Ok, i have 5.1 surround sound set-up in my room, the specifics are Logitech Z906. My monitor produces no sound so these will have to do. However, when i play my playstation 4 i cant get any sound, unless i re-plug everything so one wire goes from my control to my speaker, of course you can see the problem already, and if not my problem simply is "i need a speaker with Optical cable support" My mum says a simple A/V receiver would help, my dad insists i buy a new surround sound and put my current one downstairs. i have a limit of £200 to spend on either new speakers, so my question is what can i do to sort this out? would an A/V receiver sort it out? ive looked and seen that A/V recievers had stripped wires, whereas my speakers are plugged in, so what are my options?
