The user manual for the GA-78LMT-USB3 Rev 4.1 mobo states that the Realtek ALC887 codec can handle up to 7.1-channel audio, but that it has to be configured using the HD front panel audio module, and the multi-channel audio feature must be enabled through the audio driver.
I have the Logitech X-530 speaker system which requires it's three jacks (green,black & orange) to be connected to the PC to obtain surround sound, but the back panel of the PC only has one line in socket (blue), one line out (green), and a Mic (pink). By plugging the green jack into the green line out socket, I am able to get stereo sound through two of the speakers only, but I cannot figure out how to get all of the speakers working in order to receive surround sound.
So far I have plugged headphones into one of the two audio jacks on the front audio panel of the PC and this gives good sound quality. The second audio jack appears to be for SPDIF but I cannot get any sound by connecting any of the three speaker jacks into it.
Plugging the green speaker plug into the same jack as the headphones on the front audio panel also gives good quality stereo sound through two of the speakers, although the playback device display states that headphones are plugged in rather than speakers.
I have tried messing around with the driver settings in Control Panel to no avail and the only conclusion that I can come up with (which may or may not seem obvious to others) , is that the system is unable to provide surround sound using the onboard sound only and that I need to buy a soundcard.
Please can anyone confirm if this is the case ?
P.S. The same surround speaker system works fine with my other PC which has corresponding coloured sockets on it's back panel for the three speaker jacks to connect to.
