I didn't have exactly that problem with the 159 kernel.  I was able to play sound but it was slowed down by about 1/3 to 
1/2.  I couldn't find a reason, and wasn't sure it was the kernel, but when I, like you, reverted to the 134 kernel 
sound began working just fine.  I don't use pulseaudio.

The 159 kernel seemed to work fine other than that.
