I have a Sir-Alp1 tuner with the MJS USB interface. It's connected via optical cable to my Soudblaster Z digital input. I'm running Centrafuse 4.x, Win8 32bit on an AMD E series system.
The sound quality from the Sirius tuner seems to be very bass heavy and limited on the upper end. I can't seem to equalize it like I can with all other audio on my system. I've tried the equalizer provided with the soundcard and with Centrafuse, and neither seems to affect the line-in connection. Right now my .mp3 files sound great, but my Sirius audio is very bass heavy and annoying.
Anyone know how to fix this?
