Hello i have computer speaker but for some reason the computer is not detecting the speakers

It's probably not the speaker, your phone is not recognizing the device. This is the link How to troubleshoot Bluetooth Connections from Apple:

Hello,

It could be that the speaker is not connected properly or it has gone bad. It could also be an outdated sound driver. It's better than you update the sound driver before fixing the hardware part of it. You can use RadarSync to auto-detect the updates and you can use the same software to automatically update them without you downloading anything or something like that from the manufacturer's website.

Hello k andrew, hi, check to see if the computer has detected the sound card circuit, usually on the system list of hard ware devices. if not need to install sound driver. On windows 7 right click my computer . properties . device manager.

just go into sound config on your computer, select your speakers & problem solved. happened to me when i changed my service pack with vista. for some reason speakers switched to bluetooth after install. just changed them back in your sound config, problem solved..

Be sure that you have not "muted" your computer's audio-output.

Open the audio "mixer", and check that the "line-out" mix has not been pulled-down to a 'zero' level.

Try the speakers in some other (desktop or laptop) computer.

Try different speakers in your computer.

Check that you're plugging-in to the (green-coloured) "line-out" socket on your audio-adapter (not the blue-coloured "line-in" nor the pink "microphone-in" sockets).

There _are_ limits to what the "Plug-and-Play" features of Windows will detect. Generally, speakers are *NOT* listed within Device Manager.

Try switching from '5.1' to '2-channel-stereo', just to test it.

turn the power on, then unplug it to computer and touch the input, if there is no crackling sound the amplifier is defective, a technician guy like me can fix the problem

first u check sound driver are matching motherboard

Hello there!
It sound a power adapter failure,
check your speakers for power failure, or bad connections,
check also your sound card, mixer, and drivers.
perhaps if a onboard sound is disable for some reason.
check that too.
Good Luck
