About SPDIF Keep Alive utility
SPDIF Keep Alive is a Windows .NET utility that keeps S/PDIF, HDMI, and DisplayPort audio connections active when no sound is playing. Some audio devices may stop or disconnect an output after silence; the utility is designed to prevent that idle behavior so the audio connection remains available when playback resumes. The application is a graphical utility for maintaining digital audio outputs rather than playing or processing sound itself. The supplied information does not explain how it keeps a connection active, which audio devices are supported, or whether all three connection types behave identically. Its role is addressing audio links that become inactive during silence.
