SPDIF speakers?

A good choice. Has both optical and coaxial connections.

Yeh

, it arrived today all good, but the problem is that when I connect the coax cable to the soundbar no problem but it extremely loose when connected to the android box. I had a feeling it might not fit. any help guys?

The metal sleeve that surrounds the centre pin, usually is split into four sections. You should be able to push each of these towards the centre pin so that they have a tighter grip on the connector when the plug is pushed on. Try not to push them into too far, otherwise the plug won't push on at all. Maybe just one will be enough to provide better grip.

Well when I plug it into the soundbar it clicks in, but on the other end I plug it right in and nothing and it kinda bounces back outit fits but so loose. the cable looks identical on both sides. After looking on this site that has similar problem, I think I need this SPDIF-3.5mm to RCA . cos I think the 3.5mm jack will fit into the SPDIF port correct?

heres pic I uploaded(sorry bout dust lol)-

Ah, I see. I assumed your Android device had coaxial connection. 3.5mm is not very common when used for SPDIF. You could try to a 3.5mm mono to RCA adaptor. There are 3.5mm mono to RCA cables, but they look piddly and cheap. Not a good idea for coaxial use really. Better to make use of a proper coaxial cable.

Yeh, I just tried a 3.5mm earphone cable and it fits in perfectly into the SPDIF, so that confirmed lol. Ok so if I get the 3.5mm mono to RCA adaptor, but will it be suitable if I plug Coaxial cable through that adaptor?

Thanks

It should be, unless it's optical. 3.5mm connections can be used for optical. Some sound cards have dual purpose sockets, so they can either take a 3.5mm jack (line-in eg) or a mini toslink cable or adaptor. Saves having two separate connections on what may be a low profile card with limited space. You'll know if it's a SPDIF connection for mini toslink optical though, as a red light will be shining out of the connection. As you haven't mentioned that, it's safe to say it's meant for coaxial use.

Ok cheers, would these work?
So I ordered 3.5mm Mono Jack Plug to Phono RCA Socket Adaptor, fingers crossed

All good the sound is coming through

, it lets me choose between PCM and RAW? which ones better lol? is there anyway to stop the sound coming from the HDMI im viewing it on beside putting that on mute?

If you're watching something with Dolby Digital, by selecting RAW, that will need to be decoded by whatever is on the other end of the SPDIF cable; in this the sound bar. The sound bar can take DD coming in, so selecting RAW shouldn't be a problem.

For PCM (pulse code modulation), any DD audio will be decoded internally and then sent out as stereo PCM. This would need to be selected if the device connected has no DD decoding of it's own. Maybe a TV, for eg. Some don't have DD decoding, so will require a PCM signal.

As for stopping the sound coming from HDMI. Unless there is a setting in the TV options that will stop audio coming in fro HDMI, then it will need to be a setting in the Android box options.

Thanks for the clear explanation again

, appreciate the help!
