-Subject: [PATCH 084/114] Add a parameter to turn off SPDIF output if no audio
- is playing
-
-This patch adds the paramater auto_shutdown_output to the kernel module.
-Default behaviour of the module is the same, but when auto_shutdown_output
-is set to 1, the SPDIF oputput will shutdown if no stream is playing.
