I thoroughly tested the patches when the bug happened to me before. The same kind of stuttering never happened again after the fix was released. I suppose the newer reports are not related to this bug. Please understand not all choppy audio has the same source.
You may troubleshoot over these things: 1) Turn off Wireless and Bluetooth. CSR Bluetooth adapters are more stable. Broadcom to my experience is very bad at this. Realtek wifi chips are kinda bad, too. 2) Do not use USB hub, or make sure it is sufficiently powered (>500mA per port, >2A DC adapter). 3) Make sure the playback samplerate is native of the device. Pulseaudio's SRC could introduce stuttering. If your DAC is 48K by default and you output 44.1K to Pulseaudio, it can chop things up. 4) Do not use aggressive power save options in your BIOS. 5) Try plug the DAC on USB2.0 only ports, not USB3.0 ports. Many USB3.0 ports are running on 3rd party chips.
