Comment 76 for bug 783582

Ok, a new version of the patch has been produced by Takashi. This time it should always turn 0x1b and 0x1d on and keep it on.

I have also updated http://people.canonical.com/~diwic/temp/alsa-hda-dkms-acer3830tg_0.1_all.deb to include this patch instead.
Please test it (according to previous instructions: 1) no other workarounds installed, 2) download, 3) install, 4) reboot and 5) test) and report the result. Thank you!
