General assistance with K-lite please

Hi,
As posted in a previous post of mine, I am very new to K-lite and in general am loving it as opposed to other players, however some items are still confusing me somewhat, so I do hope I can get assistance here.
First, my PC specs:
Dell Optiplex 790 with 16GB RAM
Windows 7 64-bit
Nvidia GT 730
Generic C-Media discrete sound card with 7.1 capability
Turando 5.1 speaker system, connected with 3 analogue 3.5mm jacks
So, to my questions:
1: In the options, under output, is it better to choose directsound:speakers(C-Media PCI Audio Device or just Speakers (C-Media Audio Device? What is the difference if any?
2: Under External Filters, there are no entries in either of the boxes. Is this by design?
3: In the LAV Audio Decoder options, do I need to select the mixing option? The reason I ask is because if I do, the sound volume drops dramatically so I is unchecked at the moment. Also, what exactly does the mixing option actually do?
4: What function does the audio switcher perform? Does it need to be selected?
Below is my log generated by Codec Tweak tool in case it is needed:

1. Use directsound:speakers
2. That is normal.
3. Not needed. Your sound driver will then do the mixing instead. Mixing is changing the number of audio channels. For example from Stereo to 5.1.
4. It is for switching between multiple audio tracks. The player has ability to load a separate file for audio. Just ignore it. It most cases it does nothing, and also does no harm.

Wow, thank you so much for your reply and believe me this has helped immensely. I really love K-Lite (in spite of the detractors) and I am always trying to get the best out of it. I have one final question, except I MAY know the answer already, why is the volume when I play a movie or series so much softer than when I'm playing the sound from my TV (via single line in 3.5mm cable)? Is it because of the way the movie soundtrack was recorded, if that's the right word? Make no mistake, the overall volume on a movie is great, it just needs to be turned up a lot to hear, compared to the TV output. Is there a volume control somewhere in MPC-HC to increase the movie/series volume? Last question, I promise!!! LOL

If the relative volume between the different sounds in the soundtrack is normal, then a difference in volume level on the TV could be simply because of more powerful speakers (more watts).
Since the TV probably has stereo speakers, the 5.1 gets mixed to 2.0 and that could also give higher overall volume depending on how it is mixed.

Two settings that you can try:
MPC-HC options > Internal Filters > Audio Switcher > Boost and Normalize

Boost will increase volume of everything. Setting it too high could potentially result in overflow (volume > 100%) which can harm sound quality.

Normalize reduces dynamic range, which means it reduces the difference between soft sounds (voices) and loud sounds (explosions). This generally also increases the overall volume. Try this first, you may like it.
