[Bug 1408856] Re: [HP Pavilion dv6700 Notebook PC, Realtek ALC268, Speaker, Internal] No sound at all

 

OK, after no help in finding how to install the suggested program, and a
lot of fruitless searching I finally stumbled acros :

https://launchpad.net/~diwic/+archive/ubuntu/ppa

More specifically you need this :

https://launchpad.net/~diwic/+archive/ubuntu/hda

To install do the following :

sudo add-apt-repository ppa:diwic/hda
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install snd-hda-tools

Once I ran it I got the following, if it makes any sense :

sudo hdajacksensetest
Pin 0x15 (Black Headphone, Rear side): present = Yes
Pin 0x18 (Black Mic, Rear side): present = Yes

Ironically the laptop has a pair of sockets at the front for headphones
but no actual ´rear´ ones.

It seems that whether the headphones are plugged in or not the system
believes that they are, and that the internal speakers are therefore
´disconnected´

WIll happily diagnose/test further if someone tells me what to do.

Title:
  [HP Pavilion dv6700 Notebook PC, Realtek ALC268, Speaker, Internal] No
  sound at all

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  Sound won´t work on default install on internal speakers or
  headphones.

  Downloaded Realtek driver, compiled and installed and still no sound.

  Compile command

  ./configure --with-cards=hda-intel

  Rt-Linux-HDaudio-5.18/alsa-driver-RTv5.18

  Clearly some thing is happeing as the volume controls work, and in
  pulse volume control it shows varying volume on the meters.

  Analogue Stero shows ´Speakers not connected´
