 LineAdapter 
 // ... 
 let 
  
 request 
  
 = 
  
 GAMRequest 
 () 
 let 
  
 extras 
  
 = 
  
 GADMediationAdapterLineExtras 
 () 
 extras 
 . 
 adAudio 
  
 = 
  
 GADMediationAdapterLineAdAudio 
 . 
 unmuted 
 // ... 
 request 
 . 
 register 
 ( 
 extras 
 )

    Objective-C

      #import <LineAdapter/LineAdapter.h> 
 // ... 
 GAMRequest 
  
 * 
 request 
  
 = 
  
 [ 
 GAMRequest 
  
 request 
 ]; 
 GADMediationAdapterLineExtras 
  
 * 
 extras 
  
 = 
  
 [[ 
 GADMediationAdapterLineExtras 
  
 alloc 
 ] 
  
 init 
 ]; 
 extras 
 . 
 adAudio 
  
 = 
  
 GADMediationAdapterLineAdAudioUnmuted 
 ; 
 // ... 
 [ 
 request 
  
 registerAdNetworkExtras
