Noticable echo when speaker is on..

Bug description

A noticable (bothersome) echo is noticed when the caller has their speaker on for some odd reason. A simple disable speaker -> enable restores the balance in the call and after a couple of minutes the issue returns.

This issue has only been experienced where the receiving end is a S9+ and the callers device is a Note 20 Ultra.

Steps to reproduce

• Initiate a call between two parties.
• Have speaker on while the call is ongoing.
• Echo appears once again.

Actual result: Noticeable delay (30 ms?) which causes a form of echo in the call.
Expected result: Call to progress as expected without any echo or whatsoever.

Device info

Device: Manufacturer Model XVI
Android version: 13
Signal version: 6.17.3

No source file or test is named. Start by reproducing the call with speaker enabled on the listed Samsung devices and inspect the two linked debug logs; done means the recurring echo no longer occurs during the call.
