Internal microphone on Lenovo G570 with Ubutnu?

[Marzata]

The internal microphone doesn't work on brand new Lenovo G570 with Ubutnu 11.04. Any idea how to fix it? The external microphone works perfectly when connected. Thank you!

Any idea?

I have the same problem with my Lenovo G570.

I've solved it!.

You must edit /etc/modprobe.d/sound.conf

options snd-hda-intel model=asus

I'm using Kubuntu 11.04, and I had "model=thinkpad" by default. Changing to "model=asus" and reboot alsa with:

sudo alsa force-reload

Note: Sometimes, when I've tried to reload service alsa, it failed because pulseaudio was working. Reboot and go.

You could test it with:

arecord -D hw:0,0 -vv -f cd ~/test.wav

Thank you for your answer. I am running Xubuntu 11.10 and
/etc/modprobe.d/sound.conf
is empty.

You must be sure that the module is loaded correctly:

$ lsmod | egrep snd_hda_intel

If the module snd_hda_intel has been loaded, you could create the file /etc/modprobe.d/sound.conf if it does not exist, or add the line if it is empty.

Thank you! The internal microphone works now. Is there a way to turn it up? Thank you again!

You can change volume levels with:

$ alsamixer

[Marzata]

There in alsamixer I am not sure what should be the mic control. See the attached screenshot. Thank you!

Hi Marzata!

my internal mic control is "Analog Mic Boost". I can turn it up to 40dB. In your screenshot, it is on 30.

But my Chip is Conexant CX20590. Yours is "Intel CougarPoint HDMI". Is it the graphic card? On alsamixer, you can press F6 to select sound card.
