Prevents SPDIF/HDMI digital audio playback devices from sleeping. Uses WASAPI, requires Windows 7+. To close the program, just mute the Sound Keeper in the Volume Mixer or simply kill the soundkeeper.exe process. If you don't like to run it manually after every system reboot, copy soundkeeper.exe to the startup subdirectory (to open it, press Win+R, enter "shell:startup", and press Enter).
- Sound Keeper is fully automatic and doesn't require any user interaction.
- Sound Keeper can keep sound on many sound outputs simultaneously (e.g. SPDIF and HDMI).
- Sound Keeper detects new sound outputs on the fly (e.g. when you connected a TV via HDMI).
- Default behavior can be changed by changing file name of the Sound Keeper executable.
- Primary audio output is used by default. Add "All" or "Digital" to executable file name to enable Sound Keeper on all or digital only outputs.
- Inaudible stream is used by default. Add "Zero" to executable file name to use stream of digital zeroes (like it was in v1.0.0).
