[SEMI-SOLVED] internal mic not working

Postby bewilderness on Sun Jun 05, 2011 3:25 am

Hi! I'm a newb who recently downloaded Linux Mint only to find that the system does not detect my microphone!
I looked under Sound Preferences and there is no options under "choose a device for sound input" ...I know I have a microphone because it was working under Windows...

Also, in pulse audio (I downloaded pavumeter because it worked for someone else's problem) under recording it says "no application is currently recording audio" ...

The following is my output of lspci:

Thanks in advance for any help.

I forgot to mention: you can also type alsamixer in the Terminal and adjust the sound controls. Use left and right arrows to select a sound control, up and down arrows to adjust the volume, press M key mute/unmute. F6 to select the sound card.

I have just remembered. My friend had the same problem with his Gateway MD2614u. He did this and it worked:

run in the Terminal:
sudo gedit /etc/modeprobe.d/alsa-base.conf
and added

options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes

to that file.
*Don't forget to save the file before you close it and restart your computer. Please let me know if it works.

Re: another with the same [SOLVED] internal mic not working

Postby sdibaja on Wed Jun 15, 2011 11:01 am

I have the same problem that bewilderness had...
I have a Sager NP8170
00:1b.0 Audio device: Intel Corporation 6 Series Chipset Family High Definition Audio Controller (rev 05)

I tried opening a terminal and running: sudo gedit /etc/modprobe.d/alsa-base.conf

that did open the alsa-base.conf file in a text editor.
I pasted in:

options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes


at the end of that file, saved, and rebooted... no change.

I do note that this was at the end of the file:
# Ubuntu #62691, enable MPU for snd-cmipci
options snd-cmipci mpu_port=0x330 fm_port=0x388
# Keep snd-pcsp from being loaded as first soundcard
options snd-pcsp index=-2
# Keep snd-usb-audio from beeing loaded as first soundcard
options snd-usb-audio index=-2


am I being dense or too literal?
Thanks, Peter

It took me awhile to realize this, but I'm having a problem with my mic still not working with Pulse... it works with ALSA.... I think they're different. Not sure.

Peter-- I also have the same last few lines in that file.

alsamixer shows this:

F6 gives me this:

selecting either card with the arrow key and pressing enter does nothing, I have no idea how to activate

I had to do all that to get mine working too.

But I had to do this also:

From my Linux Book of Shadows. lol

Acer Aspire One 532h Microphone
Got the microphone working.
In terminal: [Type]

sudo apt-get install pavucontrol

Go to: pavucontrol [PulseAudio Volume Control in Menu]
Then: Click the "input devices" tab. Click the lock icon to unlock channels. Set the front right channel to silence.

[SOLVED] internal mic not working

Postby sdibaja on Sat Jun 18, 2011 6:17 pm

I resolved my issue withe the internal microphone not being listed as an existing device... I reinstalled Mint 11.

BTW: I am sure glad I was advised to create a separate /home folder, saved a lot of work and most all settings are still recognized and active.

I followed all the steps, but my result was that I lost any sound. I cannot listen to my music anymore or nothing, the sound just disappeared. What do I do?

This WORKED for my Acer Aspire One D250 microphone too... BUT do we have to do this left/right channel thingy all the time? In fact, what in the world are "front left" and "front right" referring to??

Why is microphone not a straightforward slider in Volume Control??

I hope you can enlighten me, thanks!

This also worked for my Asus EeePC 1005P. I do agree with @rykel88 though, it's a messy and slightly weird solution.

It worked for me - thanks, wyrdoak. I updated Ubuntu troubleshots https://help.ubuntu.com/community/Sound ... leshooting (section "Increasing very low microphone input") and https://help.ubuntu.com/community/HdaIntelSoundHowto (section "No mic working, rest OK") and posted on Polish Debian forum too http://debian.linux.pl/threads/25404-Ja ... post145845

P.S. Looks like more people might have an issue with two channels, of a microphone, that conflict resulting in low microphone input signal http://debian.linux.pl/threads/25426-Mi ... post145912

Hello! Thank a lot.
I`m new to this. But I work maybe one year ago with linuxmint. First in a Acer Aspire. And now with Medion MAM2100.
I have installed LinuxMint Release 10 (Julia) and had the same problem with the microphone, and I tried this and problem solved.
Salud!

That's what I have to do on my Asus Eee 1001P and on Skype I also have to remove the mixer control in the Skype sound settings.

Re: [SEMI-SOLVED] internal mic not working

Postby aga on Wed Oct 31, 2012 6:55 pm

Working on friend's Acer Aspire One 722, on Mint 13.
Been doing lots of research with 'fixes' but, while I've made progress, there is still a problem with the internal mic.
The situation now is that, using Audacity, the mic volume is low, accompanied by lots of background noise. If I increase the volume setting, the noise and signal both increase.
Silencing one channel doesn't help or make any real difference. I tried the patch to invert one channel, but the expected option in Alsamixer didn't show up. Zooming in on the waveform, the two channels are in phase. I've added the patch to the driver, to the modprobe and to the alsa.conf with no difference.

Please, does anyone have any bright ideas?

Thanks
