In Cablecast we give you many options to customize what you are presenting to your viewers. This is especially true with Cablecast CG. One of the areas we allow this is by giving you options for background audio to play while bulletins are showing on your channel.
In the software we give you 2 different options. First by uploading audio files and having them play with your bulletins. The other option is with a Line-in audio source. This is a great way to bring an outside audio source to play on your channel.
To do Line-in audio on a VIO server, it requires a few extra steps that we will go over here.
USB to Line-in Adapter
The motherboard that we use with the VIO line of servers does NOT have a line-in audio jack like the former Carousel Players did. This will require you to use a third party USB adapter.
We don't have a specific model or brand that we recommend, but we do want you to use a USB to Line-In adapter rather than a USB to Mic input. By using Line-In you are going to get better quality audio that will play much better on your Cablecast CG Channel. The only requirement is that is Windows 10 supported.
Once you have the USB adapter, plug it into a USB on your VIO Video server. This will be the server that is playing back video content and your Cablecast CG Channel. Do not plug it into your VOD or Live Streaming server and this will not work.
Once plugged in run any Windows drivers if needed and your USB Audio device will be ready to use and configure.
Configuration to Use USB Device
To configure your server to use the newly installed USB Audio adapter you will need to log in to the Windows desktop of the VIO Video Server. On the desktop there will be an icon for VideoServer Config Tool. Double Click on that to open it.
It will open a window asking if you want to allow this app to make changes to your device. Click on the yes button.
This will open the Video Server Configuration Manager tool. This tool allows you to setup and configure many different aspects of your VIO video server such at I/O configuration and Resolution. But we are going to focus just on the background audio so click on the Audio tab to go to those settings.
In the Audio tab, you will be able to choose from the dropdown menu which audio source you would like to use. You will want to select the newly installed USB Audio adapter from this list. (Note that your adapter might be named many different things. Just make sure not to select one of the Line In Blackmagic DeckLink Duo 2 options as they will not work.)
Once you select your device you will also have the ability to adjust the audio level.
When finished click Apply to save these settings.
Selecting Line-in Audio in Cablecast CG Settings
Now that we have the USB Audio adapter installed and configured, we can now set Cablecast CG to use that audio source.
From the main menu of Cablecast click on the Settings icon in the lefthand menu bar, then choose Cablecast CG settings.
Then choose the Channels menu option.
Then click on the pencil edit icon on the specific channel you want to set the background audio on.
In the edit channel screen you will then want to select the Background Audio tab. Once there click on Line In as your background audio source, and then be sure to click on save.
Now you are able to play Line-in audio with your new VIO server and Cablecast CG.
