Hi,

I have no audio on TV (using hdmi) on Iranian English language Channel Press TV HD.

If I stream live signal to PC, using Videolan, I get it perfectly on PC.

ET8000 is up to date, and channels are just re-scanned.

Any Ideas ?

All other channels on this transponder are OK.

Multiple audio tracks?

No, just one.

Do you have the frequency, I'll test it then also here.

With what receiver have you tested this issue (and with with image version)?

Same Problem here with ET 4000 and OpenPLi 4.0

DVB-S2 12437 Horiz. 29900. 8PSK 2/3

ET 8000 Openpli 4. 2014-06-06

Audio track is AAC-HE

Hispan TV HD on this freqüency, has ACC-HE audio too, and can be heard perfectly.

Press TV HD use AAC extension:SBR

my reciver is VU+ Duo and OpenPli4 update 06.06-2014 and no sound to on Press TV HD

I don't know if they (IRIB) have changed audio codec, but this channel had audio correctly since a few days ago.

It seems that our boxes don't support HE-AACv2@L2 / HE-AAC@L2 / LC@L2 codec.

See also here: http://en.wikipedia....Coding#Versions

So, boxes need Drivers update ?

As far as I know Broadcom only supports LOAS and ADTS but not LATM.

If the current broadcom chips are able to decode it, then a driver update is necessary. Right. And then I guess the manufacture needs to buy a licence for it. I'm not very confident that that will happen soon or ever...

Audio is back on Press TV HD.

Yes, right. There was a change:

So now "HE-AACv2 / HE-AAC / LC" instead of "HE-AACv2@L2 / HE-AAC@L2 / LC@L2"

I've sent them an email several hours ago informing that nobody was able to hear it. I don't know if they've already read it, they haven't answered...
