Hi Danial. Thank you for taking the time to report this bug and helping to make Ubuntu better. I have found that you need to do the following to enable the built-in mic on a HP dv7:

1. Please ensure all "linux-backports-modules-alsa-" packages are not installed (They would only be installed if you have installed them - they do not get installed by default).

2. Install the "crack of the day" alsa-driver from https://edge.launchpad.net/~ubuntu-audio-dev/+archive/ppa Also ensure that you install the "linux-alsa-driver-modules-2.6.31" package from that same repository.

3. Edit the file /etc/modprobe.d/alsa-base.conf to be the same as http://ubuntu.pastebin.com/f34542f5d (Note that this is simply changing line # 42).

4. Do a complete shutdown, as a reboot does not seem to make these settings "stick".

5. Ensure that the correct channels are not muted using alsamixer (from a terminal window).

6. If the built-in mic is still not working, you may need to edit line 45 of /etc/pulse/default.pa to be the same as http://ubuntu.pastebin.com/f3b65d3a7. This may not be necessary in your case.

7. Do a complete shutdown, as a reboot does not seem to make these settings "stick".

If this does not resolve your issue, please attach your "/etc/modprobe.d/alsa-base.conf" & "/etc/pulse/default.pa" to this bug report so that I am able to help you further diagnose this issue.
Thanks in advance!

I am setting this to "Fix Released" as this hardware works as expected in the current development release (10.04).
