Windows 7: QSB Speakers stopped working

QSB Speakers stopped working


I have a pair of QSB speakers from SoundScience, USB powered and USB Output (no jack) which worked fine for ages on my Samsung laptop then suddenly stopped working a few months ago.
I think it must be a problem that occurred when I updated some software, though I am not sure what.
The speakers are recognised by my laptop, as they appear in the Sound Properties window when I open it. The problem comes when I try to set them as default to make them play- nothing happens, and they cannot be set to default, nor can I test them. I have tried rolling back drivers, updating drivers, both on the speakers and on my sound card, but the problem remains.
At this stage I don't have the skills/knowledge to go deeper into the workings of it and I'm stuck trying to get these speakers to respond via the standard sound properties interface. I thought for a long time that it was the Samsung software that comes installed on the laptop, that was conflicting/causing the speakers to not work, but I have tried un-installing that to no avail.

I am running Windows 7 on a Samsung NP300ESA laptop, with a Realtek HD Audio sound card.
Please let me know if you need any more information about my system or the problem.

I appreciate any help you can give me on this

Many thanks

Sounds like there may be an error with the USB connection. Go to the Device Manager and check the Sounds section to see if anything is listed for the USB speakers (and if there is any error code). Also, check the USB section to see if there are any unknown devices listed.

Hi Fireberd,

Thanks for your reply. The speakers show up in Device manager as "QSB," no error code. There are no unknown devices in the USB section.. I have finally managed to test them on another computer (had to get my old laptop running again to do so) and they appear to work fine on that.. I looked into the speaker properties and it all appears as it should, they are enabled, and Windows claims that the drivers are up to date. I tested all of my USB ports with a memory stick and had no problems with any of them. I have also tried the speakers with 2 other USB cables that I know to be working, but the problem stays the same.

Plug them back into the PC, then go to the Device Manager, RIGHT click on the entry for the speakers to highlight them and then LEFT click "Uninstall". DO NOT uninstall any drivers. Then physically disconnect the speakers from the PC. Restart the PC and after Windows finishes initializing connect the speakers and Windows should detect them and install them. This fixes a lot of corruption problems and if you are lucky will fix this problem.
