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.
The issue is fixed in Exigo-1.3.3.1.
More information in the release note for Exigo 1.3.3.1.

Press enter.
At the end of the file add these lines:
[DAC_Left_48000] Biquad_A=7C7E7A8381867C7E7A7C723086EA76 Biquad_B=583A4A583A4A583A4AAE1B55C2E02C [DAC_Right_48000] Biquad_A=7C7E7A8381867C7E7A7C723086EA76 Biquad_B=583A4A583A4A583A4AAE1B55C2E02C
