Loud hum when Bose speakers connected

[Franksie21]

When I plug my Bose Companion 20 speakers into my HP Pavillion all in one computer, I get a very loud and uncomfortable buzz with limited audio sound.  If I plug them into any other device, the sound is perfect.  Can anyone help me?

Hello
it is mentioned "all in one" nothing else, so we do not know which computer is
However, do you have a speaker output, or just a headphone output?
If it's a headphone output, the problem may be there, so I don't know if a solution is possible!

if updating the driver does not change anything, I may have no solution

Thank you for trying.  I have reinstalled the audio drivers but nothing has changed.  it is impossible to listen using my speakers

sorry
I have a desktop computer with 2.1 speakers, the sound is excellent, only it is not on the headphone output ..
I am afraid that the output, or connector is not suitable ..
although sometimes it works!
there I can not tell you, if this is the cause, or if it is the output that has a problem
can you try it out with a simple compatible headset?

Thank you once again.  I could use headphones but as I have these 2 Bose speakers, I was hoping to enjoy their sound quality. I guess I’ll have to give up!
