I finally got sound since I connected my GX620 to myh LTV.
The picture was great, but the sound is so low I can hardly hear it.
I am sending the tv converter back for another, but wondering if it is the computer.
Do I need to connect the one plug in point on the computer with a two prong RCA plug.
Now I am just using one plug to computer and one to tv.
I have a usb sound card that didn't do any better, and only produced sound on one stereo channel.
Head set was even lower audio.
Maybe I need to connect two channels.
Not really a fan of the onboard audio.
