ENA2xxx Shutdown Fix

An issue has been observed on Exigo-1.3.3.0 on ENA2200 and ENA2400 where audio channels goes in shutdown mode when playing audio with low frequencies.
To prevent this, a filter needs to be added to the channels to protect it from the very lowest frequencies.

1. Open SSH in the firewall
2. "PuTTY" (or another terminal emulator), and select:
