Go to Control Panel -> Speaker --> Speaker Setting Advance. Make sure you select 5.1 not Stereo ..... something like that

got pics of the installation? rear side

>5.1
>2 speakers

Kolos

wait wait wait

you have a mixer, 3 different brand of speakers and you want 5.1?

doesnt work that way bro, you need a 5.1 decoder, this can be a small sound card or something bigger like a home theatre system. without this decoder you can only get a simulated surround sound, through using software emulation.

also you need the format of the song/movie in 5.1 format, downloaded stuff from internet normally dont have.

The PC can't detect the 5.1CH it only avialable for stereo...I saw it but I can't select...is it bcoz I am using onbiard sound chip?

I think even on board chip also 5.1 nowadays. Maybe you try to update the sound driver on mobo.

can I request a pic of your pc back panel ports?

My mobo only LGA775 is old mobo

I check on Internet that the spec for audio is still 5.1. You should be able to find the 5.1 selection in drop down list. Why not reinstall audio driver

ICH5 built-in audio controller + AC97 Codec ALC655 (5.1 channel)

oooo I think it is not about the pc. Actually how do you connect to your audio system? Thru Yamaha emx-200? Will the Yamaha accept the S/PDIF output of your motherboard?

If it does, then still you need to go to Control Panel>Sound>Playbak Device .... blah blah blah and select 5.1 output

I think this mixer accept stereo signals only, i.e. stereo signals from several source. Anyway, the mixer is to mix sounds from multiple source. It is not meant to mix FrontLeft:FrontRight, RearLeft:RearRight and Center:Sub. Did not work like that like +3kk! said
