No sound on Ubuntu 16.04 LTS on Dell Inspiron 14 7000

Asked by Mohit Bakshi

The original problem was that after suspending and resuming, there was no sound coming through speakers or headphones. After following step 1 on https://help.ubuntu.com/community/SoundTroubleshootingProcedure the sound completely stopped coming even after rebooting. My current setup is dual-boot and on booting to Windows 10 I found the sound wasn't working there either.

I followed through Step 3 and got this output - http://www.alsa-project.org/db/?f=e88bf97c4f87974cc3268307323b478c1dc1d875
On finding no driver version listed for alsa, I executed rest of the commands mentioned in step 3, rebooted and retested sound which still wasn't working

Output from step 4

Do you get sound in headphones?

No I wasn't getting sound in the headphones.

I solved the problem by doing a reinstall of alsa

sudo apt-get install --reinstall build-essential linux-headers-`uname -r` alsa-base alsa-firmware-loaders alsa-oss alsa-source alsa-tools alsa-tools-gui alsa-utils alsamixergui

sudo apt-get install.. did not work for me. So I tried forced install and it worked after a reboot
