Comment 6 for bug 585858

Hey, I'm using the Samsung N210, which also has the Realtek ALC269.
I had the same problem, played around with the HDA Analyzer and finally get it fixed. :)
What you need to do:
1. sudo -s wget http://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-verb/hda-verb-0.3.tar.gz
2. Unpack hda-verb-0.3.tar.gz
3. Compile and install it.
3.1. cd hda-verb-0.3
3.2. make
3.3. sudo cp hda-verb /usr/bin
4. Open /etc/rc.local in an editor as root. (e.g. sudo gedit /etc/rc.local)
5. Add the following line:
/usr/bin/hda-verb /dev/snd/hwC0D0 0x19 SET_PIN_WIDGET_CONTROL 0x24
5. Save it and restart.

No warranty, but since it's the same codec, it's very probable to work. :)
In hope of a good response. :)
