problem with tp.ms338.pb803 mainboard

[filigrana]

Greetings to the forum.
I have 4 NordMende ND32S3100H TVs that mount the BD_TP_MS338_PB803 board (as per service menu)...
After the switching on the DVB-T2 in Italy and the transition from the MPEG-2 video coding to the MPEG-4, a broadcaster (Mediaset) changed the coding of the Italian audio channel from HE-AAC to Dolby Digital+, while the English channel remained on HE-AAC...
The result was that all my 4 TVs have the Italian channel muted, only the second audio channel in English is heard...
My question is: does anyone know with certainty if this board supports the audio Dolby Digital+ coding or not?
I have the doubt that it does not support it, so I would like to avoid downloading tons of FW if the audio chip does not decode the Dolby Digital+...
Thank you.

On an Italian forum they told me with certainty that mainboard does not support Dolby Digital+ audio coding.
At this point, do you know if I can find a newer mainboard model that can be mounted on those TVs and that support the Dolby Digital+?
thank you.
