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?
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.
In a terminal execute alsamixer then with the arrow keys go to the column "Auto-Mute", once selected set with the up arrow the option "Enabled".
Seems like the interface to my alsamixer is a bit different, but using the M key on my speaker changed a previously mysterious (grey-ed out) MM to ungreyed out 00 and re-enabled the speaker. The secret was definitely alsamixer.
I was having the same problem...
I updated from Ubuntu 11.10 to 12.04 and my frontpanel stoped working. The sound was only coming out from the rear panel.
I opened the terminal, typed alsamixer and pressed ENTER
Inside the Alsa mixer, I pressed right arrow until I get to an option called "Loopback Mixing". It was disabled... Enabling it solved my problem.
Hope it solves to you too!
Add ppa:diwic/hda repository to your sources
Are PPA's safe to add to my system and what are some "red flags" to watch out for?
sudo apt-add-repository ppa:diwic/hda
sudo apt-get update
sudo apt-get install hda-jack-retask
Run hda-jack-retask from terminal
check set model=auto
click install boot override
reboot and you are ready.
tested on ubuntu 12.04 with realtek alc888 chipset.
