HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

As the subject states the microphone isn't working anymore , I don't understand why or what caused this, today I just installed totem, however this last days have false-positives, stopped for sometime than again worked after some reboots, sometimes after closing vlc, but currently don't want to work.

- no pulseaudio installed , only alsa
- microphone worked just fine

arecord -d 5 test-mic.wav
aplay test-mic.wav
doesn't give me anything (nothing recorded)


aplay -l
$ aplay -l

Internal MIC I think is working, when it's enabled I just hear allot of noise when recording.

Please help , this is really crazy, I need the microphone to work for voip calls.

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

I read that for some worked "I had to change the mixer control "Digital Input Source" to "Digital Mic 1"" how can I do this?

Here is my /var/lib/alsa/asound.state
http://pastie.org/3127982

OTHER UPDATE

when I open gnome-alsamixer it shows Intel Cougar Point HDMI instead of IDT 92HD81B1X5

what's happening?

https://rapidshare.com/files/1147881049/test-mic.wav
is the wav file I hear during the recording - please hear with your speaker set to max

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

I seem to have the same problem. On my system I don't get the internal microphone. On the headset, I hear a feedback from the microphone to the headset speaker,  so the headset should not be an issue. I tried as root, to check for a permission problem. I blocked the hdmi in the kernel, to avoid an overlap in devices. I downgraded alsa. No success. r0b0t, have you fixed your issue?

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

Hey guys.. I have had the same problem. I know my microphone isn't broken since I can tap it really hard and I see a very tiny bit of feedback. However, I can't get any audio in Skype and no luck on what could be causing it.

I've checked the volume levels several times and all seems fine. There are a few things I am not sure about though, such as pulseaudio being default in /etc/asound.conf:

# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

# vim:set ft=alsaconf:

Here is the output for $ aplay -l :

$ aplay -l

I believe there is a strong possibility I need to set my microphone to Digital? I am no expert at this by any means.

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

I didn't change anything, was fixed by itself, no idea, I tried everything, but than just suddenly became to work again smoothly.
I had some old backup configuration files, maybe something in there,
have no clue hmm

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

is there anything different going on with alsamixer? What is the default device... etc

With my alsamixer configuration I have my Card and Chip listed as PulseAudio.. I wonder if I should disable pulseaudio and use something else? I guess maybe I need PulseAudio for many applications though. When I hit F6 and I select another sound card I see that "0" is listed as HDA Intel and the "-" default is PulseAudio. I am not sure what I should do exactly... does anyone have a recommendation?

I have the exact same problem, with the same hardware as rg_arc. Anyone please?

I still haven't found a fix to this... its really elusive to be honest.

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

Well it seems that I resolved the problem by adding: options snd-hda-intel model=auto
to /etc/modprobe.d/modprobe.conf.

And manually selecting the capture device on my application.

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

I've tried that and it doesn't work. Something is going on with Pulseaudio... its almost like I must completely remove Pulseaudio for Skype to work properly.

Hmm strange. By the way, I don't have PulseAudio installed.

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

I tried the method at the bottom of this page: https://wiki.archlinux.org/index.php/Sk … 82.0.2B.29

This seemed to do it for me:

Turn PulseAudio autospawn off, normally: $ echo "autospawn = no" > ~/.pulse/client.conf
Kill PulseAudio: $ killall pulseaudio
Shut down and restart Skype

Pulseaudio integration into Gnome 3 has caused so many headaches, however, pulseaudio is essential for several programs to work properly. I am confused about what to do now to be honest. In the notification area the volume icon isn't visible anymore, so the only way to turn the volume up and down is to use the terminal "alsamixer".

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

i have the same problem, mic not working on hp 4250 laptop,  trying to get to work for skype.

Codec: Intel IbexPeak HDMI

all volumes are up on alsamixer, nothing muted except spdif

rmmod snd-hda-intel -f && modprobe snd-hda-intel model=auto

  is coming in real handy.  each time i run it, i get a notification

Switching to the audio playback device HDA Intel MID
which just became available and has higher preference.

not sure if that message is worth anything, and theres a revert button there, tried that too. 

i tried other models as well, http://alsa.opensrc.org/Hda and no model as well.  i have 2 jacks, one is headphone, one is external mic.

  i also have an external mic hooked up and tried that, as well as my internal without the external hooked up.

using

arecord -d 5 test-mic.wav
aplay test-mic.wav

no sound is coming back.

oh yeah, a note on pulseaudio, i am not seeing that at all when i press f6 in alsamixer i get

-default
0 HDA Intel MID
enter device name...

oops, sorry for necromancing, should i make a new post and cross link this one?  the issue is near exact as OP

Re: HDA Intel PCH Microphone STAC92xx / Codec: IDT 92HD81B1X5 not working

well i got it fixed, it almost seems as if reinstalling gstreamer plugins and running this after did the trick

 rmmod snd-hda-intel -f && modprobe snd-hda-intel model=auto

  but i have to say plugging in a pair of headphones seemed to fix it actually, because it didnt actually work after i reinstalled th e gstreamer plugins,  and i had already ran that command several times, but somehow connecting the headphones kicked the audio system in gear, then iw as able to record and hear the playbacks at that point, then unplugging the headphones it was still working, then i tested it in skype and viola, it worked.
