You should invest some money in a decent audio card. Onboard sound is ok 
for playback of the system startsound and YouTube videos, but certainly 
not for recording. Something like the recommended Audiophile cards are 
ok. Make sure your Linux uses the ALSA sound system.

If you just need a simple way to record you can just use the "arecord" 
command which ships with the ALSA drivers. It can record in 32bit 
formats (if your audiocard supports this, why you should invest some 
money here) and can stop after a specified duration. It is currently 
limited to plain .wav files (thus 2GB max), but will split if reaching 
2GB, so no audio will be lost. When you edit your recordings later on 
you can merge your audio files again.
