I have a PC that I built some years back. Like a champ, it ran Windows 7, 8, and 8.1. Then I upgraded to Windows 10.
Immediately, I began experiencing ripped sound playback, regardless of sound source: VLC, Windows Media Player, Flash in Firefox, etc. behave identically: every few seconds there's either a "rip" or a momentary dropout of sound. Sometimes, bizarrely, the music actually slows down by a few BPM for a few seconds.
I noticed that this problem occurs only when the PC is associated with my wireless network (which uses a rock-solid router and I haven't touched in over a year). As soon as I disconnect from the network, sound works perfectly.
Figuring that the NIC is old and probably isn't compatible with Windows 10, I switched to a modern NIC (ASUS PCE-N15), yet the problem remains unabated.
Windows 10 does not find any improved drivers for any of my hardware. I set the Wireless Adapter's Power Options for "Maximum Performance", and changed PCI Express -> Link State Power Management to "Off". No improvement.
What else can I try? I'd hate to downgrade back to Windows 8.1.
