Software decoding on an x86 CPU is theoretically possible but impractical: A 12-core Ryzen 9000 series achieves only 18fps at 4K while drawing 95 watts.

The device becomes hot enough to be uncomfortable to touch, then the volume drops by 50% after 30 minutes. Solution: The full mode draws 1.8A at peak. You must use a 5V/3A power supply (not a standard phone charger). Also, install the rubber feet to give the bottom ventilation. For stacked systems, a $20 laptop cooling fan placed under the Sone127 eliminates thermal throttling entirely.
