Audio session suspended when device is locked with Always-On-Display

[thomasbuitho]

What did you do?

I create a call (or join an existing one).
I lock the device (with Always-On-Display feature enabled).

What did you expect to happen?

I can keep going with my call (listening and speaking).

What happened instead?

Audio session seems to be fully suspended.
I can't listen to call anymore, neither speaking (orange dot from Dynamic Island turns off, also nobody can hear me from another device).

GetStream Environment

GetStream Video version: 1.38.1
GetStream Video frameworks: StreamVideo, StreamVideoSwiftUI
iOS version: iOS 26.0, iOS 26.1, iOS 26.2
Swift version: Swift 5.9
Xcode version: Xcode 26.2
Device: iPhone 17 Pro, iPhone 15 Pro Max

Additional context

1. Once device is unlocked, everything is back: audio session seems to be restored, no particular event is raised.
2. If application goes background before device being locked, everything is OK. Issue is only when locking device while application is foreground.
3. If Always-On-Display feature is disabled, everything is OK.
4. Issue is also visible with Stream Demo app.
5. Tested with built-in microphone and speaker, along with wireless headset: same result.
6. Stream SDK rollback tested: it seems to be working until v1.29.1 of Stream SDK (included), and KO since v1.30.0

Hey @thomasbuitho,

Thanks for reaching out. I just followed the steps you described above our DemoApp from develop, on an iPhone 14 Pro and i wasn't able to reproduce the issue. (i was able to talk and listen while the device was locked with the app in foreground and always-display-on enabled).

The only thing that rings a bell as potential issue, is that the Swift version you mention in your report is 5.9 while using Xcode 26.2 (which ships with 6.2.3). So either that version is wrong, or you are using a custom Swift toolchain that may be causing issues.

As i was unable to reproduce, I'm going to need some logs from you, in a call that the issue is reproducible. (Make sure to do LogConfig.level = .debug in your AppDelegate).

Best regards,
Ilias

Hello @ipavlidakis,

Thanks for your reply. I pulled your last changes from develop and tested again, same issue. I join a quick video along with logs for both devices used (iPhone 14 which works OK, iPhone 17 Pro which suspends audio session on device lock with AOD).

Indeed, details regarding Swift version needs more details: I use Xcode 26.2 with embedded Swift 6.2.3. However, by looking at Build settings from DemoApp, I see that target is configured to be compiled with Swift 5.

I doubled check configuration:
Xcode and embedded Swift version

$> xcrun swift --version
swift-driver version: 1.127.14.1 Apple Swift version 6.2.3 (swiftlang-6.2.3.3.21 clang-1700.6.3.2)
Target: arm64-apple-macosx26.0

DemoApp Xcode project configuration

$> xcodebuild -showBuildSettings | grep SWIFT_VERSION
SWIFT_VERSION = 5.0

$> grep -R "SWIFT_VERSION" *.xcodeproj
StreamVideo.xcodeproj/project.pbxproj:				SWIFT_VERSION = 5.0;
