Yes, that would be correct. Add only "position_fix=1" to file "alsa-base.conf" in "etc/modprobe.d/".
I found that adding the other code, in my case, added noise to the microphone recording. I cannot confirm that as I had tried it twice and I cannot recall if it was a controlled test.
And yes, you may use my e-mail address if you wish as required.

Just to clarify, you only added position_fix=1, correct? Also, are you
okay with your e-mail being used in the Reported-by and Tested-by fields
for a patch to be sent upstream and to stable@?

Bug description:
Ubuntu 9.10 (RC - 20-Oct-2009 20:18)
Kernel Linux 2.6.31-14-generic
GNOME 2.28.0

Microphone does not work. I've tried every input on my computer. In the sound preferences for each input, I selected Microphone 1, 2 and Input to test every combination. I also tried recording using gnome-sound-recorder 2.28.1. A hissing sound was all that was recorded.

One other problem I've noticed since the Beta release into the current release is that when playing videos in Movie Player (Totem  Movie Player 2.28.1), the sound cuts off after the first video if running a play list or executing another video file while the Movie Player is running. In order to hear the audio portion, one must shut down Media Player and run it again to hear the sound. Media Player must be closed down for each file that is opened.

Here are my system stats:
