Sorry, have fogot to mention I have checked both hw:0,0 and hw:0,1 devices with the same result (using non-inverting external DAC at last case). Andrew ---------- Forwarded Message ---------- Jaroslav, Have tried the script. With given sample a speaker cone moves from a listener rather toward one. As 0x12345600 hasn't 0x80000000 bit set, I suggest a cone must move toward a listener. Well, to avoid any mysticism I simply measured DAC output with multimeter :-) The output is negative, of course.
