Hey guys, I have a pretty big issue with my "acer aspire" laptop. I've been trying to connect my bluetooth earphones (treblab x100) but I couldnt get it to connect, so I restarted my laptop but told me to update, and I did. after the update, I had no sound AT ALL on my laptop, when I play the test tone it gives me the error "Failed to play test tone", so I decided to try playing my music that I already have but it wont play and it gives me this message ("Cant play. We can't get to the file for this item. If it's downloading or just finished downloading, try again soon. Otherwise, make sure another app isn't using the file and that you can access the place the file is stored."), after that I tried to play a video but it wont play. I dont know if it was caused by the bluetooth earphones or the update. ive also tried wired headphones and an external sound card. Thanks in advanced!
