I just installed elementary OS luna. At first, it seemed like the sound worked fine even when I was plugging my headphones or my external speakers. However, after I installed all the updates, the sound no longer works when my headphones are plugged. My laptop speakers work however. This used to work fine two months ago when I tried the first beta of luna, so it must be a regression since I never had this problem in Ubuntu with the same computer. Also, it's not a hardware problem since the sound works fine in Windows.

After some updates there was no sound on the headphone jack. I can raise everything alsamixer to hear a silent sound.
I cannot raise the headphone control. It is not muted.
I have changed to the latest kernel, but the bug still exists.
