Describe the bug

On some devices, LiveKit doesn't select audio device in PreJoin (nor inside call) even though LiveKit sees several audio devices. Camera is selected correctly. After joining call, the sound is transmitted correctly, but in MediaSelectDevice there is still nothing selected

const audioDevices = useMediaDevices({ kind: 'audioinput' })
console.log('audioDevices length:', audioDevices.length) // audioDevices length: 2

console.log(userChoices.audioDeviceId) // ''
console.log(userChoices.videoDeviceId) // 'abc123def...'

it happens on https://meet.livekit.io as well

would it be possible for you to check whether https://github.com/livekit/components-js/pull/952 fixes the issue for you?

@lukasIO same issue with latest build, audio device is showing as selected but its not really selected and require a re-selection for audio to be transmitted. I'm on iPhone 13pro iOS 18

I'm running into a similar issue where trying to change the microphone or camera on the prejoin screen doesn't update every time. No error is being thrown but it just doesn't update.

I think something is going wrong in the setActiveMediaDevice function.

thanks for your patience on this. We applied some changes recently to improve the situation with device handling across our SDKs. Feel free to open a new issue if you're still running into problems with this
