speakers work only after resume

[mmicotti]

Hi

since the 11.10 version of Ubuntu I have this problem: when I start my notebook, speakers do not work, whereas headphones do.
After standby and resume, usually but not always, everything works well.
Any ideas?

Thanks!

some information about my notebook

Ubuntu 12.04 LTS 64bit (fresh installation)
HP Elitebook 8440p

the output of aplay -l is the following:

Finally I fixed it.

I followed the instruction of the last post of this thread: http://www.linux-archive.org/gentoo-user/566518-ff-chromium-trapped-deafness-how-configure-alsa-correctly.html (linked by this other one: http://www.linuxquestions.org/questions/slackware-14/slackware-13-37-audio-setup-seems-fine-no-sound-922521/), and I set the last line of alsa-base.conf as follows:

options snd-intel-hda model=auto,auto enable_msi=1,0 index=0,1 id=Intel,NVidia

After shutdown (simply rebooting do not work, I don't know why) everything seems to work fine..
