no sound on hdmi

Hello all, looking for help.

I have a dell studio 1735 that was just upgraded from vista to windows 7 ultimate. I have an hdmi on the left side opposite the headphone jack. I used to connect my phillips lcd to the computer via the hdmi and watch tv shows. Now i cannot get the sound to work on my tv. The video works great and the sound on the computer works also but its not changing to the tv like it did before.

I have updated all the drivers audio, etc on intel and completed all windows updates. I have confirmed its not the hdmi cable or the tv via different hdmi connections and my antenna. can anyone help? Thank you....

Hello Walker,

Thanks for the info. I am not sure what graphics card I have. Can't remember how to get to it to see, do you know where I can view the type?

I went to the control panel, sound. Found (Speakers/headphones: IDT High Definition Audio CODEC)
and (Independent headphones: IDT High definition audio CODEC). I didn't see any HDMI out. Are one of these two what I am looking for? I did however go to device manager, sound and found 2 items: (IDT High definition audio CODEC) and (Intel High definition audio HDMI). I have been tring to update those two drivers thinking one is the problem but it says that they are up to date and functioning properly. restarted system 1 time then connected tv, still no sound. Restarted again with tv connected, still no sound. Any other ideas?

Thank you,

Fretworker

I'm in the exact same boat as you fretworker, but sorry I can't offer any help yet. I hope one of us or someone else can post a solution for this soon. Thanks

Do realize this thread is 8 months old - (Feb 2, 2010)

Can you post what your problem is, with your system specs?

Thanks

Yes, I do realize that this post is that old, but I just got a VIZIO TV myself and tried to hook it up via HDMI. So I have the exact same problem that fretworker has and the same specs (Dell Studio1735, Windows 7 Ultimate x32, updated all the drivers, etc.) I've googled for quite sometime and this defines my problem best.

My graphics card is the Intel GMA (not sure if its 4500)

So, once again, I don't see that HDMI option on my sound playback (even with disable devices displayed)

Any help is greatly appreciated.

My apologies, this is actually my first time posting on a tech forum. Once again, any help is greatly appreciated and if any more info is required, please let me know.

OK, two things....

First, you need to make sure you have an HDMI cable hooked up to a suitable HDMI system, such as a monitor or reciever. Looks like you've done that.

Than, go to Control Panel, Sound, Playback tab, and make sure the HDMI output is set to default. That will ensure your HDMI is the default sound output for the system.



Let me know.

I see, but that's the problem that I don't have the HDMI device shown as an output on my playback tab. Check out my screen shots:

So even though it doesn't show up on the playback devices(left), the device manager recognizes there is HDMI audio (right).

Thanks again for your reply and look foward to any more help.

I've also tried to update the Intel HDMI audio driver, but it's current.
