Re: Start pacat on boot (or after xbmc)
Hi again,
The bad news is that no one answered my e-mail, the good news is that
I managed to solve this myself.

This is now fixed by adding the following cron job (crontab -e)
@reboot sleep 10; /path/to/vinyl.sh
I think the issue was that pacat was started too soon (before
pulseaudio), and thus the sleep makes sure that the system is fully
operational.
If you do this yourself, you may find that 10 seconds is not enough,
since this was a pretty minimal system with a SSD.
A better approach would be to check 'ps' for the pulseaudio existence
in a loop with a sleep 1,
thus minimizing the time between full boot and starting pacat, while
still being sure it doesn't launch to soon (even on slow systems).
I'll have a go at that tomorrow.
Best regards,
Steven
