I have an acer aspire 722, I recently went to use gmail/talk as well as empathy and realized that the microphone does not work. I checked the sound settings, adjusted microphone level, did a mic test but the level indicator showed no bars.

Now my speakers work & mic work:
- I installed
linux-image-3.4.0-999-generic-pae_3.4.0-999.201205070447_i386.deb
- and then adjusted mic boost in alsamixer
sudo alsactl store
- added to startup applications:
alsactl restore
-

linux-image-3.4*
? All that's available to me is up to 3.2 in Precise. Aug 27, 2012 at 5:30 -
in precise, you can usually install newer kernels through the hardware enablement stack because precise is LTR– mchidNov 28, 2015 at 21:26
You need to unmute the microphone input. Try running alsamixer
in a Terminal window (Ctrl+Alt+T), and checking it there. If it's muted or low, you can unmute and/or increase it in alsamixer
.
- Open a terminal window by pressing Ctrl+Alt+T and type:
alsamixer
. - Press F6 and choose 1 HDA ATI SB as a sound card to configure by pressing Enter.
- To see the mic-related sliders, press F5 and move the cursor keys to the right, only the outermost three sliders need to be set to a level of 56 by pressing the Up key
- Then, by pressing the C key on each of the three sliders, the volume level of each right channel needs to be put to 0
- finally, quit alsamixer by pressing ESC.

After each reboot, you may need to toggle the Mute button by:
- Click on the speaker icon on top right panel and choose Sound Settings...
- Click on the Input tab (second from left) and adjust input volume to Unamplified 100% and say something to see if the input level indicator moves enough. If not, click on Mute to mute and then click again to unmute.
Hope this helps
