[SOLVED] Sound output works, microphone doesn't, works in Ubuntu

SOLUTION: While I unmuted everything in ALSA, I missed this step from the ALSA wiki: "In order to record from a device, the device's "capture" switch must be set. To do so, run alsamixer, select your microphone and press space."

What sound card I have:

# From /proc/asound/card0/pcm0c/info
name: 92HD93BXX Analog
# From lshw
product: 7 Series/C210 Series Chipset Family High Definition Audio Controller
vendor: Intel Corporation
configuration: driver=snd_hda_intel latency=0

I've tried:

• Setting different models in /etc/modprobe.d/

• Blacklisting snd_intel8x0m

• Stopping PulseAudio and using ALSA directly

I've unmuted everything using alsamixer.

Sound output always worked regardless of what I tried, the mic never worked.

I'm not sure about the correct model and whether it must be specified in /etc/modprobe.d/. Looking at this list of models there is a STAC92HD83* but no STAC92HD93* (see output above). The laptop is a Dell Latitude E6530.

Interestingly, the mic is working fine in Ubuntu 13.04. Listing the snd-hda-intel parameters on both Ubuntu and Arch, it seems as if Ubuntu does not set a model.

Can anyone point me in the right direction to find the relevant settings that Ubuntu is using? Anything else I should do?
