Simply put, I'm getting almost all the MBA set up. But now, to set the sound, I'm doing what all the threads suggest which is to put this:

options snd_hda_intel model=mbp3
into the /etc/modprobe.d/options file. But everytime I try to bring that file up, the terminal says 'no such command'. I'm typing this:

sudo /etc/modprobe.d/options
And I get a response that no such command exists. I have no idea why this is happening. I do appreciate any help on this.

Many Thanks, Frank B.
