The XPS 410 and E520 are essentially the same system, so this issue affects both.

Front and rear mics are not working in ubuntu gold 7.04 desktop. (2.6.20-15). Front speaker also not working, but rear is ok.

Both mics and speakers connection were working correctly in 7.04 beta with the 2.6.20-12 kernel.

Found this patch from late March specific to the E520: http://git.kernel.org/?p=linux/kernel/git/bcollins/ubuntu-feisty.git;a=commitdiff;h=de4755b3b5e905194d9a9d06eb86a9200c28c864

Not sure why it was added, but this could be what is causing the problem. Was there a specific reason this quirk was added to the tree for this system?
