Ubuntu – Beats audio driver for hp dv6-7040tx

Take an example for 12.04 amd64 arch. I recommend 12.04 LTS instead of 13.04. 12.04 are more stable than 13.04 and will get supports until 2017. Some PPA like ppa:ubuntu-x-swat/x-updates and ppa:ubuntu-x-swat/intel-graphics-updates do not offer to 13.04 now.

Do NOT take care of "additional drivers" for graphics card from ubuntu software center.

You first need to set graphics cards to 'switchable' in bios, if there has the setting item . If there no, do not care.

For your notebook , you should use bumblebee:

sudo add-apt-repository ppa:bumblebee/stable
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia primus-libs-ia32
Ref: https://wiki.ubuntu.com/Bumblebee#Installation

Then If you want to run application with Nvidia Graphics Card, you only need to run 'optirun xxx' in gnome-terminal.

You can also make use of HD4000 for mplayer:

sudo apt-get install i965-va-driver
sudo add-apt-repository ppa:sander-vangrieken/vaapi
sudo apt-get update
sudo apt-get install mplayer-vaapi
Last, change video output driver to `vaapi` in `Gnome Mplayer` or `VLC` config.

In order for ubuntu to know your intel graphic card in 'System Settings'-> 'Details', you need to run:

sudo apt-get install mesa-utils

You can also try intel SNA (the new 2D acceleration technology for the Intel graphics driver):

sudo add-apt-repository ppa:ubuntu-x-swat/intel-graphics-updates
sudo apt-get update
sudo apt-get dist-upgrade
sudo mkdir /etc/X11/xorg.conf.d/
echo -e 'Section "Device"\n Identifier "Card0"\n Driver "Intel"\n Option "AccelMethod" "sna"\nEndSection' | sudo tee /etc/X11/xorg.conf.d/20-intel.conf
Then restart machine.

The model=ref method doesn't work quite right, at least not on my laptop. You have to remap some HD audio ports that appear disconnected and then all the speakers work. There's a convenient little tool out there that does just that. I also got it working under Debian and it works without breaking headphones too.

Step 1: Install hda-jack-retask from here: https://launchpad.net/~diwic/+archive/hda (ppa:diwic/hda)

Step 2: Open hda-jack-retask

Step 3: Select the IDT 92HD91BXX codec (may be different on other models)

Step 4: Check the "Show unconnected pins" box (the internal speakers do not show as connected)

Step 5: Remap 0x0d (Internal Speaker, Front side) to "Internal speaker"

Step 6: Remap 0x0f ("Not connected" but is the under-display speakers) to "Internal speaker"

Step 7: Remap 0x10 ("Not connected" but is the subwoofer) to "Internal speaker (LFE)"

Step 8: Apply now, then test with your favorite audio program (some may not work due to Pulse reset, so find one that does, verify sound is coming from all speakers).

Step 9: If it works, select "Install boot override" to save the settings to apply at boot time.

Step 10: Reboot. When it comes back, you should have full sound from all speakers. Also test headphones. Plugging in headphones should disable sound from all internal speakers.

From Ubuntu 13.10, hda-jack-retask is part of alsa-tools. Just install the alsa-tools-gui package from the regular archive and start "hdajackretask".
