the kernel cpu usgae comes from bcmwl5.sys (driver for your Broadcom 802.11ac Network Adapter). You use driver version 6.30.95.48, look if there is an update.
You also have DPC spikes which can cause audio drops. The USB 3.0 driver causes it:
Total = 2129 for module USBXHCI.SYS
Elapsed Time, > 1024 usecs AND <= 2048 usecs, 3, or 0.14%
Elapsed Time, > 2048 usecs AND <= 4096 usecs, 1, or 0.05%
Total, 2129
which devices do you connect to USb3.0 ports?
