Is there any application I can use to equalize my entire overall output? I realize I would have to do this for both ALSA and OSS, but my onboard sound is trash and I'd like to spruce it up in the meantime before I get a new sound card. I currently have the X-Fi XtremeMusic, which doesn't work under Linux.
Edit: Just realized I posted this in the wrong section. Delete please, reposting elsewhere.
