So I got these speakers today from b grade 2 speakers are messed up pretty bad and sub I scuffed but hey chance you take, I've tryed to connect them up to tv but as I know nothing about sound and the connections I don't know what to do any help

I've got optical cable from tv into speakers atm but nothing
 
1) read your TV manual* about making sure the TV's Optical output is set to PCM

2) make sure cables are full inserted and check that your speaker kit remote has working batteries

3) Use the speaker kit remote to select the Optical input. Put the TV on to a Freeview channel. Increase the speaker volume

If the above hasn't given results then go back and recheck your settings and connections. If you have another source (Tivo will do) then try connecting that to the speakers instead of the TV as a second test.

After that it's time to look if there's a faulty optical cable. After that then check another input on the speakers just to see if you can get any sound at all. If the speakers are refurbs then there could be issues that you or the store weren't aware of.




* lost it/can't be arsed finding it - Go to maker's web site, download, read
 
They work I tryed aux to red/white and they worked I can't get free view channel as I don't have anyway airial so don't know how to get sound from tv/TiVo to speaker
 
All of the devices in the chain need to be passing audio in a format that the speakers understand. That format is the digital version of stereo on red and white phonos. The digital version is called PCM. With most devices there's only two choices for digital audio. These are either PCM or Dolby Digital. The format you want to select is PCM. Read your TV and Tivo manual about selecting PCM as the audio option.

Now just go back and follow pots 1 - 3 in my first post. As long as you know for sure you selected the optical in on the speakers and they responded correctly the set the telly to watch Tivo, make sure something is playing and the turn up the volume. If still no sound the either the lead is broken or the optical input on the speakers is bust.
 
So I've set my TiVo box to change sound from Dolby to pcm, my tv is set to pcm I've tryed putting optical from tv to speakers and 0 luck also tryed TiVo to speakers 0 luck :(
 
So when you've used optical from the TV and gone through the inputs, you've got nothing?

On Microlab's site, it says PCM among the specs. SPDIF though, only supports stereo PCM. There's not enough bandwidth for any more than two channels, that's why Dolby Digital and DTS are needed to compress the audio channels so 5.1 can be sent via SPDIF.

In the specs there is no mention of Dolby or DTS, so how can the speaker system receive 5.1 from digital source, such as a DVD player or console?

If it only accepts PCM when using digital input, it still needs to be upmixed to 5.1. Majority of 5.1 systems use Dolby Pro Logic II to upmix stereo to 5.1, but Microlab haven't mentioned Dolby at all, so I'm wondering what they have done in order for that to work.
 
Well, regardless of how these speakers process stereo PCM into 5.1, one thing is for certain: If the TV and TiVo box are outputting PCM, then it should work once the correct input has been selected.

Maybe get a cheap optical cable to try if you don't have a spare one, just in case the fault lies with the included one. If the fault doesn't lie with the included cable, there might be a fault with the digital processing components. They aren't used when you use analogue input, which seems to work OK.
 
Just decided to RMA it if it's a fault with the things I recieved I'm not willing to spend more money as it was b grade it was scuffed to speakers where in really bad condition but was going to use these behind my sofa so wasn't bothered but now as more problems have come about im just not satisfied and decided to return

That's pobably the most sensible solution.

5.1 PC speaker kits never really cut it as a TV audio system. Unless you're paying £250+ for the Logitech z906 then so very few have proper DD/DTS decoding chips or even basic genuine ProLogic decoding. In fact, in many cases you're lucky that this kit plays through all 5 surround speakers when presented with a stereo source.

That's not surprising really. The licensing fees for those two decoder chip sets would make PC speakers far more expensive. I doubt many folk who don't know what to look for would care much, and the higher price would put them off.

Vague Chinglish instructions by any chance? :D It wouldn't be the first time that translations left a gap between the promise and the reality.

Again, DPL/DPLII processing costs money for the decoding chips and the licensing. It's money that they won't spend. The solution is a cheap all-channel-stereo chip. It's nowhere near as good, but with PC speakers who can tell the difference?

You're right, it isn't surprising given what they would have to pay Dolby. I was just wondering how can 5.1 be received via SPDIF. Without compression it isn't possible.

Only PCM is mentioned, and that will just be stereo. I wasn't sure how they were achieving it, if they weren't using Dolby or DTS. You've explained it though, cheap Chinese chips and algorithms.

And you're certainly right again: Who will notice with cheap speakers. ;)

Maybe they should just stick to making speakers with analogue input only. :p
