**Description**  
I have an bluetooth device that is a speaker/mic combo and I have it connected to my iPhone. When I join a session, both the speaker and mic do not produce any sound nor does it pick up my voice. There is no audio coming the phone because I assume it is routing all audio to the bluetooth device. I have verified that the bluetooth device works as it works properly with the official Zoom app.

I have tested with the sample app provided with the VideoSDK and it also does not work. I have also included both bluetooth permissions “NSBluetoothPeripheralUsageDescription”, " NSBluetoothAlwaysUsageDescription" in the info.plist. I am curious what the purpose of these permissions are as I am never prompted with a dialog to allow these permissions from my device.

Without this bluetooth device connected, the phone’s speakers and mic work properly during a session.

Is there any additional configuration for audio required to get this to work?

**Which iOS Video SDK version?**  
1.5.2

**Smartphone (please complete the following information):**

- iPhone SE iOS15

Hi @curtis.forsta,

Video SDK as a SDK not care the audio output.  
Just provide the session audio.  
So, you can adjust the device audio output yourself by ‘`AVAudioSession`’.  
Please be careful of the availability version of AV api usage.

```auto
- (BOOL)overrideOutputAudioPort:(AVAudioSessionPortOverride)portOverride
						  error:(NSError **)outError
	API_AVAILABLE(ios(6.0), watchos(2.0), tvos(9.0)) API_UNAVAILABLE(macOS);

```

```
extern OSStatus
AudioSessionSetProperty(AudioSessionPropertyID inID,
						UInt32 inDataSize,
						const void *inData)                    
API_DEPRECATED("no longer supported", ios(2.0, 7.0), macCatalyst(14.0, 14.0)) API_UNAVAILABLE(macos) __WATCHOS_PROHIBITED__ TVOS_PROHIBITED;

```

```auto

```

@curtis.forsta  
It is working normally for me … what I do is to set the audio session as shown:

```auto
let avs = AVAudioSession.sharedInstance()
try? avs.setCategory(.playAndRecord, mode: .videoChat, options: .allowBluetooth)
try? avs.setActive(true)

```

Even if the docs are mentioning that `mode: .videoChat` should enable `options: .allowBluetooth` by default … I noticed in an early beta of iOS 16 that was not working so I’ve added it explicitly - that fixed the issue.

docs reference:

```auto
/** Only valid with kAudioSessionCategory_PlayAndRecord. Reduces the number of allowable audio
 routes to be only those that are appropriate for video chat applications. May engage appropriate
 system-supplied signal processing. Has the side effect of setting
 AVAudioSessionCategoryOptionAllowBluetooth and AVAudioSessionCategoryOptionDefaultToSpeaker. */
@available(iOS 7.0, *)
public static let videoChat: AVAudioSession.Mode

```
