Internal speaker issue - muffled

[MacHamster68]

its only for testing and it will work and wont harm the mini and wont harm the speaker , it is for testing and not a permanent thing

Uhh not true at all. Different speakers have different power ratings because they have different strength magnets. You apply a weak signal to a powerful magnet and the speaker won't work at all. You apply a powerful signal to a weak magnet and you blow the speaker.

It sounds to me like somehow your speaker got damaged/blown by running it at max volume. If it sounds ok at very low volume but muffled/distorted at higher volumes, then its not a connection issue.

I tried connecting another mac mini internal speaker today..and still just muffled noise!!! So frustrating. Any other ideas?

sorry if all connections are fine and the speaker is fine and all settings are correct, then it might be eventually normal output for the internal speaker but as you said it was working fine at one point i guess there is something wrong with the output so might eventually bad soldering if all connections are correctly fitted

but as it happens quiet often that the internal speaker plays up after upgrading ,that might be the reason why apple does not consider the mini as user upgradeable
you have to remember that its only a speaker designed for "notifications" sound mainly startup chime and some warning sounds

Just of note, but does the output when an external speaker is connected to the headphone jack sound normal?

yes... completely normal. That is why I do not know if it is a software issue? This may have happened after I went from 10.5 to 10.6.2. Not really sure though. Any other toughts?
