I'm on Ubuntu 14.04 and when i booted it the sound was working. But it wasn't working the way it does on Windows 7, like in it there is a feature for me to use Dolby Technology to create really nice sound. On Ubuntu, it just really bad just 'treble?" and no bass. It doesn't even use the subwoofer present on my laptop.
So I tried installing this [extracted, complied, install make]. Used the Linux version. It just completely broke the sound system on my laptop. NO more sound or anything.
I did this too from a thread I found,
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils sudo apt-get install linux-sound-base alsa-base alsa-utils
It didn't to anything. Now I ran this command
wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && bash alsa-info.sh --upload
and this is its output.
My laptop is Qomsio F 50-126 with builtin Subwooder and two speakers and running Ubuntu 14.04.
