Ubuntu
alsa-driver package

No audio from Ubuntu 16.04 with intel realtek sound card (laptop asus x555u)

Asked by Hugo

This was not always happening, and may have occured after unplugging an HDMI cable but I do not remember exactly when It happened. I have tried various things, so I am not surprised if my sound drivers configuration is a bit of a mess.

Following the SoundTroubleShootingProcedure (https://help.ubuntu.com/community/SoundTroubleshootingProcedure) now on step 3 it advises me to share the output of the alsa diagnostic command.

The alsa diagnostic results: http://www.alsa-project.org/db/?f=1fa6476ad01d162d772fad0a1ca9a10700bfa2de

The alsa driver version is: k4.4.0-101-generic

I appreciate any assistance with getting my sound up and running again, regards.

Things I have tried include, installing/restarting pavucontrol.

Killing pulseaudio, removing its files at ~/.config/pulse/* and ~/.pulse*

Raising all volume levels, in the alsamixer.

Do you get sound in headphones?

Thanks

Just tried headphones, no sound comes through them either.

Please first try this solution (setting model option auto in the /etc/modprobe.d/alsa-base.conf file):

https://elementaryos.stackexchange.com/questions/8738/asus-x555ub-realtek-alc256-no-sound

An alternative would be to test Ubuntu 17.10 in a LiveUSB session in order to check if audio works out-of-the-box in Ubuntu 17.10...

If you are dual-booting with Windows, make sure to fully shut down in Windows instead of rebooting or hibernating your Windows session.

Thank you very much Mark, I should have found that solution, but I suppose I was barking up the wrong tree with the search keywords I had used before. Thank you as well actionparsnip for your suggestion.

To be clear Mark's link, to the stackexchange.com solution, was what fixed my problem. The code that I ran from that link I am placing below:

sudo apt-get update && sudo apt-get upgrade

echo options snd-hda-intel model=auto | sudo tee -a /etc/modprobe.d/alsa-base.conf

sudo alsamixer

shutdown -h now
