    Hi @wromRed,

    Thank you for choosing Photon!

    We are aware of the issue.
    Currently Bluetooth devices are not fully supported when using Photon microphone type.
    We are working on a fix.
    No ETA but we try to release an update asap.
  • hi @JohnTube i have fix this problem by setting DSP Buffer Size at first start
    AudioConfiguration _audioConfig = AudioSettings.GetConfiguration();
    _audioConfig.dspBufferSize = 1024;
    and now it can use bluetooth headphone (have test for android and ios ) hopefully it's can help someone have same issue like me

    Hi @wromRed,

    So you switched back to Unity microphone type I guess to make Bluetooth audio work...

    The no sound problem is probably due to:

    - Android permissions
    - clients not on the same room? (see matchmaking checklist)
    - some issue with the microphone? hardware or else?
    - some playback problem? hardware or else?

    Make sure to try on different devices.

    - i already get permission for android
    - client is in the same room
    - the problem is IOS user can hear what android user said but android can not
    - i have try with samsung galaxy note 10 and xiaomi mi 10

    Then maybe there is an issue in recording in iOS if it's not playback in Android.
    Did you enable microphone permission for iOS?
    See here.
  • hi @JohnTube yes i have enable micro permission for both Android & iOS
