The microphone is not working in Asus F555U in Ubuntu 14.04 and kernel 4.2.0-27-generic. By running the command
arecord -l I have found the following:
**** List of CAPTURE Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC256 Analog [ALC256 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0
I have searched and tried in vain to fix this issue.
Issue can be found here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1447909 and also here: http://ubuntuforums.org/showthread.php?t=2304274
Please help resolve it.
