That's what I'm imagining from the description, too. Sounds like all power's off to the computer... so I'm imagining that... The card doesn't need "power" to work? Apparently no. This is the first time I've ever thought about that aspect. That's a constant checkpoint for things like those CHEAP $5 external hard drive adapters that have no enclosures, but it's never been a factor for PCI'ish/plugs into the motherboard type hardware. Is there some kind of direct wiring going on between the linein and lineout points? Yeah, I know, never mind on that one. There has to be something like that for it to work even when the power switch is on. Something goes in and can only go back out if there is an unbroken line of connectivity somehow within the product. :) Those thoughts are coming from sitting here reading Long Wind's description while knowing that my speakers power on and off separate from the computer. Wish I had some way to (kicks 'n' giggles) test the same to see if mine duplicates the result. Afterthought: This is a stretch of the imagination, YES, but........ Is there any way it could be seen as an exploitable vulnerability where it's possible to interact within the computer even when it's turned off completely? Absolute worse, hopefully totally impossible scenario would be that the boogeyman burglar busts into your office one night, plants some bad mojo on that PCI card, you boot up your computer the next morning, and off that bad mojo goes running throughout the rest of the internal workings... Yes, I do understand that the card would have to be capable of certain [tasks]. If that card's not capable, maybe others are? > input/output might be shortened on the board - why would you look at BIOS? Hail Mary pass...? Apparently because it's that annoying a (dis)feature? :) Cindy :) -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * runs with duct tape *

you hear sound even when you turn off and unplug your computer?
input/output might be shortened on the board - why would you look at BIOS?

I would expect personal computer sound card line-in and microphone inputs to use the same design analog-to-digital converter. So, the sampling rates and bit depths should be the same. But, microphone inputs are usually monaural. So, if you use a stereo patch cable from your television to your computer, you will only hear the left channel. And, microphone inputs usually have more analog gain. So, you will need to turn the television volume down and/or reduce the microphone gain in your mixer application. Either can reduce the signal quality. Failure to do so will result in clipping. You will get the best recording if you connect the television line-out to the computer line-in and match the signal levels. David

He does not know what brand his PC is and no info on the card - it is hard to say where and how it should be plugged in. regards

Thank David for your advice!
i think tv audio is stereo, connecting to mic instead of linein may result in poor quality
but i'm not professional artist, i can't tell difference most time
but for really good tv program, i will use linein

Just as loud as when the PC is running with the mixers turned up, turned down, muted? Or just loud enough to be a distraction if you're, say, dozing/sleeping in the same room? > i have to turn off speaker, this isn't convenient You say "turn off" rather than "disconnect". Is that because the speakers are being run from an amplifier that's independent of the sound card? > i mute all in mixer before shutting down stretch, it doesn't help > is there any solution? Thanks! Dunno. But it helps to have the problem explained. We can't do house calls! Cheers, David.
