No Line-in Recording (3.5 HDD)

Hi,

i can't manage recording sound or videos with my Line-in. I tested it with Audacity and xawtv but still no sound.
I don't use any Soundserver (i tried OSS) and my onboard-Soundcard of the AK-39 Schuttle-Mainboard, TV-Card is an Hauppauge WinTv PCI BT878(Sound cames from the Receiver into Line-In)

Please help me

P.S. Recordings with Streamripper are ok, but i think Streamripper does not need any Line-in.
