Hey everyone, I just did a software update and since then I have not been getting any sound output from my MBP. When I increase/decrease the volume, the fade away window volume windows shows up and responds, but I don't hear any sound including the beeping sound that happens every time you change the volume. I havent changed any settings, just did a software update. Any ideas what might be wrong? I tired restarting my MBP, but no luck.
