cannot hear sound after upgrading to dual HD SSD
I just finished upgrading my iMac 27" mid 2011 to Dual Hard Drive with a crucial SSD drive.
After booting the iMac up, I cannot seem to have any sound device anymore:
In preferences it says "the selected device has no output controls"
the Volume icon on the top-left corner is greyed out
at start-up I can hear the usual "Gong" sound, so the speakers are connected
I already tried both SMC and NVRAM reset without success
I am inclined toped it up again, but I would like to know what I should be looking for. Did I miss some connector? Which I should be check, more than others?
thanks to everyone for reading so far, and hope you can help me out
Is this a good question?
