No sound on tv connecting laptop via hdmi
My problem is well known and if you look in a lot of forums and support sites you'll find this issue announced by others. I don't need answers like: "check your sound options in Windows and set HDMI sound option as default" or "right click and check "show disconected devices" or something like that in sounds properties of your LapTop"...
So I have the problem with getting audio to work via the HDMI cable connected my LapTop to my TV. LapTop HDMI --> TV HDMI. Video works excellently but I can't get audio to come out of the TV. It is interesting that I used to have the sound earlier some times and it was not so easy to achieve. It apiered after doing number of resets of the notebook or TV, or both for several times and changing playback devices under "Sound" and I can not say what was helpful. Now it is impossible no matter how hard I try. And I have tried a lot of things. Installing, reinstalling drivers, reseting to default my TV and computer settings, updating TV's latest firmware, restarting computer and TV with HDMI cable pluged in or not pluged in a lot of times, tried to reset computer and TV switching diferent Windows sound properties even uninstalled all audio under "Sound, video and game controllers" and uninstaled "NVIDIA Geforce 8400M GS" under "Display adapters" in the Device Manager and reinstaled back, tried to find answers on various forums and support sites. NOTHING... I have spent hudge amount of time on it. And as I can see I'am not alone with this problem. Thousands of people have the same or similar problem. But there is no concrete help. When looking at the driver version of NVIDIA graphic card it may seem it is out of date (10/3/2009), but when I downloaded the latest version (8/3/2011) I can not get even video on my TV. So I got back to the older version. I asked NVIDIA customer care for help. Above all that I mentioned they asked to check the BIOS options of the laptop for the changes that may be needed for the audio to be routed over HDMI on the laptop. I tried to check BIOS as they told. But there are nothing like audio options there in my laptop. So it is impossible to check anything for HDMI audio. After all these mostly computer works I started suspecting Philips TV. Can it be that somehow Philips TV's are guilty in these issues? Anybody have any more ideas, advices? I've lost all my hopes. :(
