I just picked up this card and cant figure out how to change the sample rate. I have the l/r outs going to a ppa. The signal is locked at 44. Is it possible to change the rate to 96 when using the l/r out to a amp? For playback I'm using foobar. The m-audio revo would automatically pick up...

Recently I assembled 2 cmoys and some xbox mods with a 30 watt radio shack iron. So far I went through 2 tips(the tips are rated at 30watt). They just seem to melt away. Is this normal? After soldering each joint I reclean the tip in a wet sponge and re-tin it. I dont think I'm doing anything...

Clicking channels tonight, I saw the new beastie boys video for their upcoming album "To The 5 Boroughs" on mtv. Anyway, can anyone identify the headphones Mike D is wearing or the ones the others have on. I've never seen cans that big. They look 20 years old. Looks like there will be a sacd...
