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.

Note.PNGThe issue is fixed in Exigo-1.3.3.1.

More information in the release note for Exigo 1.3.3.1.
