Pixel 4XL (coral) - No call sound

[Sharon]

Hi All

I built AOSP 10 from source according to Google documentation, including the binaries that match the version of AOSP

no cherry picks, no code changes only Vanilla AOSP - but no in-call audio 

What I did:

repo init -u https://android.googlesource.com/platform/manifest -b android-10.0.0_r31

pull and extract google drivers and qcom from here - https://developers.google.com/android/drivers#coralqq2a.200305.003

Anyone knows the fix or can point me to files that could fix it

thanks!

I found a suspicious line in the logcat:

hardware_info: hw_info_append_hw_type : device_name = vi-feedback

Is it an 'audio loopback'?
