Microphone not working on F7

[ski@efn.org]

microphone has stopped working after upgrade from FC6 to F7
audio working fine though.

Audio Card information as follows
"Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1"

thx

[chans_fdf]

same problem here :(

can't here microphone input and can't record from it.
audio output for other sources(CD's, MP3's, videos) is fine, however.

everything was OK in FC6.

Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02)

i've tried setting alsamixer playbck AND capture parameters many times without success.

Can I throw in a me too. I am using Gigabyte MB and using the on board sound card. When i first install it, everything was working, even though i found the sound a little soft. But Mic was working. After yum update today, and not choosing the kernel as kmod-nvidia has not been out yet. Mic stopped working.. and even worse when i run yumex to install the new kernel, it does not show up as available anymore.

I had exactly this problem and solved it a few minutes ago. It had been bugging me for quite a few days. I solved mine by some tweaking using gnome-volume control.

1. In the Playback tab, increase the volume level for the CAPTURE feedback.
2. In the Recording tab, increase the volume level for the Microphone.
3. In the Option tab, select Mic as the Analog Source.

If you cannot see these settings in the application, you must first edit the application's preferences to make them available. I hope it works for you as well.

[ski@efn.org]

it worked for me. gnome-volume-control can be launched from a x-term or you can get to it from System -> Preferences -> Personal -> volume control.

Thx.

[chans_fdf]

gnome-volume-control doesn't have 'capture feedback' or 'analog source' on my system - even
if everything in preferences selected. this is likely dependent on the audio device. gnome-volume-control
is just a GUI front-end to alsamixer. so the parameters in gnome-volume-control are what i see
with alsamixer, which i've been fiddling with for a long time now.

i believe my problem has to do with Alsa and the sound device i have. if someone has the
same combination, i would sure like to know how they are doing.

I also installed the ALSA Wrapping for OSS may be this helped me. I am not sure about it though.

Thx.

[suomaf]

I am such a noob.. After hours of googling, searching thru this and many other forums, looking up alsa, alsa mixer, alsa setting.. reinstalling alsa. The wife this morning looked at it in passing and said ummm shouldn't the orange thingy be in the orange hole? I HAD PLUGGED MY @#@#$#$ MIC IN THE WRONG @#$@#%# HOLE!

I have now offically lost my right to complain when the staff tells me my printer does not print and the printer is not plugged in.

Anyways MY WIFE fixed my problem.. and I have the computing degree.

[chans_fdf]

man, i wish that was my problem. but it's not :( cuz i verified that everything works fine in Windows.
we all lose a little common sense after all that higher learning :)

i installed alsa-oss-*, but didn't help. how do i use that subsystem?

[pedromatiello]

This is what works for me:

Open a terminal and run alsamixer.

Then press TAB, go to Mic and select it by pressing the space bar.

Quit with ESC.

each program is different. For e.g. in gnome-volume-control, click on File and change device select the Analog OSS Mixer.

In Skype, I have to get to the Sound Device through Options menu ans select the OSS device.

hope this helps.

yes, i've had this set for all this time. also have the Capture volume up high. still no good.

[pedromatiello]

Odd. Probably you already did this, but I don't have any other ideas. So, just to be sure:

Check if capture is not muted.

Also, type arecord at the command line and see if it's really not working (say something at the mic and see if a lot of random stuff appears). Maybe it's some app misconfiguration.

[chans_fdf]

yes, capture is un-muted.

for testing, i've been using arecord. i would record to a file. when i playback the audio file, it's
just quiet static. in FC6, when things were working, the audio file contained my voice recording.

is there some other way to use arecord to better diagnose this?

[nariknahom]

I have similar problem here. Has anyone managed to get it working?

[chans_fdf]

since my last post, i haven't worked on this much, so i still can't record the microphone.


nariknahom,

what audio device do you have?

[stanmc]

yes, capture is un-muted.

is there some other way to use arecord to better diagnose this?In order to make my microphone work under Alsa with my onboard audio device I opened the Volume Control and clicked on edit and opened preferences. I then selected Microphone Capture, MicBoost (+20dB) and Capture. After closing the preferences window I went to the Recording tab and raised the capture volume and made sure the mic wasn't muted on that screen. Finally I went to the switches tab and selected Microphone Capture and MicBoost(+20dB). That made the mic in Skype work. I haven't tried the mic with anything else.

The bad news is that some of these switches get reset somehow. I have to check them everytime i want to use Skype. I hope this might be of some help.

[chans_fdf]

yes, i've done this. just now did it again to double check, and things are set properly. and still no good.

[nariknahom]

i dont find the micboost option anywhere

[stanmc]

i dont find the micboost option anywhere
Are you using Gnome or KDE? Also, are you using Alsa? Did you try to enable it using Open Volume Control by right clicking the speaker symbol and then under Edit selecting Preferences and selecting Mic Boost (+20 dB)?

[nariknahom]

I am using Gnome, Alsa and the lspci output shows
00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)

But there is no mic-boost in edit->preferences.

[nariknahom]

what are the alsa and related configuration files for audio devices?
if someone has nVidia MCP51 audio device and the microphone is working in fedora, please mail the configuration file outputs.

the alsa config files i know are /etc/asound.* and /etc/alsa/*. i haven't tried changing any of
them by hand, though.

[nariknahom]

I finally got it working by playing with Sytem->Preferences->Hardware->Sound. When i changed the capture device to Conexant Analog, things started working. Alsa mixer has Mater, PCM, Ext Mic, Int Mic selected in Playback. IEC958 and IntMic selected in Switches.

Hope some this is useful to someone have HP pavillion dv6000 laptop!!

[FEDoEx]

I have the same problem on my laptop and desktop.

[chans_fdf]

oh crap! i got it working now.. i'm so vaklempt.

solution is to set Channel Mode to 6 channels. all along, i had it set to 2 channels. found this fix
at...
http://simonatlinux.wordpress.com/2006/03/25/no-microphone-on-a-p4p800-mainboard-with-on-board-sound-card-ich5-ac97/

what a relief.

[FEDoEx]

This solved the problem for my old desktop.

http://fedorasolved.org/Members/crash/audio-capture-in-skype-and-other-devices/

I am using KDE so I had to install gnome-media first
yum install gnome-media
to get to gnome-volume-control

However I could not resolve the problem for my laptop
I think I have the same situation as chans_fdf.

[chans_fdf]

FEDoEx,

did you set the Channel Mode to 6 channels (or what ever is the max for your device)?
instead of testing with Skype, try using arecord and aplay.

No I followed exactly the instructions from the link.
It is really old desktop and I don't think it has more than two channels as output..
I've just tested the recording successfully with arecord aplay and audacity. I could not record with KRec.

I also managed to get the microphone working on my laptop. It has stac92xx audio card.
Here is what system-config-soundcard says for my soundcard
Vendor Intel corporation
Model 82801G (ICH Family) High Definition Audio Controller
Module snd-hda-intel

In gnome-volume-control> Edit>Preference I checked ADCmux and that was it..
I do not have the options MicBoost (+20dB) and Capture.
The recording worked with arecord aplay and Audacity. Again KRec did not record anything.

[mwildam]

I did not have ADCmux. In my case it was the "in-gain".

BTW: Skype does automatically adjust that value when you make a call so you have to adjust it also while doing a skype call. Then it "reminds" that value for the next call.

When you then go to near to the microphone during call and you speak loud then skype again adjusts the in-gain and reduces it. But unfortunately when you then put the microphone wider away then it does not rise it again. :-(

So I think I have to check that value from time to time.

[mwildam]

P.S.: I used audacity for recording and enabled all options in volume-control. Then I muted everything one after the other while talking to the mic. Then suddenly audacity did not record anything any more and so I knew what was the right thing.
