View Full Version : [kubuntu] dv8t - sound plays only through speakers

So, I have an HP dv8t and I'm running Kubuntu 11.04. I ran it off of the Live CD first to see if I had any problems before I installed, and I'm glad I did, because I ran into one.

The sound either plays through the speakers and the headphone jack or not at all - Ubuntu doesn't seem to want to mute just the speaker channel. I searched the forums and found this link:

Unfortunately, none of those suggestions work. Does anyone have any ideas on how I might fix this?

You probably just need a model keyword in /etc/modprobe.d/alsa-base.conf. Something like:

echo options snd-hda-intel model=hp-dv5 | sudo tee -a /etc/modprobe.d/alsa-base.conf
..and then restart ALSA:

cd /usr/sbin
sudo alsa force-reload
