On a PC, I would say the most likely reason is because your sound is set to a different output. For Windows, press the Windows button on your keyboard and search for "sound settings". The sound settings screen let's you select an output device. It is very common on PCs for an HDMI output to be present, or if you have a set of USB headphones, etc. I have like 3 different outputs on one of my PCs, and sometimes it gets switched off the speakers.
Sorry, there was a problem. Please try again later.If you are getting noise when connect then it could be there is something wrong with the plug for the Bose or there is a short in the plug you are using on your device.
Sorry, there was a problem. Please try again later.Simplest thing to do is first be sure all the volume controls are up and that none are muted. Then confirm that the software for the speaker is installed and that the speaker is being used as the main output device for sound. If neither of these are the issue, then secondary idea is to put another set of speakers connected to the output of the jack to test for some reason the speakers are defective. Sometimes it can be the output jack in the computer that is bad and might need replacing, if that is possible. With some computers, the output/speaker jacks are considered proprietory and cannot be changed, they are soldered into the motherboard. So if that is the case the only other option would be to add a sound board to the computer if possible.
