This is the problematic audio (estype 135) and it is not being processed by '(E)AC3 audio parser functions'.

Mister Pablo R - See attachement documentation about (E)ac3 standards.
In this document, search for "Stream type" value - all are listed. If I see it well, "estype 135" is on page 259 (...)3.1 Stream Type
E-AC-3 bit streams shall be identified with a stream_type value of 0x87 when transmitted as PES
streams conforming to ATSC-published standards.(...)
But (E) Ac3 also uses other IDs so the file ""/src/parsers/parsers.c" need to be fix.

It should, but I'm not a programmer

Yes of course.
I do not understand how the current 'parsers' work so we have to wait.
But I see this is probably nothing difficult.

Try to add this code bellow https://github.com/tvheadend/tvheadend/blob/master/src/input/mpegts/dvb_psi_pmt.c#L363 :
case 0x87:
hts_stream_type = SCT_EAC3;
break;

Now it's OK.
Thanks for the quick help.

@ Jaroslav Kysela - Will you also add other "Stream type" values from the documentation of the (E) AC3 standard?
For example, (page 259): 0xBD (indicating private_stream_1)
