OK. Let's see how this might help some of you to understand what I've done.
First at this point I am using
VIA 10600a drivers. This is important. I have them from
here.
Second, the player migh play an important part so I'll put it as well. I am an old user of KMPlayer and after the team dropped the suport on it to develop PotPlayer, I have that. You can get
PotPlayer from
here.
Do not download the DirectX or whatever it might complain about.
PotPlayer will ask you for a speaker setting. You can choose whatever you want, it can be changed later.


There is also a LFE setting that will give you a bit more low freq.
If other settings are checked in this section, make them to be like mine or test your own to suit your needs.
I find PotPlayer to be a very nice program for music and movies. It has internal codecs, uses full GPU power when needed, is low on system resources, has a ton of options, it's very stable. The bad part with the x64 version is that it will minize to tray everytime.
The VIA Deck settings:
Volume control - I set Bass Filter to 50.

Speaker setting

Default format - programs might use different settings, so I didn't change a thing here.

Sound Equalizer - the part you all want.

Here are the values for them:
60 = +5 - there is hardly any improvement on low freq. with this any higher.
170 = +15 - Sub and speakers both are affected by this.
310 = +5 - higher value will not help sound quality much.
600 = 01k = -10 - Sub and speakers both are affected by this, for a Sub a range 'till 1k is quite a lot.
3k = 06k = +1012k = + 15 - Above 12k sound quality on speakers will be poor.
14k = 016k = 0If you have questions, please ask.
I did not change anything in Windows.
