Audio Playout & Monitoring Walkthrough

This update enhances HighAsCG with “CasparCG Enhanced” features, specifically focusing on PortAudio support, multi-channel layouts (8ch/16ch), and hardware-level monitoring.

1. PortAudio Output Setup

You can now assign physical audio outputs to your GPU (DP/HDMI) ports or dedicated audio cards.

1. Open Device View.
2. Click on a GPU or Audio port.
3. In the inspector:
   • Check Enable PortAudio.
   • Select the physical Device from the dropdown (e.g., NVidia HDMI 0).
   • Choose the Layout (Stereo, 4ch, 8ch, 16ch).
   • Save Audio Settings.

2. Channel Patching (Cross-Patching)

If you need to route specific internal CasparCG channels to different physical outputs:

1. In the same Audio Inspector, use the Pair Mapper.
2. Example: To send internal channels Mix 7-8 to physical Out 1-2:
   • Set Out 1-2 ← Mix 7-8.
3. Click Save Audio Settings.
4. Apply the Caspar configuration (Settings → Apply).

[!TIP] In your Timeline or Looks, set the Audio Route for a layer to 7+8. It will now play out of the physical channels 1-2 on that port.

3. Operator Hardware Monitor

You can now have a dedicated “Headphones” or “Monitor” jack on the server that you control from the UI.

Configuration

1. Go to Device View -> Caspar host setup (the server icon).
2. Under the Audio section:
   • Check Enable Monitor Channel.
   • Select the Monitor device (e.g., your motherboard’s line-out).
   • Save and Apply.

Usage

1. In the Top Bar, click the Headphones icon.
2. Under Server Hardware Monitor, select the source:
   • PGM: Listen to the main program output.
   • PRV: Listen to the preview bus.
   • Multiview: Listen to the multiview audio.

4. Troubleshooting

• No audio? Ensure the casparcg user has permission to use the audio hardware. See the Sudo and Audio Setup guide.
• PortAudio missing? Ensure your CasparCG build supports PortAudio and the custom_live profile is selected in HighAsCG settings.
