Re: [mythtv-users] Integrated Sound vs. Sound Card, suggestions ??





If you use an optical TOS-Link cable from the SPDIF (IEC982) output on an 
audio card that supports it, and into your home theatre amp (most of them 
have a couple of SPDIF connections), *and* you can get your sound card to 
output through the SPDIF connection properly, then you can get good audio 
with no chance of a ground loop!  My motherboard has an SPDIF plate that 
goes into a PCI slot hole in the case, you can select to send your audio 
out through this instead of through the normal audio jacks using amixer or 
alsamixer or gui equivalents.

The audio stays in the digital domain, and you don't have to worry about 
the cheap and nasty audio amplifiers they put onto motherboards or cheap 
audio cards, or the poor power filtering in the computer, or the crosstalk 
from GHz radio signals flying around in the computer case.

I am about to set this up, once I have the LIRC remote control done, and I 
find a decent price for a TOSLINK optical cable ($20 for 1.5m of fishing 
line and some plastic connectors just shouts RIPOFF to me).


Luck!
