I've recently setup watchdog using Intel hardware TCO that does automatically reboot the system it crashes (using Ubuntu LTS).

In watchdog.conf you can configure a timeout before reboot.

Defaults to 60secs.

Since my devices are playing audio in store which can be really problematic when there is a crash (sound gets stuck in a loop!). I'd like to know how low I could go?

I've used the default in_memory=true and realtime=true.
