I had some external speakers that stopped working so that sound came through the comp0uter's internal speakers. The speakers were old so I bought some new ones but they also do not work. The new speakers come with two cables, one with a jack plug and the other with a USB plug. I have tried plugging the jack into all 3 sockets on the back of the computer and in the two, red and green, at the front - no joy. I have tried using the USB connector with the same results.
I am using Windows 7 on a Lenvo computer.
I have an idea that, in the past, I had to change a setting but searching through "Devices and Printers" does not help.
"Sound" lists three devices: Digital Audio (HDMI) Not plugged in; Speakers Default device with a green tick ; another Speakers not plugged in. Right click on this last device gives me Properties and at the bottom Device Usage which is set to Use this device (enable) but seems to have no effect.
Can anyone help me please?
