Hey there! I want VLC to mute in the background when a new program starts playing sound and unmouting VLC again if it has stopped. My idea was to use module-role-cork with trigger and cork_roles set to "music", but it doesn't work (both programs (VLC+Firefox) play sound at the same time or when run with "PULSE_PROP='media.role=music'" it starts repeating a piece like with a broken CD) Any idea how I can solve this issue would be very appreciated. Thank you in advance, Daniel
