Microphone fails to unmute on visionOS device

[andriibilyanskii]

Describe the bug
On the visionOS device, the microphone fails to unmute. On the visionOS simulator and iOS device, all works.

SDK Version
2.11.0. But this bug was from the beginning app development (from v2.7.0). The latest version hasn't been tested on the devices yet, but in the releases section, I don't see a fix for it

iOS/macOS Version
macOS 15.7.4, visionOS 26.2, iOS 17.7.1

Xcode Version
26.2 (17C52)

Steps to Reproduce

try await room.localParticipant.setMicrophone(
  enabled: !room.localParticipant.isMicrophoneEnabled()
)

There is an image in a button, and it changes after pressing:

Button {
                        Task {
                            do {
                                try await room.localParticipant
                                    .setMicrophone(
                                        enabled: !room.localParticipant
                                            .isMicrophoneEnabled()
                                    )
                            } catch {
                                SentryService.sendMessage(
                                    "Failed to change microphone state: \(error)"
                                )
                            }
                        }
                    } label: {
                        Image(
                            systemName: room.localParticipant
                                .isMicrophoneEnabled()
                                ? "microphone.fill" : "microphone.slash.fill"
                        )
                    }

Expected behavior
The participant's microphone should turn on

@hiroshihorie does it seem reproducible on device?

@andriibilyanskii are you able to get any logs? e.g. from this error "Failed to change microphone state: \(error)"

[hiroshihorie]

@pblazej Unfortunately, I don't have the device near me at the moment.
@andriibilyanskii
Can you try with our example app ? https://github.com/livekit-examples/swift-example
And is your code throwing ? ☝️ what is the error ?

[pblazej]

Also, @andriibilyanskii spawning a new Task inside Button could be mitigated like that: https://github.com/livekit/components-swift/blob/main/Sources/LiveKitComponents/UI/Buttons/AsyncButton.swift

are you able to get any logs? e.g. from this error "Failed to change microphone state: \(error)"

@pblazej Unfortunately, not. I configured Sentry not to capture staging environment. But in next build it'll send logs

Can you try with our example app ? https://github.com/livekit-examples/swift-example

@hiroshihorie Yes, I've deployed a new build with this example app, so testers will test tomorrow

I deliberately look for what typical users won’t hit—boundary inputs, unusual flows, and stress conditions. That’s usually where the real issues live.

[andriibilyanskii]

Sorry for the long delay. The testers tested the LiveKit example, and everything works there. I also updated LiveKit to the 2.13.0 version on my project, and it works there too. They tested the old version, also via AsyncButton, and also the mute/unmute code from the demo project
