I fixed this problem on a client computer by upgrading the Conexant Smart Audio HD driver to the specific windows 8.1 version. This also corrects the Windows 8.1 Dolby driver issue. Search for the driver on your computer manufacturer's webside. In this instance it was for a lenovo u310. Good luck, Spotifiers!
I had the same problem!! Every single thing failed and even installing and reinstalling twice failed. I went into all the sound stuff and was about to go to lenovo's website (using lenovo yoga 13) and then i tried the Ctrl+Alt+Home and then it worked!! idk what the hell that command does but apparently it fixed it.. idk how at all and i don't understand it but i love it.
thank you so much!!!! now to see if this fixes the other sound problems on windows 8.1 -__-
It happens anytime I'm using Spotify. If I'm using Soundrop or Radio, it still will stop after 2-3 hours. I tried downgrading to regular Windows 8, but that doesn't look like that'll work. I also have Unlimited. Did Spotify manage to install a time limit?
