Well, couple of those USB-Audio dongles from ebay are ordered ...
So, after looking into output waveforms, I will know more.
However, it seems that the dissipation of the proposed current driver design (car radio amplifier) will be definitely too high (resulting in high current consumption), especially for low-resistance motors, so chopper should be used instead (for example, NJM3771, this chip is capable of handling 700mA per coil, enough for high-torque motors). Of course, the proposed driver circuit must be modified accordingly.
