PC to Analog 5.1 Reciever?

I have my SB Live 5.1 connected to an old 5.1 reciever without any digital inputs. However I am only getting 5.0 because the shared center/spdif/sub jack requires a 4-pole to 3 RCA adapter, which I have been unable to find.

Bacially I am trying to decide whether to buy a digital reciever or just a new sound card.

Questions

1) Anyone know of where I can find the cable needed to use the subwoofer channel on a SB Live 5.1? Anyone know where I can get the parts to build such a cable?

2) Should I invest in a new sound card that provides hassle free 6 channel analog output, or should I spend $300 for a decent digital reciever.

3) If a new sound card is waranted what would be the best one to get for use with a home theater system? I don't want to spend an arm and a leg, but I don't want to be dissapointed with the sound either.

Thanks


PS these are the same cables needed to connect the audigy's to AV equipment and are refered to in the manual as
"3.50 mm (surround)-to-RCA cable (available separately)"

Some of the jacks on the SB cards are two channel (3.5mm 3 connections)and some are thee channel (3.5mm 4 connections).

If you check you manual you will see that your audigy does in fact have a 4-pole socket with three channels, center sub and digital.

You can put a regular 3 pole jack ints a 4 pole socket, but then you only have access to the first two channels.

The digital out is on one of the first two channels so you should be able to use a 3.5mm to 2 RCA adapter and plug it into the coax digital input on any digital reciever.

Unfortuanely my reciever doesn't have digital in.

Maybe I will just mod my soundcard with an additional mono 3.5mm jack connected to the 3rd channel.
