Public bug reported:
When I applied updates installing linux-image-3.2.0-65-generic, the
laptop headphones (sound system) stopped working. When I pull out the
sound-system plug, sound works through the (pathetic) laptop speakers.
Sound is at a reasonable level, and is not muted.
When I reboot with the former system linux-image-3.2.0-61-generic, sound
works through the speaker system as it always did before.
I am using an Acer Aspire 4339, running Ubuntu (Unity) 12.04.
I expected sound (audio) to continue working through my sound system
after applying system updates, but it didn't. The only way to get any
sound is to use the laptop speakers.
