I got an ASUS E200H now, and played a bit. With Simon's two patches and Pierre's two SST patches, and with two MCLK patches -- now I could hear and record. Not a bad start :)

However, the audio quality is bad: it plays almost only from the left channel, and at the end of playback it gradually to the right. Also a lot of crackling noise, especially at recording. Pierre, do you have any hint?
I'm looking at the clocking stuff, and CX codec driver looks a bit different from others...

Another issue is that a loud pop noise at the start of the playback. I'm not sure whether it's the same problem as the above, or a different issue.

And, a good news is: I hacked quickly the jack detection, and it seems working. The only problem with the jack detection is that PA doesn't mute the speaker when I boot with the headphone plugged. The ALSA jack element shows the correct value, so I suppose it rather a PA issue with UCM.
