Hi,

i've been to the local lenovo store and we tested this problem with various configurations.

What i can say is: This problem is HUGE!

Alright one thing at a time. We could repreduce the sound cracks/plopping with my config at the shop.

Than we tried:

- my W530 with a new 2011 docking -> sound cracking

- my W530 with a 2012 docking -> sound cracking

- a another W530 demo unit with a 2012 docking -> sound cracking

- a L430 unit with a 2012 docking -> sound cracking

All bios and drivers were up to date. The technican was standing there helpless and had no other ideas. He took my credetials and promised me to contact lenovo and report back when they come up with a solution.

We both guessed that this a problem is affecting the complete new 2012 thinkpad lineup because of the switch from the conexant to the realtek audio chipset.

What can be done to solve this issue? New driver or firmware (the newest driver from the realtek site has the same problem apart from this the dolby enhancement won't work too) Or do i need a new board with a new hardware revision that is fixed?

I am very stressed out because a can't really use sound on my docking :(

I made a quick video showing the issue in action: http://youtu.be/rj-OgAop1aY You see every time i start this windows alert sound it pops and than a few seconds later. Very annoying!

Thank you for your help

Regards
