I recently bought an iRig HD2 hopeing for a silent practice solution.I have ToneX on my iPhone, and a set of in-ear monitors, and have been able to get some great sounds without disturbing the wife. But, if I try to play along with music on my iPhone (Spotify for example), the music is WAY too loud. The volume control on the iPhone does nothing, and I haven't found any other way to balance my guitar (in ToneX) and the song I want to play along with.
Any suggestions would be appreicated.
