Hello,
I'm using Fedora 24 x64 and I encountered some problems after updating from kernel 4.7 to 4.8 (now 4.8.8)
After update, I have no sound and youtube playback freezes. I manage to indentify the problem and seems to be related with my sound card (Creative X-FI).
If I use the onboard card sound and flash playback works, but it I use the Creative card, there is no sound in audio/video files and flash playback freezes.
My output of alsa-info script is here: http://www.alsa-project.org/db/?f=f6b183e3a2583c0c051f38c7f6e4f799fd1cc85c

I'm not good at doing alsa configs, I need some help in identifying if there is a configuration issue or some defaults in the 4.8 kernel make my sound card to malfunction.

Thanks,
Bogdan
