For example, if you want to record a sound from an audio CD analog
output, try the following commands.  In this procedure we choose
ports/audio/wavplay as a recording and playback software.

$ mixer =rec cd			# Select CD as an input source.
$ cdcontrol play		# Start playback of the audio CD.
$ wavrec -S -s 44100 -b 16 -t 10 test.wav
				# Record a sound (from the CD drive).
				# Duration: 10 secs.
$ cdcontrol stop		# Stop the CD.
$ wavplay test.wav		# Play the test WAV file.

Of course you have already to connect the analog audio cable from the
CD/DVD drive to the audio CD input pinhead.

OK.  These settings may be good.
