Audio cutting out

Audio cutting out

Hi everyone,

I just bought a new TV. It's a 55" LED Samsung TV, model number UN55D6420UFXZA. So the issue is this, I have a iMac 27" and I used to have a Sony 46" LCD and when I hooked my HDMI cable to my iMac with the Moshi Mini DP to HDMI Adapter with Audio Support it always worked like a charm. I use VLC Portable and it has been a pleasant experience until I got the new TV. I read in another post that some guy fixed his intermittent sound issue with his LG LED TV by playing with some sound option of course which I don't have.

The issue I am having is that the sound is cutting out like crazy. I do have a an optical cord hooked into my receiver to my TV which I did not have in the past and this may be causing the issue but I am unsure what to do here? I have a Yamaha 7.2 receiver that does not pass through the 3D that this TV has so that is why I have an optical cable connected to my receiver so I can have sound through my PS3. Anyone techy enough to try and help me with this gross issue?

Thanks

Adam

iMac, Mac OS X (10.6.8)

Hello Adam,

I am having the same problem with my Mini Display Port to HMDI Adapter; the sound keeps cutting out while we are watching a movie on the extended desktop, which is our Sony Bravia tv.

Just curious to see if you have solved your issue and if you have any advice!?

Thanks,

Amy

Hi Amy,

Well ironically when Lion came out there was a patch that fixed it. Do you have Lion on your Mac? I thought there was an audio patch for Snow Leopard as well but I'm not sure. What operating system do you have?

What brand is your mini display port? I bought this one:

Is the mini display port you have one that supports audio bypass?

I assume your TV is hooked up to a receiver? Have you ever had this problem before? Did it work before and not anymore? What is your setup? TV & Receiver and computer?

I use VLC Portable as my video player and it works like a charm. You do have to go into your settings icon and go to sound and change the output to HDMI and you also have to mirror your screens on the display icon while in your settings icon. I assume you know this but just in case you don't....

We just bought a new one from Future Shop - Rocket Fish.

It's connected directly to the tv through the HDMI cable.

I assume it supports audio bypass - some movies/shows work fine while others seem to "blank" out for a few seconds.

If this is the one:

It doesn't make mention of audio support but if you are saying it works that is odd?

Will these same shows/movies blank out while you are watching them on your computer directly?

Is there any audio settings in your TV setup that may be casuing this issue? Sometimes you need to change the audio in the TV to actually make it work as well. Like PCM or HDMI or whatever needs to be on while watching the show/movie. Do you know what setting your TV is set up on or are you not home to check?

Yup! That's the one!

The output is changed to the tv - it comes up SONY. The tv is used as the extended dekstop rather than it mirriored.

No, if I watch the movies/shows on the imac itself - the sound is perfect.

I will have to check to see if there is a setting in the tv - never thought of that!

I've been having the exact same problem for more than eight months. It's tied to 10.6.8.

iMac > Moshi HDMI Adapter > Pioneer Elite

The audio drops out every five or six seconds.

Apple is well-aware of the issue, but there have been no fixes.

I reverted my computer back to 10.6.7, and that fixes the problem.
