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.- ------------------------------------------------------- This SF.net email is sponsored by: The SF.net Donation Program.
