[ASUS S400CA,VT1802 , recording] Support of Headset Mic not implemented

[Aaron D. Campbell]

I opened a thread in the forums first. For reference: http://ubuntuforums.org/showthread.php?t=2230136&p=13052352

The basic issue is that I got a new Asus S400CA laptop. It has a combo jack for headphones/mic (like phones do now). With Windows 8, the headset worked fine (both input and output through the one jack). With Ubuntu 14.04 it works for output, but not for input.

It's been almost a year. I'm now on 15.04, same laptop, same issue. Here is my most current Alsa Info: http://www.alsa-project.org/db/?f=b2d205e49d5a715e4504ec50d5797e1d9659ff10

I'm not sure how to tag this bug as affecting "Vivid" instead of just "trusty" but it's definitely still a problem.

Thanks!

you need to find out the pin complex of the headset mic

I'm completely lost here, sorry. How can I figure this out, and if I do how does it help?

I've tried several headsets, but the one I use most often with everything else is just a set of Samsung earbuds much like these: http://www.samsung.com/us/mobile/cell-phones-accessories/EO-HS1303BEST1

you need to find out which unconnectecd pin complex is the headset mic

need to recomplie driver

patch_via.c

patch_vt1802

spec->parser_flags = HDA_PINCFG_HEADSET_MIC;

try three unconnected pin complex which pincap support IN one by one

I just pulled out that laptop, and this is definitely still an issue. I guess I let it lapse because I got a new laptop where this all works just fine.
