I did some digging and found a post by Mark Hopkins, Program Manager, Lenovo Social Media:
"We do not have a policy that if you have a problem while updating your BIOS that you have voided your warranty.
It may be that some technician mis-understood or mispoke.
We rely on BIOS updates as a normal course of business to delivery updates and fixes to customers."

Hi Scottie... what model, spec and present BIOS version laptop do you have?
Do you see one full scale red spike every 65 sec in DPC Latency Checker?

I have a Lenovo Y560p and I'm having the sound stutter as well. It looks like it's worse than the OP's. I have disconnected my battery from the latop and I installed the BIOS that was in this thread. Most of the time I'm getting an average of <500 microsec latency but there are periods of times where the latency spikes to about a second. During this interval, my audio stutters and my video hangs. Any input suddenly appears after the hanging. I experienced this on both the Realtek and generic audio drivers.
I'm not sure what else to do here.

No errors popped up during the BIOS installation. The strange thing with these spikes is that it can happen at any time. I could be browsing the internet with nothing else open, I could be listening to music, or I could be doing something more demanding like gaming. When the spikes come, sometimes it freezes once or twice. Sometimes it gets as bad as the one in the screenshot. I had AIM open and I was playing a game when I took the screenshot.

im not quite sure of my observation on my laptop, but i notice that with the stepdown BIOS, if i were to plug the laptop on powersupply without battery, there will be a huge spike every now and then (around 30-40 sec timeframe). Else, it works fine with the battery while plugged in
