To view from my PC movies on TV and to duplicate the audio signal (output 1 PC speakers, 1 output stereo) I've tried several different audio distributor and couplings. Either I had only sound on a device or on a speaker, never on both terminals and in stereo. The HAMA Adapter is not exactly a cheap part, but is still working properly. The sound arrives at two speakers in stereo and good quality. For me, the purchase was worthwhile and I would recommend the adapter ..
