Recently I've noticed the following two symptoms of defective audio:

1. The Left Hand speaker tends to buzz according to the strength of the audio signal. For instance a voice will tend to buzz more on stressed syllables.

2. After watching a substantially long video, perhaps 40 mins or more, on Youtube or VLC Player, for instance, a residual hum remains for some time even when no audio signal is present, and audio apps, in this case VLC Player, are closed.

It seems to me that the speaker has become physically damaged somehow. Perhaps a rogue signal passed through at some point and killed it off.

Anyone had experience of this or any suggestions of what to do? Possibilities of a repair? I am outside my Applecare protection.
 
You could try to get inside and replace the speaker, but something else could get broken in the process.

Easiest solution (may be cheapest in the long run as well):
Buy an EXTERNAL set of speakers and plug them in...

Yes I thought of that, you can pick them up quite cheap on ebay, dunno if you'd have to remove the logic board to do the replacement?

Seems to be an intermittent problem though, they've been alright ever since I posted this. Perhaps the personified speakers felt sufficiently threatened and intimidated by my publicly seeking assistance, saw the error of their ways and corrected themselves. All on a transcendental level of course. :p
