SoundTroubleshootingProcedure: hp dv8 intel sound not working.

Asked by daddmac on 2012-08-27

Many thanks in advance for the time and effort to review the following information.

I worked through the entire troubleshooting process before posting here, and the short version is that my sound card is not detected by alsa.

In all instances, I want to generate sound to the speakers.

aplay: device_list:252: no soundcards found...
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).

Step 8 information:
There is no sound from any output device, and no output devices were found by the applications.

Step 10 information:
There is no pulse-rt group, but root and my personal account are both in the other named groups.

Step 14 information:
There are no BIOS settings for the sound card as this is a laptop and there are no BIOS settings for it.

Step 17 information:
aplay: device_list:252: no soundcards found...

Subsequent Steps:
There is no asound folder under /proc (due to the device not being found), so that information is not available that I know of.

Again, thanks in advance for any information or links to help me get the sound working.

Driver version:
Library version: 1.0.25
Utilities version: 1.0.25

You have no alsa driver version, not good.

Try:

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install --reinstall linux-sound-base alsa-base alsa-utils; killall pulseaudio; rm -r ~/.pulse*

Wait 10 seconds and reboot. You may want to comment out the model line you added to the audio config.

Open a terminal and use the gedit editor to edit /etc/modprobe.d/alsa-base.conf as follows:

Run the following command in a Terminal:

gksudo gedit /etc/modprobe.d/alsa-base.conf

When the file /etc/modprobe.d/alsa-base.conf is open, please add the following 3 lines to the end of the file after "options snd-pcsp index=-2"

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=laptop

Please REMOVE the following configuration line in the /etc/modprobe.d/alsa-base.conf file:

options snd-hda-intel model=hp-m4

Save/close and reboot.

Then retest sound output using headphones and speakers.

Test sound output on all audio jacks at the front and back of your PC.

Make sure all channels are at 100% and unmuted in alsamixer

Mark and actionparsnip,

Thank you for your suggestions.

I implemented both suggestions and afterward all the tests I run say there is not sound card installed:
aplay: device_list:252: no soundcards found...

It appears that a Nvidia sound chip is also detected; should be trying to configure it instead of the Intel chip?

Again, thanks in advance.

Can you help with this problem?

Provide an answer of your own, or ask daddmac for more information if necessary.
