I am in Rotorua, and have a 2011 Samsung TV.  On some Freeview|HD channels, I receive regular audio drop-outs.  I have noticed it so far on:
1
2
U
3+1
Prime

I have never noticed it on TV3, and that got me wondering whether it was related to the HE-AAC audio they broadcast (TV3 being Dolby Digital).

I am interested to hear if you have encountered similar issues, and if so:
Where you are
What you use to receive Freeview|HD
What channels it occurs on for you

Likewise (particularly other Rotorua people) if you have never encountered any audio drop-outs, I would be keen to know what you use to receive Freeview|HD.  Some postings in the UK mention audio drop-outs being related to inbuilt receivers, but I am not too sure how relevant that is to us here in NZ.

Others on the Freeview Facebook page (and on here) seem to be experiencing the same thing.  I queried it on fb, and was told to send an email to freeview, so that they could determine what was up.  I did that, only to receive a generic reply, telling me it wasn't them, and to check my equipment and aerial...

Thanks,
Greg
