Fixed my pretty much unusable laptop which I recently upgraded to 7.0. 
Much better, thank you. I can't tell if the sound is better with snd_hda 
right now as per recommendation  of the list, go back to 6 I was told.  
Oh well, based on how well this worked, much better, I may go back to 7 
on my desktop. My fans kick in to high a lot less too now on my laptop 
:-D .
