Audio doesn't work after boot from Windows

[Joshua Muzyka]

For some reason my audio doesn't function after I boot into Windows 7. I'm running a dual-boot system with Win7 and Ubuntu 12.10.

Ubuntu does not start pulseaudio on boot. I press alt+F2 to run pulseaudio and audio begins to work. Then when I restart the computer and log into Win7 then shut down and revisit Ubuntu 12.10 my audio doesn't work even after starting pulseaudio.

Output of lspci:

Aspire:~$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)

Output of aplay -l

Aspire:~$ aplay -l

I have experienced this problem since 12.04. Issue occurs with Windows XP or Windows 7. I do have a workaround. Suspend Ubuntu and power on. Sound returns.
