These are analog speakers and do not need a driver. First, make sure they're plugged into the speaker/headphone jack and not the microphone jack. Second, make sure the computer's sound output is enabled and set the headphone/speaker jack. Third, verify that the sound output is working by plugging in a headphone set or a different pair of speakers. If the computer sound checks out, the speaker cable is bad or the power supply is not working.
First of all, nothing wrong with the fuse. A fuse is nothing but a short piece of wire with a resistance value. If the unit turns on, fuse is fine. The fact that the headphones you plugged in are working tells you that the music is finding it's way up to that point. You must realize that the speakers themselves have additional circuitry that the headphones don't use. If you could obtain a diagram for the circuitry you might find that a capacitor or a diode or a transistor got "zapped" when the high voltage was applied.
If you have this diagram and you don't know what component is defective, can you post that diagram and I would be glad to help!
Based on the information you have provided, it seems that the issue might be with the Audio Output Jack.
Usually some Computers have an additional Audio Jack on the CPU.
If you have such an option you can try connecting the Speakers and Headphone to that Audio Port and check.
If you do not have an additional Audio port, then it is confirmed that the issue is with Audio Output Port.
It is recommended to replace the Sound Card. You can also check with your favorite Computer Retailer, if only the Audio Output Port can be replaced.
Please let me know if you have further questions or need any assistance.
From everything I've read and tried over the years it all points to the same thing. Because there is such a big imedence mismatch between standard headphones and laptop output jacks, that they never seem to quite work. I have seen a couple machines that the sound works fine but for the most part the sound is either dull or tiney.
Same here. I tried many things but cannot ring it back to headset mode. I continuously see the headphone icon shown in the phone, so it seems that the phone thinks that it is still connected to earphones. Sometimes, it works fine, but mostly it does not. If I connect the phone on bluetooth earphones, it works fine. Any help will be appreciated.
