I have the Dell dock and yes it works with steve's rom, 1.6.1, the sound works on it too, but you have to go into the dock settings and mess with it. other than that everything is perfect
sorry i should have explained better, when you place the streak on the dock the clock app immediately opens, if you hit menu it will give you the dock settings, enable speaker out without prompt, then test the sound by hitting the music icon from the clock home screen. hope that works for you
