I then realized a bit too late that probably in your programming culture "echo test" refers to the whole technique you used to hook the kernel and debug the issue to produce the fix. If you call that technique "echo test" I'm sorry, I didn't know it was called that way. I just meant to briefly test to hear if there is noise even when the clock parameters are correctly hardcoded. My intent with that patch is to try to prove there's a firmware bug in action just like Takashi Iwai suggested. My apologies, Geraldo Nascimento
