How audio streaming works
When the user is streaming audio to an Airtame device, the sound is automatically muted on the user’s machine so that it only comes from the display.
Note for Windows:
Attempting to unmute or adjust the volume will not have any effect on the received stream but may unmute the Windows PC resulting in audio clashing, where it sounds from two places at once at different times.
To adjust the volume, you must use the volume controls of the display that is receiving the stream.
Problems with displays - screens and projectors
Resolutions with/without audio support
Airtame takes the resolution that is preferred by the TV. In some cases, the detected resolution, might not support audio. This can be fixed by manually choosing the output resolution. For this, go to "Airtame settings" -> "Advanced Settings" -> "Resolution":
Now select the highest available resolution with audio, as shown below:
- (U) Unsupported resolution - means that Airtame did not get correct resolution list and had to use default ones.
- (P) Preferred mode: The screens preferred mode, may not include Audio
- (N) Non-standard Mode
- (C) CEA video standard
- (V) VESA video standard
Some screens and projectors, including Epson, have a setting called "Image Processing" which, when set to "Fine" can cause for audio to become out of sync with the video. Changing this setting to "Fast" will correct this issue.
Problems with Windows
There are two known issues when streaming sound on windows; One is 5.1 surround sound is not supported and the other is low-power consumption devices like notebooks and tablets.
Symptom: Audio continues to sound from the Computer at the same time as on the screen.
Some low powered devices (e.g. tablets) use hardware acceleration. In this case, the user must simply disable the audio hardware acceleration following the steps below:
- Right-click on the sound icon in your tray (bottom right), click Sounds and select the Playback tab
- Right-click the Playback device marked with Default Device and click on Properties
- Go to advanced tab in properties
- Disable hardware acceleration by unticking the box and apply changes
- In some cases you will need to change the "spatial sound" format to "off" or "Windows..."
Audio management software
Computers running audio management software, like Waves MaxxAudio or Nahimic may experience the audio to continue playing on the computer while doing an audio stream with Airtame.
The audio management software should be completely closed before the streaming session.
It is also recommended, for a permanent solution, to disable the Windows service running the aforementioned program:
- Press the windows key in the computer's keyboard
- Type "Services.msc"
- Right-click the correspondent service, i.e.: "Nahimic Service" or "Waves Audio Services"
- Click on "Stop"
- Right click again on the name of the service
- Click on "Properties"
- In the "Startup Type" option select "Disable"
- Click on "Apply"
