✨ Features

• Prevents SPDIF from going into standby

• Works with:

  • PulseAudio (removes module-suspend-on-idle)
  • PipeWire (disables suspend in pipewire.conf)
  • ALSA (creates .asoundrc for SPDIF keepalive)

• Interactive menu with progress indicators

• Automatically restarts PulseAudio / PipeWire

• Backup & restore of original configuration

• if spdif-fix didnt work for you, you can add the file "soundfixforautostart" to an folder make it executeable " chmod +x and at it to autostart. you need to install sox for your system for example " sudo apt install sox " or " sudo pacman -S sox " What it does: It generates and plays a sine wave tone (default ~440 Hz) in stereo, but with the gain reduced so much that it’s effectively silent.
