Comment 32 for bug 731706

Hi! Sorry to reopen such an old thread...Running Ubuntu 11.04 (2.6.38-14-generic amd64) on a Dell Studio 1555 laptop. Internal Mic array not working. It used to work perfectly on 10.10. Not getting ANY input device in alsamixer. Did everything this thread suggested as well as this on (http://ubuntuforums.org/showthread.php?p=11921578#post11921578) .
