Since upgrading my HTC One X to Cyanogenmod 10 (android 4.1.2), the app works perfectly and I never get any force closes, however, I can't use any of the built in audio enhancement features which is seriously making me consider going back to winamp, and I don't want to do that. I'm a paid customer of both apps by the way.
I get this error (screenshot: http://www.imgur.com/IlQ7n.png) that my device is "unable to initialize AudioFxs!"
I agree with Daniel Shafer (http://support.xiialive.com/topic/126186-new-xiaa-version-conflicting-with-eq-apps/) it would be great if you could allow other equalizer apps on the system to be used because Cyanogenmod comes with a fantastic EQ/custom sound tool called DSPManager - it's only available with this ROM and you can't get it in the playstore.
Here is a tutorial on how to install it on any other ROM if you'd like to do that for testing purposes:
I have 3 phones with this ROM installed, all running xillialive and none of them can use the equalizer (Samsung Galaxy S (i9000), Samsung Galaxy S II (i9100), HTC One X international GSM version)
Perhaps this discussion on a similar error might be able to help you?
