Public bug reported:
A similar issue mentioned elsewhere but with different hardware and
under different architecture.
When headphones are plugged into either or both of the two headphone
jacks the internal speakers are not muted. Using GNOME ALSA Mixer
dragging the "speaker" slider down will mute the internal speakers
whilst maintaining the current system volume to the headphones.
I have installed linux-backports-modules-alsa-karmic-generic and
rebooted. I have added "options snd-hda-intel power_save=10 model=hp-
dv5 enable_msi=1" to the bottom of my /etc/modprobe.d/alsa-base.conf
file and rebooted.
I have attached a copy of my /etc/modprobe.d/alsa-base.conf file to this
bug report.
