Ubuntu – restore speakers / headphones option


When I plug my headphones in after upgrading to ubuntu 12.04, it no longer mutes by speakers,and I also do not have a headphones output as I did previously.
I recall having to go into a conf file and disable FRONT PANEL AUDIO or something like that; and everything began to work fine. I have an HP DV6.

Is there anyway to see what my alsa-base.conf was before the upgrade?

Best Answer

I placed:

options snd-hda-intel model=hp-dv5

options snd_hda_intel model=hp-dv5

In my /etc/modprobe.d/alsa-base.conf

I don't know which syntax is the correct one, but I left them both in for good measure.

I did NOT restore my heaphones option, however it did mute the speakers when I plugged in my headphones and that was good enough for me.
