alsa line-in will not boost audio

I have installed gentoo-2.6.12-r6, and now gentoo-2.6.13. Under both kernels, emerged alsa-driver does not make the line-in volume from my TV-card audible. Line-in input can be heard faintly through my speakers, but it will not boost it to a level anyone can hear, I ahve all the volume settings maxed-out and I still cannot hear anything. Is anyone else having this problem? I am using the emu10k1 driver for an audigy2.

ravalox,

There is no connection between the inputs on your sound cand and the outputs until you make one with some software.
All you can hear now is the 'crosstalk'.

Sorry, some more relevant information. I hear the 'crosstalk' when my TV-software is running. It unmutes the line-in and no matter what volume I have hte line-in set at I can only faintly hear the audio. At other times I hear nothing.

Which TV software do you use ?

I ahve tried tvtime and mythtv. Both look great, but they don't produce audio. I have checked the audio output of my TV card, and it's putting out audio the way it should, I get sound if I plug it into the microphone port or external speakers directly. But I need the line-in to work for purposes of recording. But at that point, it's an alsa problem. The audio is coming in just fine, I ahve a windows partition I can watch TV with and that uses this same hardware in the same configuration, its just a reboot away.

ravalox,

You can only get input from a single channel at a time, so you need to select 'line in' for recording in your mixer, instead of mic.

taht's good intel, I am tinkering with it now, I switched to the capture view in the alsamixer and while there is a 'line2' there does not appear to be a regular line available for me to set in capture. I tried setting it with the space bar but that doesn't seem to work like the man page for alsamixer says it should. Can you help a brother out, how do I set it to record line-in?
