android: incoming call audio comes into wrong stream

[WhitePhoera]

when i recieve call(i have autoanswer) sound comes into Stream.Ring(or notification). (into speaker and volume controled by ring stream) in Listener.OnCallStateChanged i have: `
private void OnCall(Core lc, Call lcall, Linphone.CallState state, string message)

    {

        if (state == Linphone.CallState.IncomingReceived)

        {

                    lcall.Accept();

        }

    }

` if i do outgoing call sound comes into correct stream with correct volume handling.

if i set AudioManager.Mode = Mode.InCommunication then sound comes into ear speaker. but stream volume still controled by Ring stream volume.

tested on latest Xamarin sdk(loaded today, not nightly). any idea how to fix it?

seems native libraries from same android sdk don't have that issue.

Which audio stream is used is decided by the library. If the ring card is being used, then the Android RING stream is chosen. When a call is connected, the playcard is set to use the VOICE stream. This is true for both OpenSLES and Android media soundcard. Are you using on of those two ?

Maybe your issue is related to the fact you have enabled the auto answer. Have you tried to disable it ?

i may return to Xamarin packed aar file and try again.

but issue just was solved by replacing aar from android-java package. so, looks like it's just present in that version of aar.

by fact i need autoanswer, since when i start SIP user already notified and accepted connection(via push) i set

                LinphoneCore.Ring = null;
                LinphoneCore.Ringback = null;
                LinphoneCore.RemoteRingbackTone = null;
                LinphoneCore.RingDuringIncomingEarlyMedia = false;
                LinphoneCore.RingerDevice = null;

since i don't need ringer from linphone.

still issue persist, it sometimes uses media stream, sometimes uses ringer one, sometimes all ok. i use default sound device, do i need specify specific to work correctly? (i tryed set delay, but no changes)

also just found that somehow i have no sound output on android 8.

2018-03-23 14:20:35:240 mediastreamer-warning-Not enough ref samples, using zeroes
2018-03-23 14:20:35:258 mediastreamer-message-Samples are back.
2018-03-23 14:20:35:309 mediastreamer-warning-Too many samples to drop, dropping entire frame.

looped in logs

i just also got report that notification also switches sound to loud-speaker and there is no way to disable it unless restart call.

[WhitePhoera]

also on such phones if i try to enable speaker sound will disappear.

may be for me will be better use Java-android version and just wrap it?

[WhitePhoera]

I wanna summarize: Can i disable auto stream selection? I just need voice one. All routing/mode i will do myself.(loudspeaker, phone speaker, bt/sco) I need it just do input/output. No additional reaction for focus and etc.(no reaction for notification and etc)

[WhitePhoera]

any info? it sometimes loses audio when i do

Audio.SpeakerphoneOn = true

on some phones at least.(one for sure with Android 8.1)

or if any notification with sound will arrive

Hi, I don't need ringer too, and I set LinphoneCore just like you, can you disable ring after you set these? Here is my question. https://github.com/BelledonneCommunications/linphone-android/issues/498
