How to get microphone to work on acer aspire one 722

Question

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.

Answer 1

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

Answer 2

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.

Answer 3

• 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
