The right speaker on my macbook pro just stopped working the other day. Headphones still come through in stereo, but when played through the internal speakers, only the left one works. This is in every applications from iTunes to system sounds. Could this be something to fix from a software standpoint? I'm no longer under warranty. This is an Intel Macbook Pro running the latest version of Leopard.
I hate to break it to you, but it sounds like a hardware issue. Have you tried going into System Preferences yet? If not, go to System Prefs>Sound>Output tab and then check the speaker balance. If the slider is in the middle, then it definitely sounds like a hardware issue.
I'm going to guess you've had your MBP for a while now, which would mean that something inside like a speaker wire could have gotten knocked around enough to just fall off, or loosen a connecter just enough to make the speaker not work. That is, of course, if it is not System Prefs. Let me know how it goes.

This has also happened to my Macbook Pro - nothing would work, so i basically pressed the power button until it closed down and waited a few minutes and turned it back on. The problem ( touch wood) did not come back again yet. Good luck!
This is very subjective, but either the MacBook or MacBook Pro because the MacBook Air is more expensive than the Macbook because it is thinner, but does not outperform it.
Now between the MacBook and MacBook Pro there are so general guidelines:
-If price doesn't matter, the MacBook pro is the best Apple laptop because of its RAM and Aluminum body finish, also its Sandy Bridge processors and its new Thunderbult Port.
If price does matter, than there are some general deciding factors:
What do you do? If you work on your MacBook pro using PhotoShop and Movie Editors and a lot of software- the MacBook Pro is what you want. Also if you game, the MacBook pro is awesome.
Is it just for fun? If you want this laptop just for recreational use and not for games requiring heavy processing power for graphics, just get the MacBook.
There has been a known issue with the first key (any key) of a Macbook Pro, not responding when typed and Apple appears to have addressed this with this software update for the Macbook and Macbook Pro:
Run the Macbook Pro Software Update v1.1 and the Macbook, Macbook Pro Keyboard Firmware update v 1.0 per this link:
Connect external speakers, headphones, or optical digital audio equipment. The headphone / line output jack accommodates optical digital audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS). For analog headphone / line output a standard audio cable with 3.5mm metal plug should be used. For digital audio, a standard Toslink cable with a Toslink mini-plug adapter can be used. You can find the Digital to Analog converted:
