It didn't work: sudo apt-get -purge remove linux-sound-base alsa-base alsa-utilsįor reference, here's the output from lspci -v | grep -A7 -i 'audio': 00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04) I also tried following the advice from a thread on Ubuntu Forums saying to remove and reinstall these packages, then reboot. DoneĮ: Unable to locate package linux-restricted-modules-4.4.0-47-genericĮ: Couldn't find any package by glob 'linux-restricted-modules-4.4.0-47-generic'Į: Couldn't find any package by regex 'linux-restricted-modules-4.4.0-47-generic'

I tried following but when I get to step 5 and run sudo apt-get install linux-restricted-modules-`uname -r` linux-generic

Now I have no sound whatsoever and in the Sound Settings menu the 'Default audio device' which appeared before under 'Play sound through.' has been replaced with 'Dummy output'.Īt this point I would be happy just to go back to the way things were before. configure then make then make install and rebooted. Since the other AskUbuntu solutions I found for this issue didn't work, I tried to install RealTek's linux codecs, as that is was is used in Windows.įollowing the instructions in the INSTALL file, I ran. I experienced the low audio volume issue, where sound is only about 25% as loud in Ubuntu as it was in Windows, even with all settings at their max (with sound > 100% enabled as well). I purchased a Windows laptop and replaced Windows with Ubuntu 16.
