Microphone does not longer work on Lenovo N581

Microphone does not longer work on Lenovo N581

[Manuel Reimer]

Hello,

I'm using Archlinux and so usually run always on the latest kernel.

But unfortunately somewhere with Kernel 3.9 my Intel sound got broken. 
Playback works, but no microphone is found.

So I keep downgrading to 3.8.8 for some months, now.

Can someone please help me with finding a solution for this? Is it 
really possible that the alsa driver "snd_had_intel" was broken between 
3.8 and 3.9 and noone found this bug, so far?

Thank you very much in advance

Greetings,

Manuel

seem N581 and U310 have same codec cx20590 and PCI SSID but different codec

First off, take alsa-info.sh output on 3.8.8 kernel where the internal
mic works.  Run the script with --no-upload option, and keep the
output.

Then test with the later kernel.  3.9 is way too old to debug, so test
with 3.11 or 3.12-rc.  If this still doesn't work, take alsa-info.sh
output again with that kernel, and attach both outputs for further
analysis.

Nice script. I did so and used "diff" to compare the two.

This way, I saw, that not only "Microphone" disappeared but "Capture" 
was added.

So I pushed "Capture" to maximum volume and unmuted the channel and... 
now my microphone works!

IMHO it is a bit confusing if "Microphone" is renamed to "Capture" ;)

And another thing, that seems to be misnamed, is the "Internal 
microphone boost" setting. If an external microphone is plugged in, then 
this setting also applies to this microphone. So maybe it would be 
better to name it "Microphone boost"?

Thank you for your help.

if your external mic and internal mic are 0x1b and 0x1f , the mic boost at
audio selector 0x17 is common to both mics as the driver did not use node
0x18 (another mux)
