I don't know if I have done something wrong but I can't get the audio in sync with the video on TV3.
The Video leads the audio by about 1/2 - 1 second

I have a Samsung 32" lcd tv with built in freeview receiver. 

I am receiving via uhf on the ngarara road transmitter in waikanae.

It is really noticable when the news is on, but no so much when programmes are pre recorded.

Signal level is 74% with BER of 0.

It does not seem to have any affect on any other channels???????

What series/model Samsung is it? There have been some known audio sync issues with Samsung TV's.

Are you using the audio outputs or is this through the built in speakers?

If you look around the forums... there are a number of people having such issues recently with TV3. The setups are ranging from HTPCs to your Freeview enabled TV so I'm beginning to suspect something has changed in the signal. I started getting the same thing a couple of weeks ago from my Media PC and initially assumed I had done something stupid or it didn't like something I had subsequently installed. Since then... I keep seeing people with the same issue. Who knows... but it seems suspicious.

I am only using the Television speakers.  All settings are default.  Do I contact Samsung and find out what is going on, or do I need to contact Kordia?

Someone made the mention a long time ago in the big ET thread that sometimes the audio is lagging by a huge amount. This was leading to the infamous audio dropouts as the units timed out before the audio did arrive.

I've heard a few people mention this just lately with different htpc/set top boxes too so it may be a broadcast issue.

What model Samsung do you actually have?

The reason I'm asking is that some earlier series 5 and series 6 TV's let you switch the audio format between HE-AAC and AC3. All newer TV's default to AAC and give you no option of selecting AC3 which means there is no way to get 5.1 sound out of the TV via the SPDIF connector.

When you view TV3 do you see HE-AAC appear onscreen?

From people I've spone to I'm unconvinced there are any issues at all with the broadcast signal. I believe it's an issue to do solely with the STB/HTPC/TV. Only a handful of people are reporting these issues.

Model is LA32B450 Samsung Series 4

It is showing AAC audio.  Under tools there is an option to select
AC3 but it will not let you.

Yes I've had no problems on my gear either, but just lately a few people have commented on it as dklong mentioned above. 

Do any of the freeview digital tuner built in TVs actually offer Dobly 5.1 out via digital coax/optical outputs from the TV itself?

I'm only aware of the Samsung's that don't. Certainly the Panasonic's and all the Sony's do and my understanding is the LG's do also.

The Samsung issue isn't quite so clear cut though - earlier models did and earlier series 6 firmware did. It just seems that every model out since then doesn't and trying to find an answer from Samsung as to why this changed is impossible.

Aye, I reported the same issue a wee while ago. The strange thing is TV3+1 seems fine (as do all other channels). I would almost go as far as to say that the audio syn issue is getting progressively worse over time.  I'm running a HTPC with MP 1.0.2. I'd be interested to see if anyone has any possible explanaitions/guesses.

I'd go as far as suggesting your problem is unrelated and sounds more like an issue with whatever AC3 codec you are using (assuming you are using AC3 for TV3) since it's not affecting other channels.

Do you get the same issue if you use AAC audio for TV3?

I only use AAC for TV3 unless I am watching an HD broadcast with an AC3 stream then I will manually switch audio streams. All AC3 audio is passed directly to my amp for decoding. The thing is, I have not changed my setup in months, and things *used* to be fine. I might check and see if there is a monogram aac codec update, but as all*other channels are fine, it would be surprising if this were the issue.

Do you encounter the issue with both AAC and AC3?

There is no delay when using the AC3 audio stream. An updated AAC codec makes no difference.

lchiu7: TV3+1 is AAC only isn't it? No DD here.


Correct.
