I have a 2007 mac mini that is a backup computer. It works great, but just recently the sound started disappearing. By disappearing, I mean that the speaker icon greys out on the menu bar & I cannot play sounds through either the internal speaker or the sound out port. I've been able to fix this by opening the minit & resetting the PRAM via the button. Last night, this fix stopped working. Does this sound like it might be a dead PRAM battery to you guys? I can fix the battery, but if that is likely not the problem, I'd rather not tear the mini apart.
the only other way I know to see if the PRAM battery is working is to check the time/date, but that is normal. I am not sure if that is due to the fact that I have it auto-syncd to one of Apple's servers & as such, it auto-corrects before I can verify it.
If it's not the PRAM battery, does anyone have an idea what might be causing this? Thanks in advance for any advice you can offer.
