Ubuntu – Fix Internal microphone issue on Lenovo G570

28. January 2012 SysAdmin 0

Some times the internal microphone doesn’t work on brand new Lenovo G570 with Ubutnu 11.04
You can fix it with these steps.

#sudo gedit /etc/modprobe.d/sound.conf

Then add these lines and save the file.

options snd-hda-intel model=asus

If it has these lines already, then please replace the model=thinkpad with model=asus
Now reload the audio driver by running,

#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 by running.

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

Press Crtl+D to exist. Then play ~/test.wav with any audio player.
You are done !!! Thanks.
