Crosstalk on Rear Outputs of SBlive 5.1 Card?

dawkorn · Sep 15, 2003, 12:05 AM

Ive recently discovered this when I heard some distortion coming from a channel at low volume thru headphones..........................I have been using the Rear outputs as my primary output channels -

SBlive 5.1 card oem

Go into dsp, create only fxbus and epilog
swap front and rear is checked (default)

connect fxbus0 to epilog/analog front left (swapped)

Right headphone has crosstalk and distortion coming out, at a lower level than the left channel, but nonetheless, its there

disconnect fxbus0 and

Connect fxbus1 to analog front right swapped
now left channel has the crosstalk, without distortion

Ok

Un-toggle "swap front and rear" and switch plug on sb live card to the front outputs (ac97)

Do the previous steps

No crosstalk on either channel using the front outputs

Any Ideas?

Thanks,

Dawkorn

try to reset ac97 settings
I currently have no ideas about any reasons of such behaviour...
