Hi, Is there a recognized method for calibrating a sound card? e.g.
For Playback, one sends a sample .wav PCM file to the sound card, then measure the analog output from the line-out. If the sound card itself provides 0dB of Gain, what should be the measured figure? Can this be done with a simple AC volt meter? There seems to be some debate, with regards to ALSA, as to whether the line-out is at the correct level if one sets all the ALSA mixer controls to 0dB.
