I solved my internal mic problem for Lenovo Ideapad U330 by doing all of the following: (Should work for Acer Aspire as well)
1. In terminal: sudo apt-get remove linux-backports-modules-alsa-`uname -r` 2. Get latest AlsaUpgrade script here, along with directions on download, compile, install: http://ubuntuforums.org/showthread.php?p=6589810 (It is AlsaUpgrade-1.0.23-2 as of 27Dec2010) 3. Download, compile, install AlsaUpgrade as discussed in #2. 4. After reboot, find out if you have installed the newer version of alsa. In terminal: cat /proc/asound/version 5. If mic still does not work, type: sudo gedit /etc/modprobe.d/alsa-base.conf 6. You should see something similar to: options snd-hda-intel index=-2 7. Add this to the end: options snd-hda-intel index=-2 model=XXXXX where xxxxx depends on your machine. Find out what you should put in xxxxx here: http://ubuntuforums.org/showthread.php?t=1043568 Acer Aspire user try adding "options snd-hda-intel index=-2 model=acer" 8. If your specific machine isn't listed, try using what is similar to your machine. For example, Lenovo Ideapad U330 isn't listed in http://ubuntuforums.org/showthread.php?t=1043568, but they do have other Lenovo machines listed and they are usually "model=lenovo". I added "options snd-hda-intel index=-2 model=lenovo" to the end of my modprobe file. 9. Save, exit, reboot. Mic works for me now and in skype. -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/412862 Title: AOD250 microphone problem -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
