Hi,
This morning I rebooted my comp with the Mac OS X snow Leopard CD, in order to get rid of a password on the comp that was preventing me from downloading my wireless router. The problem is now I have no sound. I go to system pref--> Sound-->output and it says no output device. Did something happen to me internal speakers? if so, how do I get them back??
MacBook, Mac OS X (10.6.3), snow leopard
Hi Olga,
Have you done a PRAM reset, CMD+Option+p+r...

Have you ever had headphones plugged in to it? Sometimes the jack doesn't quite close when unpligging.
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.
Hi,
Thank you for your help.
1) I tried the PRAM rest-- and nothing changed on my computer.
2) I didn't have anything plugged it but I did try plugging in headphones now and removing them-- this did not help.
3) I dont see the input & output option when I open my Audio Midi setup --instead it says no output device found.
Any ideas??
Thanks again!
Hmmm, either sound IS really gone, or maybe some SW or extension isn't loading.
In System Profiler>Software>Extensions see if like this one is loaded...

Oh no! what do I do?
Are there any audio ones tere, different models may have different ones, not certain.
If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...
