Hi All
I have a PS3 + LG LH4000 LCD TV both with Optical Out, what system do I need to pump out the sound using Optical?
I have a 2.1 speaker system with standard audio jack but seems to only come out one speaker quite from the TV when plugged in.
Any help would be good
You need an amp or AV amp with at least two optical (TOSLINK) inputs, although you'd get a more varied selection of audio formats from the PS3 if you used the HDMI output rather than the optical out. The PS3 has onboard HD audio decoding abilities, but can only output the HD audio as LPCM via its HDMI interface. Regular stereo amps do not come with HDMI interfaces so if you wanted to take advantage of the PS3s HD audio abilities, you'd need an AV amplifier with an HDMI repeater interface. The repeater interface is nescessary rather than a HDMI switch interface.
You could also purchase another all in one HTIB system, but one with both optical and HDMI inputs.
You can theoretically output up to 7.1 channels of audio from the PS3 to an AV amplifier, but you'd also need the additional speakers that would attach to the AV amp.
The TV only output 2 channel stereo.
Do you have a budget?
I've no idea why your existing set up is playing up and can only suggest you try different RCA leads and also check the speaker connections to the main unit.
