Q: sound unknown

Hello

 

I got trouble for months with my mac book pro mid 2011

Sometimes when i reboot the laptop i have no sounds available.

I got this (printscreen)

The only way i found to solve the issue is to reboot and reboot again with CMD ALT P R

I m under Yosemite, but i have the issue since Mavericks (as far as i remember)

The only modification done on my mac is that i have upgraded the memory to 8go then to 16go with 1600Mhz DDR3 memory.

 

I have search here and on internet but see no one having the same issue. Anyone to help ???

MacBook Pro, OS X Yosemite (10.10.4)
