Prevents SPDIF/HDMI digital playback devices from falling asleep. 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 digital sound outputs simultaneously (e.g. SPDIF and HDMI).
