Internal Mic on HP 6730b not working

Hi asif,
Please try installing "linux-backports-modules-alsa-karmic" (then reboot). A number of audio problems on HP laptops have been resolved by installing this package. Also please ensure there are no extra "alsa model quirks" in your /etc/modprobe.d/alsa-base.conf

Also ensure that your mic is not muted in alsamixer.

If this doesn't resolve your issue, please file a bug & link it to this question for me to be able to help your further.

This is how my alsa-base.conf file looks like
http://pastebin.com/f2184e945. I won't be able to tell if there is any
extra "alsa model quirks" sitting here

Also ensure that your mic is not muted in alsamixer.

How can I tell if it is muted or not?

I followed your steps and now it is working! Excellent! thanks a lot

Now I can record using Sound Recorder and can playback fine.

It even works in my VM windows.
