lshw for machine experiencing the problem.

To reproduce (on Ubuntu 12.04 and intel HDA):
Just boot and log in.
Already startup sound can be heard crippled and all other applications playing sound show the same effect.

Problem not experienced in kernel 3.4, but 3.6-rc6 and rc7 have the problem.

could be this?


I suffered from the same and patched my kernel by reverting that change. Works fine now...

This bug should have been fixed in upcoming 3.7-rc1 and 3.6.2.
The fix commit is 99df18b31db389ec6abc8ad5415c14e7bb752b58.
