DolbyD 5.1 gives very weak sound

Posted by def456 on 04/19/07 04:39

It looks like most DVD movies these days come with DolbyD 5.1 as the only
kind of audio sound, but it doesn't work very well with my system. DolbyD 2
channels (48K) is OK, but not 5.1 channels. It's too weak. I have to turn up
the volume very high on my TV til I hear a background hum then the movie is
somewhat audible, but with very poor quality sound.

For example I can generally hear things OK when watching cable or satellite
TV with a level of 15 on my volume control, or with a DolbyD 2 channels DVD,
but I must turn the volume up to 30-40 or more to hear a DVD movie that has
DolbyD 5.1 sound.

I tried cleaning all of my audio cable contacts and it helped a little, but
not much.

I've looked around on the internet but couldn't find any cheap stereo/hi-fi
systems to use in place of my TV's audio system. They all want at least
$200, which is too expensive.

I have the red and white RCA cables for hi-fi (2 channel) sound. So a new
sound system must be able to accept those connectors. A lot of small
portable stereo players use a different kind of connector (just 1 plug,
divided somehow, like is used on computer speaker systems), but I need
something that accepts the RCA cables with the 2 plugins for the left/right
speakers.

I don't know or understand many of the details. I'm not an audiophile. I
just want decent sound, something like when I watch the news on cable or
satellite TV. It doesn't have to be great sound, but I have to be able to
hear it! Why does DolbyD 5.1 give such weak (low volume) sound?

Any suggestions?
