[quote user="Tony Philipsson"]Only thing missing is 0.1uF cap between Vcc and GND as close as possible to Vcc pin.[/quote] 0.1uF is good for decoupling. TV speaker have low impedance, thus trying to drive it, msp430 can get brown-out and reset or just hung. To handle power consumption spikes, additional "storage" capacitor needed, like 22uF-220uF or so. [quote user="Tony Philipsson"]Could try to put a 22uF-220uF cap in series on speaker output as you need to make the signal float.[/quote] 22uF-220uF could be too much. I would try series 100ohm resistor + 1uF first, see how it works, then increase capacitor up-to 22uF at max, obviously leaving 100ohm resistor.
