaker works for ring / music / website audio,  but making a call the top ear speaker outputs nothing but garbage.

Very static.  Sounds like the speak is blown, or maybe crushed.
