Setup Sony Vaio Laptop Internal Microphone Ubuntu 9.10 VPCCW17FX
The Sony Vaio VPCCW17FX uses the Realteck ALC262 codec and out of the box Ubuntu 9.10 the internal microphone does not work. However the mic input jack does work.
$ cat /proc/asound/card0/codec#* | grep Codec
Codec: Realtek ALC262
Researching on the web there were a lot of folks across a lot of distrubtions having issues with this codec with ALSA & Pulseaudio. Now I’m not a fan of Pulse Audio but I did get this to work without switching off Pulse.
As admin edited/etc/modprobe.d/alsa-base.conf to add the following line at the end :
options snd-hda-intel model=auto
Reboot and bring up your audio recorder to test!
