Hi Developers, Thanks for your hard work.
I have an issue with an android build that I am using and intend to do small
scale testing (10 users) over the next 10 days.
Problem description:
Outgoing calls from my device (Device 1) do not work as they have no audio in
ether direction. Note: video does show in both directions
Expected functionality:
Audio and video works in both call directions.
Environment:
Device 1 is a Android Tv based on Android 9 with a custom build of the Linphone
android app based on build:
Device 2 is an iOS Phone with current App Store build.
Core has not been modified only app level modification for TV use and USB
WebCam have been made
Process:
If the iOS phone (device 2) calls the Tv (device 1) the call connects and
video is shown but no audio can be heard in both directions
If the android TV (device 1) calls the iOS phone (device 2) the call connects
and video can be seen but no no audio is heard in ether direction.
Testing so far:
I have tried looking at the logs (attached) but can not see the obvious issue
with the audio.
I have tried placing a call from the iOS phone (Device 2) to the TV (device1)
after the call audio issue and the call connects correctly and audio is present
so I assume that it is not a call state issue but more likely a codex or
negotiation issue.
In a failed audio call I have tried muting / unmuting the audio on both ends
and stopping and restarting the video in case this will cause a stuck process
to restart
Additional logs messages have be added around audio route helper in the app to
see if this will reveal the issue.
Logs:
Attached logs are from Device 1 the TV
Log 1 is start-up through successful incoming call from iOS phone (device 2) to
TV (device 1) with working audio
Log 2 is the following log with a failed call from the TV (device 1) to the iOS
phone (device 2) all the way to call termination (note no extra button press
etc )
Please take a look at the logs and give me some feedback as soon as you can.
Thanks,
Andy
