Hhhmmmm, but wouldn't a problem like this cause the metallic sound
everytime? In my case it works fine must of the time, but every now and
then I get the darn metallic noise. Also, I can fix it by running the
alsamixer and toggling on and off the capture setting of the ADC
channel.

I forgot to mention that when I am hearing the metallic sound, if I
increase the volume of the "line in" channel in the mixer, I hear the
audio from the TV tuner just fine (this is the bypass, from line-in
directly to the speakers). This confirms that the input signal is fine,
I think.

What I'll try next is to connect the audio output from the TV tuner card
to my sound card's microphone input, instead of the line-in input just
to see if there are any differences, although I doubt it.

Other suggestions?

Thanks,

Eloy.-
