Internal mic not working in my UBUNTU 11.04 (64bit) in my sony vaio VPCEH3AEN laptop

Open a terminal (Ctrl+Alt+T) and send the output from this command:

sudo lshw -C multimedia

Still in the terminal run:

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

When asked if you want to upload it, say YES (y)

You will then be presented with a URL to where it was uploaded to … similar to:

Your ALSA information is located at [b]http://www.alsa-project.org/db/?f=d2144bd3c37d1583c0f59fb14a96d5838e42619f[/b]
Can you post that URL.

Now still in the terminal run:

lspci -vnn

In the output, look for any sections that contain “Audio device”, and post those sections.

here’s mine for comparison … so you’re looking for sections similar to:

00:1b.0 Audio device [0403]: Intel Corporation N10/ICH 7 Family High Definition Audio Controller [8086:27d8] (rev 02) Subsystem: Acer Incorporated [ALI] Device [1025:015b] Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at 78540000 (64-bit, non-prefetchable) [size=16K] Capabilities: Kernel driver in use: snd_hda_intel

Be aware, you’ll probaably have to scroll up in the terminal to find that section … and there may be more than one.

First thing to try …

Open a terminal (Ctrl+Alt+T), and run these3 commands in sequence:

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa

then

sudo apt-get update

then

sudo apt-get install linux-alsa-driver-modules-$(uname -r)

Now REBOOT … and check if your mic works.
