Default Swap center/subwoofer on Asus Xonar H6 and OPAMPs

I am just setting up my 7.1 system for the first time and found that I wasn't getting any sound from my subwoofer until I ticked 'swap center/subwoofer output' in the Asus control panel. The bass redirection is on and set to 80 (same as subwoofer (Paradigm DSP-3200) and receiver).

My audio setup is: Asus Essence ST with H6 daughter card to Yamaha RX-V757 AV Receiver via analogue outputs. Note receiver doesn't have HDMI support.

I replaced the default OPAMPs with OPA2107 for centre and OPA2228 for subwoofer with default buffer. If I swap the channels in the driver software I am effectively switching the channels the OPAMPs are on?

Yes.

You can check this very easy.
Trace the OPA2228 to one of the RCA jacks.
That's the one you need to connect your subwoofer to.
Then whatever you do in software to get bass out of the woofer is correct.

Default H6 card

Where does one get a H6 daughter board ? I don't seem to find it listed anywhere on the Net. Isn't it called the Xonar H6 expansion board ?
I tried looking for it in Singapore and the US without success.
I already have the Asus Xonar Essence ST.

Any idea how much the H6 costs ?
Thanks.

I bought mine from Amazon. It is called the Xonar H6 expansion board. I paid about AU$120.
