Any way to prevent humm on PC-TV setup?

I just threw my shuttle on my TV in my room (realised that I only use it for my recorded tivo shows) But to get the sound to be... loud enough to hear I have to turn up the whole systems volume and even turn the tv's volume. This would be fine but when it is up that high there is an annoying humm that goes up with the volume.

Any way to purify the signal? I don't want to turn down the volume on the shuttle too much because when I go back to the regular cable it would be way too loud.

Better sound card and/or A/V equipment is pretty much the only option.

60Hz groundloop humm?
Does it go away if you unplug the cable tv cable from your TV?

Do you have it set up right? You shouldn't have to crank the volume up way high to get normal volume sound. Are your mixer outputs turned up?

Simple mini to RCA audio. I have eveything turned up (even the EQ for each level.)


No, it goes away when I unplug the mini-RCA cable from computer/vcr.

Youre adding too much gain
You cant just make volume appear out of nowhere so to say. Youre going to need to amplify the audio input

Sounds like a ground loop. Try cutting the ground wire from your mini to RCA plug.

Notice that you usually plug your speakers into your sound card? Speakers are amplified. You need to run that through an amp.

Use the digital out and then hook it up to a receiver.

Heh, this is for a 15" Daeweoo TV. I don't need a receiver for this set up.

I'm going to guess that when you do that you only get sound out of one speaker, as it doesn't contact the other part of the cable, which would put the primary load on one channel so your sound card isn't working as hard to drive the output. To repeat what the other people said, you need some kind of decent amplification.

Just my WAG
