I meant July.
Because i had the problem right after the 13.7 update...
So if it's June at your pc than it's something else maybe....don't know.
For those who have it from last update i think this helps.it works for me so far,more than 24h already of normal work.
The latest driver didn't work...
*SOLUTION*
Hey everyone,i just had the same issue after the last critical update.
WHat i did is a recovery to 10.7.14 last critical update.when everything was good,and here it is after recovery everything is good and the sound working again :))
I also disabled those automatic updates for now...
