I recorded it (it is the same sound, the first is normal, the second is the distorted one):
normal:

distorted:

I suspect it has something to do with this:
When I rollbacked it back to 3.38.0.51, it looked like this problem was gone.Version 4.18.0.0 (Vista) / 3.38.0.52 (XP)
* (New) (Windows XP only) Enhancement of battery life during standby.
If somebody has the older version, either the 3.38.0.50 or 3.38.0.51, I would be glad if you could provide it for me. I wasn't been able to find one on the internet. Why Lenovo can't provide also the older versions of drivers, is unknown to me.
Thank you.
