Hello. I'm trying to get microphone working with Realtek ALC892 on-board audio.
I have ASUS M4A89GTD Pro/USB3 motherboard.
I've selected "snd_hda_intel" module with "snd_hda_codec_realtek" codec. Audio works great. Also I can hear myself, when I'm talking to microphone.
When turning on/off microphone in Kmix and alsamixer - I can hear sound difference, so it looks like they are able at least mute/unmute mic.

This command records nothing. No voice.

What to do? :roll:

I've hit this when I didn't tick the box for 'capture'

I don't know how else to explain it other than to screencap it and say "that one!" (screencap to follow)

Same symptoms, i could tap on the mic and hear it through my speakers, boss couldnt hear me on skype

I tick the box and voila, it works

it isn't all that straightforward configuring it just through alsamixer. In kmix i tick the box beneath 'capture', and all is well.

on this box yes, on another box (laptop) I didn't until I upgraded its bios, strangely enough

I did have to turn mic boost all the way down. Can you hear yourself speaking at all, or is it complete static?

Is the input source set correctly?

I don't have a ton of ideas, but that's what I can remember from having to fight this before.

Hi,

I've the same problem, it's capture, but it's only noise. It''s the same mainboard with the same audio chip.

I've tried a second mic........ maybe the mic was defect, but no, the same result.

Anyone the same problem?

Had awful cracking sound with even the latest kernel (3.1.2 as of this writing) drivers and my ALC892 device. Removed the drivers from the kernel and installed alsa-driver-9999 which apparently has some fixes for this device.

An update to my previous post. With the installation of gentoo-sources-3.2.0-r1 I no longer need the external modules from alsa-driver-9999, the crackling is gone and the sound is fine with the kernel modules.

I've retried it with kernel 3.7.xx without any luck.

Did you build the build-in modules in the kernel or did you build them as modules?

Built as modules. I'm currently using gentoo-sources-3.7.4.

I have:
  • SOUND [=y]
  • SND [=m]
  • SND_HRTIMER [=m]
  • SND_SEQ_HRTIMER_DEFAULT [=y]
  • SND_PCI [=y]
  • SND_HDA_INTEL [=m]
  • SND_HDA_PREALLOC_SIZE [=2048]
  • SND_HDA_CODEC_REALTEK [=y]

Basically only building the needed codec and not everything under HDA_INTEL - the other codecs are [=n]

Also using media-sound/alsa-headers-9999 and media-sound/alsa-tools-9999 plus motherboard is running the latest BIOS.

Maybe that info will help some. It is always possible that you have a hardware issue.

Note that at one point I needed to disable auto-mute for the Intel (Realtek) device in the alsa-mixer and although that doesn't seem to be the case currently I suggest you try that as well.
