Hi,
I just purchased a set of external speakers (Sony SRS-A201) that were really inexpensive. My wife is hard of hearing and I thought this would increase the volume on my MAC laptop. I have added speakers before and had no problem. I have connected the power source with their jack into the left speaker as indicated on package and connected the jack that comes out of the right speaker to my MAC. The power light (green) indicates power is on and the only two options for the jack into my MAC are the "headset icon, or the one right next to it that has an icon that looks like speakers. I went to XM.com and found that it didn't work. Am I missing something, or should I just return them. Thank You
