IM NOT GOOD AT English
Im using my PC as a source for playing music.
My gears: 2 Speakers, 2 mini rear speakers, 1 mini subwoofer, 1 amp for power the speakers. All can be plugged into the speaker amp.
My setup: Source (PC) > Schiit modi multibit (usb) > (2 RCA) to speaker amp > Speaker. My front speaker work, but my rears doesn't (because its driver not bumping) im not sure if sub work because i cant see the driver.

I Tried to setup my schiit modi but i dont have option for 5.1 or 7.1.
What's wrong with my setup guys?
Thanks.

The Schiit is an good 2 channel DAC for the price but doesn't do 5,1.
Not knowing what speakers you have I will guess that there is no surround processing built in so to get surround sound you would need to connect them directly to the 5.1 audio outputs on your PC and let it do that. If your PC doesn't have 5.1 analog audio outputs you could buy a USB 5.1 processor that would provide those.
You could switch the 2.1 speakers between the DAC and 5.1 outputs. Or get good powered speakers for the DAC and leave the 5.1 connected to the PC.
If there is a separate subwoofer input then the sub is probably not working.

Thank you for your inputs.
I wonder if an usb 5.1 only make PC have 5.1 output without decoding digital signals or it can do both like a standalone DAC decoded digital signal to analog.
Any suggest for usb 5.1, a soundcard maybe?
