How do i turn down my surround system on my

By loud noise I assume you mean in the movie you're watching or the CD you're listening to.
That's the protection circuit kicking in. Depending on how you have the player configured (audio levels, effects, mode....etc) it can "overdrive" the outputs and cause the protection circuit to energize.
If this happens a lot try changing the audio mode to something a little less (change speaker levels to a lower number, no bass boost or at least not as much, etc.).
Good luck.

If I understand correctly, you have a 3.5mm plug into your Samsung laptop, which is then connected to your Sony surround system via the red/white RCA plugs. I assume for the input to the Sony you're using a standard audio-in. I would check the speaker setup settings on the Sony to ensure that the "bass" and not just LFE (low frequency effects) are being sent to the sub-woofer. My understanding is that LFE is found only on Dolby or DTS encoded soundtracks, and if the subwoofer is limited to just LFE you wouldn't be getting any bass when listening to two channel stereo from your laptop.

I am wondering the same thing. I expected more bass when watching a movie but it seems the only way I can have lot's of bass is in Stereo mode, the rest of the settings do not have much bass. Hope we find a solution to this as I am disappointed at the moment.

The centre channel normally has the voices - sounds like it:

• isn't connected,
• isn't working or
  
• is turned down too far
• or the system could be faulty
  

No I haven't, but for me is the same.. Very poor bass, I'm already in week test and I'm thinking to return it.
Did you solved?

I UNPLUGGED THE SUBWOOFER SO THAT JUST HAD THE TWO SPEAKERS PLAYING

You need two more speakers to get surround sound,ie> two front one center and two for surround,then you need a home cinema amp to run the speakers and decode the sound from your tv,sky,dvd etc,and the sub gives you your bass.

Hope this helps.

CABLE GUY.

i have had samsung surround sound for couple months, only been used once, now when i power up, protect is displayed on front and then powers down, also, when it does work, sound is extremely low compared to when i first used it.

In my case, turning the surround sound OFF is what fixed the problem. The bass contibutes most to the perception of the location of a sound. If surround is ON without surround speakers connected, the internal TV speakers can only take the place of what would be the front speakers in a surround system. So turn surround OFF and set your bass preference wherever you want it. That worked for me.
