Microphone problem

Hi everybody. Mic does not work. Trying alsamixer, arecord, aplay and results negative. A have Dell notebook. Mic build-in. I put support to PC speaker in to the kernel. Alsa works fine, but without microphone. My notebook have special port for second microphone. May be system some how use this line instead of first microphone. Any clue?
Thanks a lot for help.

Re: Microphone problem

hi
I have dell notebook, sound is by sigmatel STAC9200, module snd-hda-intel. I had problems with mic, but eventually got it working by loading module with model=ref as option. This gave me more options in alsamixer. I also created .asoundrc like this

pcm.hda-intel {
   type hw
   card 0
}

ctl.hda-intel {
   type hw
   card 0
}

but don't know if this is important or not
anyway - it works.

Re: Microphone problem

I had the same problem. Try the solution in Wiki, though, its for Skype. Read section: "B. Making ALSA + dMix work for Skype"

Give what you have. To someone, it may be better than you dare to think.

Re: Microphone problem

Thanks a lot for all yours help but... First of all I  really do not understand what is go wrong. I have the Maestro sound card on my laptop and (may be) something which has the name chip Sigmatel STAC9721,23.I say 'may be', because, from one hand, I can't find any clue about this device on my laptop documentation from Dell site and, from other hand, I can see the name of that device  on left top corner of alsamixer screen. So I decide to build-in both drivers directly into the kernel.I was trying to use all of your's advices and unfortunately the result was negative. I am not test the Skype installation  recommendation from Wiki yet,  because after upgrading pacman,  I can't retrieve alsa-oss (and  other packages)  from any of the ftp arch sites. So I will try it later. I put the question about my problem on alsa bug tracker for now.  https://bugtrack.alsa-project.org/alsa- … hp?id=3053

Re: Microphone problem

Each time before getting the mic to work, I have to run KMix (KDE sound mixer). Increase the volume of "Capture Mux (mic), activate Input/Capture and increase the volume, and activate Switches/IEC958.

Re: Microphone problem

If you go to alsamixer, and unmute the mic and put the volume up, does it do anything. Cause mine did, but I wasn't getting any capture. So since that was the case. I muted the mic, pressed tab, made sure that capture volume was up and pressed space on both capture and mic. Thus you have a "Capture R L" on both the mic and the capture.
