I have worked with audio before, and can confirm internal audio codecs are very good for... trash them. If quality is of any concern for you, just try another adapter, i.e. an inexpensive Behringer UCA 202 USB audio interface. I've tried it with great results on OpenBSD, and you can buy it in

Hi, this you might already know, but good rule of thumb is to set the levels manually for each source (according to its dynamics), having peaks around -6dB to -10dB. If you have manual volume/gain control on your recording device/preamp, I'd set all levels in the computer to 80% of the scale and th
