I know this is a easy problem to fix normally, but I've had no success yet. I have a Sony Vaio FW with Windows Vista, and a Maxent TV. I've connected the laptop to the tv with an HDMI cable. The image is displayed on the tv with no problem but there is no sound whatsoever. I've gone to the control panel and changed the default sound device to HDMI Device, still no success. I went into "Configure" and pressed on "Test", and it says it failed.
I've also noticed that when I play a movie or anything at all with sound, the computer itself doesn't register the sound, because I click the sound icon in the bottom right corner, and normally there's a green bar that moves up and down according to the volume of the sound currently playing, but when it's set to HDMI there's nothing at all.
Any help would be appreciated.
