Sound isn't audible in the ESV for turn signals, bluetooth audio or the radio. After a 30 minutes of driving shut off the truck and turned it back on and it worked again. My brother also has a 2009 ESV and the same thing happens to him intermittently.
Any ideas?

Sounds like the amp never turned on. Turn signals, BT, Onstar all go through your radio and its speakers

Yup happens to me every once in a while, if you turn the truck off and wait the 10 minutes for all the power to turn off then turn it back on it will work fine. the dealer checked everything and couldnt duplicate the problem so there is no fix yet. i have an 08 EXT the back speakers work but nothing with the amp works, no fronts, turn signals or button beeps.

So just to make sure the truck definitely has to power cycle? It won't just turn on while you are driving?

No. I'm guessing there's a relay to the amp that's not getting switched on. If that's the case, it won't "just come one". You'll have to remove power to it, and then re-power it and that's by turning the truck off and back on.

Bagbklyn, would you consider going to the dealership for your audio concerns? If you send me an email with the last eight of your VIN, I would be happy to check my resources further for you!
