Yo! Hey peps, Im using realtek on a 7.1 onboard with ALC888 codec (asrock esata2 mobo). Im running my Mordaunt Short Avant 309i into the centre/subwoofer port and my pc speakers are in "front spk out". Now im having to run it on 6CH to get tha sub on (can't find a 2.1 patch) so im loosing sound to the rear and side but thats not my issue. Realtek is running the centre through the sub? Its treating them as the same thing, the volume control for either will kill the sound if bottomed out neither appears dominant? Ive looked into other 7.1 and 5.1 sound cards all seem to use this centre/sub port.......but will it hurt it? Its set to only re-produce sound below 90hz so im thinking if guitar or vocal comes through (obv' it does) only playing low levels it should be fine but id be lying if i said i wasnt quite worried im sure ive heard the odd faint 'spitter' hope you can help thanx!
