Hi, I am not a kernel developer, but occasionally dig into it if something gets in my way. On Lenovo X200 Tablet none of the mixers showed Mic Boost adjustments, but HDA-Analyzer found them and adjusted properly. So I inserted the corresponding controls, and it worked. Then, during testing I found that the labels of External and Docking Mic are swapped, so I exchanged these too. Since I could not test it on other hardware, I put it all on lenovo-x200 branch. The patch applies to 3.1-rc2, I hope it is sufficiently recent. The Mic Switches don't have any effect on my unit (X200T without modem)
Could you try model=auto instead of patching? The recent auto-parser should work better.
Model=auto seems to give a very generic configuration, which indeed does include working Mic boost for Internal Mic. (Ext?) Mic Boost and gain are also present, but jack sensing does not work, so these cannot be tested.
The automatic mic-switch by jack-sensing works without model=auto, right? Then we need to fix it. Could you give alsa-info.sh output?
Also, the Dock Microphone is not detected, so I would conclude that for X200T "auto" does not work.
OK, it means that BIOS doesn't set up the pins for docking-station.
It would be surprising if Auto was better than dedicated model. (X200 and X200T accept same part numbers for audio card).
The auto-parser is nowadays much better than the model specific quirks. I'm going to reduce model quirks as much as possible now. So, basically, I won't add a model fix any more unless it's unavoidable. In your case, we'll need to fix pin configurations (like in patch_sigmatel.c or patch_realtek.c) and fix the auto-parser.
The kernel version that I used for this latest testing is 3.0-ARCH
It would be nice to get the mute switches to work as well.
Which mute switch do you mean exactly?
thanks,
Takashi
