@bkervaski Can you confirm you do not reproduce this issue with 6.0.12 and 7.0.0-RC3 ?

[bkervaski]

With 6.0.12 it's working fine, but with 7.0.0 and 8.0.0 it seems the library is setting the AVAudioSession AVAudioSessionPortOverride on it's own terms, not honoring the default state or any state changes. When you terminate a session, it always leaves AVAudioSessionPortOverrideSpeaker. Hope this helps!

Thank you, I think the issue is on master and incoming 6.0.13, since 7.00 and 8.00 has merged master the issue also occur, possibly due to this changes c49bdc5#diff-59c7d02174607ded42b5b45bc22f8b06

Can you test this 2 version and tell me if you have the issue, it will help to confirm what changes introduced the behavior changes.

• 15402b1

Example with 15402b1:

cordova plugin remove cordova-plugin-iosrtc --verbose
cordova plugin add https://github.com/cordova-rtc/cordova-plugin-iosrtc#15402b1 --verbose
cordova platform remove ios --no-save
cordova platform add ios --no-save

Both 995eaaf and 15402b1 work the same as 6.0.12.

I re-tested 7.0.0 and 8.0.0, both have the issue.

One thing that is noticeably different, 7.0.0 and 8.0.0 both initialize the audio for the app in ambient mode, where all the regular audio (i.e., Audio().play() or AudioContext audio) are lower volume than should be until the first call, then the audio is at a normal level.

Hope this helps :)

I also tested with 6.0.13 and this version works like 6.0.12 and does not exhibit the behavior as 7.0.0 and 8.0.0.

Thank you this help a lot.

[hthetiot]

Please test #task/7.0.0 or 7.0.0-RC4

[hthetiot]

Is that related #486, I wonder.

[bkervaski]

I tested 7.0.0-RC4 and the same result. I then added cordova-plugin-nativeaudio just to see if I could hack around the issue.

What happens is on initial app startup, the volume is low (ambient) and then at the end of the first ios-rtc call the volume is unpredictable based on what happened before the first ios-rtc call.

For example, if I play a nativeaudio loop, it plays at non-ambient (normal) sound levels. Then, after the first call, all audio (including the loop) are back to ambient (low volume).

If I create an AudioContext and say generate some sounds, on app launch it's ambient. After the first ios-rtc call, it's now normal.

On 6.0.13 I can overcome this by simply playing a silent mp3 file on app launch, seems to work. But 6.0.13 has the ontrack() bug, so I have to use the later versions.

Is it possible to just disable all audio control in ios-rtc, at least as an option, so we can simply set the state elsewhere and not let ios-rtc manipulate that state?

Anyway, hope this helps :)

Yes via MANUAL_INIT_AUDIO_DEVICE (#503) that is part of 6.0.13, when you install the MANUAL_INIT_AUDIO_DEVICE value willl be false by default.

Is that what you looking for @bkervaski ?

I also realize that we enforce the output here but we do not restore it on Peer or Media/Track Close for example.

But 6.0.13 has the ontrack() bug, so I have to use the later versions.

@bkervaski ontrack() bug should be fixed on master and on 6.0.13-RC2 do you mind testing again with MANUAL_INIT_AUDIO_DEVICE and 6.0.13 (confirm if ontrack fixed).

[hthetiot]

@bkervaski can you test 6.0.16 and if still not fixed comment to reopen. See previous comments for fix master and releases.

Hello here,
the audio is still low volume at the end of a session and is ducking all other apps volume until we hard quit the app.
Thanks for your initial post @bkervaski
I tried to

    cordova.plugins.iosrtc.selectAudioOutput("speaker")
    cordova.plugins.iosrtc.turnOnSpeaker(true);
    cordova.plugins.iosrtc.initAudioDevices()

not helping, I remember previously in6.0.12 all was ok back then.
I even downgraded because of this precisely.

[numerized]

I'm on IOSRTC 8, I'll now try 6.0.16

[numerized]

yeah I confirm the audio is still low volume at the end of a session on 6.0.16
I'm now going to try with 6.0.12
