Bridge Sound from TV Tuner Card to onboard Sound Card?

Bridge Sound from TV Tuner Card to onboard Sound Card?

Post by Spar » Tue, 04 Mar 2008 01:02:45


My last PC had some connections on the motherboard to bridge the sound
from the TV tuner to the onboard sound card. My new PC (Dell Vostro
400) does not have those connections on the motherboard.

Can I splice a headphone jack connector onto the three-lead wire so
that I can then plug it into the "Line In" jack on the exterior of the
case? Is the signal the same? What is the wire->connector mapping?

Thanks!

My TV goes into "line in", just be sure you are using the "line out"
output from the TV. The other header that might work would be the one
from a CDROM drive.
One other "gotcha". Some TVs still have a connection to the neutral so
you can get some hum. Radio Shack (and others) have an isolation
transformer that will decouple this.
My 3 year old Daewoo TV would trip a GFCI when connected to a PC until
I hooked it up through the transformer.

Headphone out and line in are generally compatible, even if
strictly different signal clases. Typically you can use
a straight 3.5mm connector cable with headphone-type connectors on
both sides.
