SL510 - No audio to television when connected via HDMI

[KMarshall]

Hey there. I currently have a problem connecting my SL510 to my LG32LE5900 television. I have full display, but all my audio comes out of my laptop speakers - not what I desire! 

It recognises the television as a Generic PnP Monitor in the Device Manager, but doesn't see any HDMI Audio in Sounds Playback Devices (It only shows Speakers Realtek High Definition Audio).

Any tips whatsoever? I have been searching the internet for a good hour now for different solutions and nothing has worked so far.

Many thanks.

hey KMarshall,

curious to know, have you tried on a different HDMI capable TV set ?

Just wanting to know if the same problem will occur on a different TV set

I clicked that I had this problem too, but wanted to expand on that. My SL510 worked perfectly connected to a Sony tv for over a year.

Then a few days ago, suddenly the sound was gone. I ran the troubleshooter, and the HDMI sound component failed the test (not surprisingly). Win7 asked if I wanted to make the speakers the default playback device and I clicked yes, as I wanted to watch something and figured I could change it back later.

Later on I shut the laptop down for several hours. On startup, I went to Control Panel->Sound to change the default back, but now, only the speakers show up as a choice. The HDMI option was there before; now it isn't.

How do I access it again? Or is that component just dead? What options do I have? Thanks so much for any advice.

Hi!
It seems that I have a similar problem. How did you solve your problem?
Some up-date drivers? Chipset, audio card or video card?
Thanks!
