Hello, I'm Alessio, I'm italian and I'm newbye on this forum.

Let's show you my problem.

I have an HP Pavilion dv6-3102sl notebook with Windows 7 64 bit home edition.
if i connect my laptop to my hd tv via hdmi i have no sound... but the laptop's speakers sounds. IDT High defnition works.
In this case if i change output to Ati High definition Audio I can't play mp3 files, and it takes no control of applications sound.
Particularly the ATi high definition volume control never moves.
But if i connect my playstation 3 to the same television i can listen to it.
And if i connect my hp laptop to another hd tv i can listen to this too!
Why does my ATI High Definition Audio create this problem?

Sorry for my bad english.

Hello, Alessio, I'm not Italian but, I understand your English well. Certainly allot better than you would understand my Italian. :D 

The AMD High Definition Audio Device is your video cards Audio Device and only works in conjunction with some type of video for playing the video's sound only. This will not work for MP3's or any audio that isn't directly related to the Video you are watching. Sounds stupid I know but that is the way it is, this all has to do with (HDCP) High-bandwidth Digital Content Protection. :sol: 

In a case where you are connected to a TV as a monitor your desktop is your video.

I understand what you are saying, but I can play mp3s via hdmi with the same laptop... it's very strange.

Anyway, do you have any solutions for this problem?

Thank You.

Honestly, I've never heard of that before (mp3s via hdmi). Maybe it's something new? I really don't know, sorry.

Anybody else?

And then the sound from the MP3's comes out of the TV or the laptop?

out of the tv, if the ati high definition audio is selected

If you go to Control panel >sound>playback tab you can select your playback device.

If i understand you correctly with HDMI connected to your laptop one TV allowed you to play MP3's through your laptop speakers and one didn't.

That could have been because one TV had the laptops HDMI output selected as it's input and one didn't. :sol:

OK, well in that case I have to admit I just don't know. I hate that.

However you still could try selecting the output Via; Control panel >sound>playback tab, you can then select your playback device. :sol:

ok, you are very gentle.

So, with my LG hd TV and my hp laptop, I selected the ATI high definition audio as the default audio device.

The problem is that I have no sound through it... no bouncy green audio level...

nothing.

The ATI high definition audio as the default audio device is the one you want for HDMI. You don't have anything muted right? And your sound is turned up on both your laptop and TV right? :sol: 
August 13, 2012 9:32:16 AM

Are you playing a video through your laptop to your TV?

if I try to play a video, I can play it, but I have no sound through the ati hdmi device...

If I try to play an audio file, I can't play it.
August 13, 2012 9:42:24 AM

Ok Got you. Does this same video play OK on a differant tv? through HDMI?
August 13, 2012 9:46:17 AM

when I do the sound test for the ati hdmi audio output, I have an error:

the device is used by another application.

Yes, it does.

Go to Control panel >sound>playback tab and tell me what playback devices you have listed.

ATI HDMI Audio Output( ATI High Definition Audio Device)

I have a sharp TV hooked to my laptop via HDMI. When I look at my playback devices I have "Sharp HDMI" listed which is what I use.

The fact that your laptop works on another TV tells me that this is a not an issue with your laptop.

Some TV's will let you select an alternate audio source (usually the 3.5mm headphone plug) when using a computer through HDMI. Check your TV's settings to make sure you don't have an alternate audio source selected for that HDMI port. :sol:

Have you tried updating the ATI drivers?

Is HDMI audio enabled in the bios? (if there is a setting)

Theres no problems with any device in Device manager? Usually theres 2 entries in device manager for ati high definition... that need to be enabled/working.

Yes I have updated the ati drivers and there's not a setting in the bios to enable the hdmi audio.

But I have an unknown device in the device manager and I can't find his driver.

And I haven't 2 entries for the ati high definition, but only one.

ok the solution is to install realtek ati audio high defnition driver

Now it works

... now I must uninstall original AMD ATI driver?



SOLVED :)

Or you can just disable it in Device manager in case you need it for something else.

Anyway I'm glad you got it working! :sol:
