[Bug 269294] Re: Acer Aspire 5520 cannot record sound with HDA-Intel NVidia Codec ALC268

[The Mike]

I fixed this problem on my Acer Aspire 5520 Notebook. I had the exact
same problems above, but can now record audio just fine with the
internal microphone from the Acer CrystalEye Camera and Microphone
combo.

NOTE: This problem was experienced in Ubuntu 9.04 and Linux Mint 7. The
fix was performed and tested in Linux Mint 7, which uses Ubuntu 9.04 as
its base.

Step 1:
Download <a href="ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.20.tar.bz2">Alsa drivers v10.0.20</a>

Step 2:
extract the contents.

<b>
tar -vxf alsa-driver-1.0.20.tar.gz
</b>

Step 3:
Compile the driver

<b>
./configure
make
sudo make install
</b>

NOTE: I actually used a program called CheckInstall which creates a
debian package that I can later install or remove at my leisure. If you
choose this option be sure to install CheckInstall first, and also it
may be necessary to install the finished package in this manner:

<b>
sudo dpkg -i --force-overwrite alsa-driver_1.0.20-1_i386.deb
</b>

Step 4:
Configure alsa-base.conf

Add the following line to the end of /etc/modprobe.d/alsa-base.conf

<b>
alias snd-card-0 snd-hda-intel
options snd-hda-intel model=acer
</b>

Step 5:
Reboot

Sound recording should now work correctly on the Acer 5520. I
experienced this problem with Ubuntu 9.04 and Linux Mint 7. The Fix
works in Linux Mint 7, and should therefore work in Ubuntu 9.04, as they
are essentially the same under the hood.
