maybe because the sound cards are also being used for karaoke.

Turn down the controller for the mic completely. It only controls how
much from the mic's signal goes through the analog mixer directly to
the speaker or line output, but has usually nothing to do with
capturing.

Then make sure that you have selected the mic as the input for
capturing, and use the input gain controller to adjust the recording
level. Depending on the sound card the mixer might have additional
controls like a switch for a 2nd microphone or a mic boost switch that
might need to be adjusted to get capturing from the mic working
properly.
