I am trying to set a profile persistently across reboots. Manually doing the following works:
$ pulseaudio --start $ pacmd set-card-profile 0 'output:iec958-stereo'
But, it is not persistent across reboots, so I edited ~/.config/pulse/defult.pa appending another line:
set-card-profile 0 'output:iec958-stereo'
Adding the line to the end of default.pa causes pulseaudio to refuse to start with the error 'Daemon session failed.'
How can I keep the profile setting persistent across reboots?
