Hi all. ALSA question here.
I want to split up and EQ my 2 headphone jacks separately.

My onboard (rear audio jack) is going to my 80w stereo system. It sounds great and needs NO EQ.
My headphone (front audio jack) goes to a subwoofer. That needs an EQ.

- It would be easiest if i could just open op some config file and limit the audio band to under say 200 hz or so.

I just want to limit what frequencies the front headphone jack broadcasts.
