So I recently installed Ubuntu on my second HDD in anticipation for Steam on Linux, but came across a problem concerning 5.1 surround where my subwoofer wouldn't work properly. If I tried to play an MP3 file, I'd get no bass whatsoever. Pausing the song and clicking on the "Analogue Surround 5.1 Output" option in my sound settings fixed the problem temporarily, but as soon as another song started playing, I'd get no bass again. After doing a bit of research, I was able to discover the following fix...
Firstly, make sure your sound settings are correctly configured. Set the mode to Analogue Surround 5.1 Output as mentioned earlier. It should look like this...
Next, you'll want to open a terminal and enter the following;
gksu gedit /etc/pulse/daemon.conf
Scroll down until you find the following line...
; enable-lfe-remixing = no
... and change it to this, making sure you don't forget to uncomment the line;
enable-lfe-remixing = yes
Save the file, return to your terminal and enter the following command;
killall pulseaudio
Once the command has executed, try playing some audio. You should find that your subwoofer is working once again!

Besides, this might help someone :thumbsup:
Install Windows Audio Driver
Go to Audio Player.
Play the song.
It should work.
If you have a 5.1 System and using Realtek Chip.
Boot up Windows it will automatically installed the new driver or you can download it from majorgeeks.
Install and restart.
Go to the Realtek Sound Panel, select 5.1, test the speakers one by one, enable speaker fill and go to Room Correction to manually play with DB levels.
Also, avoid Bass Management. Use Cyberlink PowerDVD Ultra Mark II with True Surround to have fun with 2 channels file or just select stereo when playing MP3 files.
Also, select Dolby Surround (Force enable) in VLC to get the best sound possible. FFDshow Audio mixer works as well.
Incidentally, i've also started using the latest Ubuntu. It's better and finally usuable for more then ten minutes.
The most important part of this is probably enabling the speaker fill. I remember having problems getting my 5.1 to work properly as I had no center/subwoofer channel. After enabling speaker fill I had to restart and it all started working. Not sure if this is a problem for everyone, but it has been totally fine ever since :thumbsup:
I tried using Alsamixer to get things working but I couldn't fix the problem. It's a handy tool though, fo sho. The new Ubuntu is actually pretty nice. They've fixed Unity! It now runs on my dual-screen setup without any problems. I wish I could get the launcher bar to sit on the right hand side of my monitor though... Do you know how to do that? (Before I google it )
Does it fix my need to move the launcher bar? I'll check it out, thanks bro!
