Yes, only latest thinkpad models with this codec have this problem, old models don't need this quirk.On Mon, 07 Dec 2015 16:01:02 +0100, Hui Wang wrote:On 12/07/2015 10:47 PM, Takashi Iwai wrote:On Mon, 07 Dec 2015 15:38:05 +0100, Hui Wang wrote:On 12/07/2015 10:35 PM, Takashi Iwai wrote:On Mon, 07 Dec 2015 15:31:52 +0100, Hui Wang wrote: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: 0x10ec0293Hm, 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.

Judging from your description, I guess so.
I will add more information in the commit header and send the patch of V2. Thanks for reviewing.
