Only dummy output as sound system, no soundcards showing

Asked by Dimitris Mitsis

Hi everyone,

Currently using Ubuntu 16.04 in a Lenovo Y50-70

I have this issue since 15.04 and I have tried every solution possible.
I can only see the dummy output as a sound device -> alsamixer
(also I should add that the only thing that works is my usb headset which thankfully allows me to work)

I'm begging for your help although I'm letting you know that this is caused by myself trying to configure the system beep and not from an update.

This is the output of the step3 of the SoundTroubleshootingProcedure:

and this is the output of the Step 4:

Thanks a lot in advance!

The mini jack port of the laptop isn't working.

The only way I have sound is through my USB wireless headset because it appears as another device.
When I connect this, I can see the headset in the list of sound devices.

Your Terminal output shows at least 2 issues:

1) Library version: 1.0.16
Utilities version: 1.1.0

ALSA library and utilities versions are not the same. They should be.

Try fixing this by running these Terminal commands:

sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily

sudo apt-get update

sudo apt-get install linux-image-extra-`uname -r`

sudo apt-get install --reinstall linux-image-extra-`uname -r`

sudo apt-get install oem-audio-hda-daily-dkms

2)

snd_hda_intel: model=generic
snd_hda_intel: beep_mode=2

So maybe your sound card does not like the fact that you configured the alsa-base.conf file using model option generic.

I suggest replacing model=generic with model=auto. Remove the beep_mode=2 parameter from the file. Save the change.

Then reboot and retest sound output using headphones and speakers.

Make sure that audio is enabled in the BIOS.

Make sure that the volume is unmuted and set to 100% on ALL mixer channels in the alsamixer command line tool.

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

Thanks a lot Mark for your detailed answer :)

Unfortunately, this didn't help me resolve my issue so since I had caused this myself I had to format my pc and perform a clean setup of Ubuntu 16.04. This resolved my issue.

Thank you very much either way!
