Comment 22 for bug 25634

2 month ago I faund way to make sound works after plugging/unplugging phones, boot and suspend.

The reason was in /etc/apm/scripts.d/alsa.

Now it works for me. Hope patch in attach helps U.

As a bonus in patch added feature to almost instant sound off then close notebook and go to sleep, as it made in Mac OS X.

To try it:
cd /etc/apm/scripts.d
sudo cp alsa alsa~
sudo patch alsa alsa_suspend.patch
