Using the same computer with Windows 8 and Ubuntu I noticed that the sound was worse in Ubuntu and I discovered why soon: subwoofer doesn’t work out of the box!
How to fix it
The fix is quite easy to apply (but it was not easy to find the right one!). First of all edit /etc/pulse/default.pa and add this line at the end:
load-module module-combine channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe
then edit /etc/pulse/daemon.conf, modify the line “enable-lfe-remixing: no” to “enable-lfe-remixing: yes“, then uncomment it (remove the semicolon in front of it). Reboot your PC and enjoy the subwoofer!
I admit. This website, like thousands of others, has been hacked! I still have to identify the precise source of the attack, but I’ve found out that is very common. I was able to discover about the attack just because the dashboard of WordPress stopped working. I decided to investigate and I found this strind on top of every .php file http://pastebin.com/k0iQymRy
Just googling I discovered that I was not alone http://stackoverflow.com/questions/16963818/server-hacked-on-wordpress-files
How to fix this?
The best solution would be to restore the files with a valid backup, but sometimes this is not possible. Here comes an handy bash solution (note: you need to be able to access your hosting with a SSH shell to execute this command): http://pastebin.com/V3nFwwtZ
