The reason you see the options for "caller ID" and "off hook" is that 
the Intel HDA chipset also includes a modem. My laptop uses Intel HDA, 
and I'm used to the modem part showing up as if it were an audio device.

The audio works on my laptop except for an inability to record from the 
mic input. Last I heard, ALSA was blaming the kernel, and kernel 
developers were blaming ALSA. Although I haven't tried it since my most 
recent kernel update.

$8 USB audio dongle? Where did you find such a thing? Tell me more.
