(MUST) Specify audio source name ( The source names are got from getAudioSource.lua ) Note: In different products, digital audio source name may be different, like HDMI/SDI/... For software programming conformity, no matter which digital audio source (hdmi/sdi/...)we use 'DIGITAL' to represent; Similarily, analog audio source might be LINE/MIC/..., we using 'ANALOG' to represent. You can also set 'Source' to be 'AUTO', to let the device select audio source automatically. The auto selection ruler is: If the video source is HDMI/SDI/... which has embedded audio, just select the digital embedded audio; otherwise, it select analog source (Line-in generally). |
