I installed 12.04 today.
It worked on 11.10.
Now if headphones was plugged in on startup, they works, but if I unplug it, speakers don't work.
If headphones wasn't plugged before startup, sound is in speakers and in headphones at the same time.
Laptop is Acer aspire 5930.
Card: HDA Intel
Chip: Nvidia MCP77/78 HDMI
riad@riad-laptop:~$ cat /proc/asound/pcm 00-00: ALC888 Analog : ALC888 Analog : playback 1 : capture 1 00-01: ALC888 Digital : ALC888 Digital : playback 1 00-02: ALC888 Analog : ALC888 Analog : capture 1 00-03: HDMI 0 : HDMI 0 : playback 1
Same problem in 12.10dev
Which additional info should I provide?
