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.

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.

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.

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.

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?

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.

Thx.

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.

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

pedromatiello · #13 15th June 2007, 08:12 PM

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 · #14 15th June 2007, 08:26 PM

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?

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.
