hp laptop with IDT Audio, trying to connect to tv with hdmi

I have a HP laptop with IDT Audio on it, and I had a problem where my laptop was connected into my Vizio tv and I could get picture but no sound, I called vizio and they said with my tv i needed a Y-cable also. I bought a Y- cable and plugged into my headphone jack as told, but still I get is just picture no audio, and when I unplug the y cable from headphone jack the sound plays over my laptop? I called them again and they said it might be something with my IDT audio configuration... I have tried everything with no luck! Can anyone help with this problem? Thank you for any answers

 

right click your volume/speaker icon in your task bar, select playback devices then look for digital or hdmi speakers.

if there's none you may need to reinstall your sound drivers.
if your tv supports hdmi, I'm sure you don't need a Y cable for it. (unless I'm wrong).

 

I've already tried making ieverything the default device but it won't come through the tv. and in the tvs manual it says you need the y cable if you want sound... any idea where i can find the sound drivers?

 

What notebook model and exactly how are you connecting it to the TV?

Via HDMI?

It might not be the audio driver per se but that you might need a Nvidia High definition audio driver for HDMI.

List what it says in device manager under Sound video and game controllers. And also under display adapters.

Also, what software and what codec are you using? i.e what type of file are you trying to play? MKV, AVI, MP4, WMV? All that matters. You would need a codec pack to play some of those.

Let me know what's up and I'll see if I can hook you up.

 

Dumb question here, but I am going to ask just for "yuks and giggles" sake: does your notebook model even support audio through HDMI?

 

I had to install the HDMI drivers from an old catalyst to get HDMI in IDT.

 

well. depending on how IDT is feeling it sometimes doesn't default to hdmi audio in the IDT control panel.

So, while plugged in, go check the IDT control panel to see if the hdmi audio is active/you can make it the default. I know on my envy 14 you can't make any changes to the hdmi audio settings while there is no cable in the laptop.

Also like Bullit said:

you also may have to install old catalyst drivers (HP's amd drivers) and/or preview or hotfix drivers to get hdmi audio drivers because AMD doesn't bundle them into the basic catalyst updates anymore, but they DO seem to put hdmi drivers into the preview and hotfix drivers.
