Hello Takashi,
On the Lenovo P520, there are two analog codecs, the codec#0 is alc662, and lineout, linein and mic-in are on the rear panel and are connected to codec#0, the codec#1 is alc235, it connects an internal speaker, front-panel headset jack (headphone+mic).
After booting up, only the lineout on codec#0 works, if i manually change value for some amixer controls (pulseaudio can't handle new controls like "Front-Panel"), the linein and mic-in on codec#0 also can work. But all ports on codec#1 can't work no matter how I change the value of the amixer controls.
And you mentioned UCM profile, where can i find it and use it?
the alsa-info.txt for this machine is at here：

Thanks,
Hui.

Hi Kailang,
We have a Lenovo P520, but the audio on this machine does not work, this machine has two codecs alc662 (codec#0) for rear-panel and alc235 (codec#1) for front-panel. Basically both the output and input can't work (only lineout on rear-panel works), it is because the pulseaudio can't set "Front-Panel ...".
And I found you sent a patch to support dual codecs on P520, and you mentioned UCM in the commit header. Where can I find that UCM, or how can I make other ports ( like speaker on codec#1, headset port on codec#1, line-in and mic-in on codec#0) work?

Lenovo P520/420 build with two codecs. ALC233 for front panel. ALC662 for rear panel. This patch will rename capture name for slove conflicts. And create a card longname for UCM profile.
