Disable the aamix can fix this problem.
Which codec do these machines have?
Codec: Realtek ALC293 Address: 0 AFG Function Id: 0x1 (unsol 1) Vendor Id: 0x10ec0293
Hm, and only Thinkpads with this codec suffer? I mean, there are lots of TPs with ALC292. Please give more background.
Recently we enabled two thinkpad laptop models, both of them are based on the Intel skylake platform, and both of them used alc293 to be the analog audio codec. When the machine boot to the ubuntu desktop, there will be a notification sound when greeter dialogue shows up, on these two models, there is noise with the notification sound. By the way, we have 3 SKUs for each model, all of them have this problem.
See how more information you can give instead of a single line :)
After disable the analog audio loopback, the noise disappears.

My main question was rather whether this fix is specific to new models, and the old models likely don't need it. Judging from your description, I guess so.
Yes, only latest thinkpad models with this codec have this problem, old models don't need this quirk.
I will add more information in the commit header and send the patch of V2.
Thanks for reviewing.
