It's unspecific in several other ways. > TV audio output What sort of output?

Enumerate the inputs and outputs, how they are labelled, and which ones you are using. > speaker is connected to output of sound card What, directly? Full-size passive speakers, or active ones with some sort of amplification built into them. > tv sound can be heard even when pc is shut down How loud? 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.
