I have been having issues with audio fluctuations on my PC (Windows 10). They are spontaneous, sometimes worse than other times. Last night it was unbearable. An example of the sound fluctuations would be placing a pillow firmly over the speaker, then removing it. Sometimes its only half a second, sometimes it stays that way for a few minutes. I thought it had to do with realtek drivers/enhancements/driver updates and i have played with them in every way i can imagine to no success. I realized over AUX another speaker is fine. My usb headphones and AUX headphones are all fine. So plugging my phone into my Bose PC speakers (the ones i'm having issues with) the audio did the same thing, although at the time of typing this it appears ok, it did happen. I had tried swapping the AUX cable but that doesn't appear to be the issue. Any idea if its maybe time for new speakers or if anyone has had this issue in the past and can give me somewhere to start. Also, note, there is no noticeable sound degradation from the speakers. They sound great. These are Bose Companion 2 speakers and have served me well for about 3-4 years now. Thanks!
