Default HDMI from PC to TV cuts out the audio

Rather than play the audio through my TV speakers, I connected my HP PC notebook to my Surround with a 3.5mm headphone jack cable which splits to 2 RCA connectors. Obviously, the audio quality was much better.

However when I connect the HDMI cable from TV to the PC, the video is fine and the audio immediately cuts out completely. I switched it with another HDMI cable and got the same result. Seems like the HDMI overides the other audio output and the PC can't sense this. This might be a question for a PC forum?
Can someone explain what is happening with the HDMI signal and if there is something in the audio set up for the PC that can fix this?

Thanks

try removing any other audio scource, then be sure it's set up in the control panel to do hdmi audio.

Are you getting any audio from your TV via the HDMI cable? It may be the audio is being redirected to the HDMI when it's plugged in since that's normally the way you'd feed video and audio to a device. If you do get audio at your TV, there may be auxiliary outputs on the TV that can be used to get audio to your surround system. Otherwise, there's probably a menu (as leevitalone suggested) in your computer that needs to be modified to direct the audio to the headphone jack. It may be that your PC is freeing itself from the audio decoding process when the HDMI is connected, since that would normally be done in the TV.

leevitalone and RBTO,

I do get sound with the HDMI cable only if I set the TV menu to play through the TV speakers. Set it to alternate audio and you get nothing. All my devices go to the surround for audio.

There are no compatible TV outputs to link to my surround. These newer TV's and other devices need more connections.

I'm sure the problem is with the headphone jack being disabled (audio probably defaults to the HDMI), when the HDMI cable is connected, as both of you have said. When I go into the control panel of the PC (HP G72B60US), it only lists the HP speakers. Can't find anything to enable the headphone jack.

Default Audio Problem Solved

I looked in control panel after viewing an HP forum and in right clicking, an HDMI Sony TV audio device came up. I was able to disable the audio to the TV.
Now it plays thru the headphone jack to my surround.

Thanks for your input!

Glad you found that. Don't forget where it is in case you ever want to go back to HDMI audio!
