Math of Failure:

Test Setup:

Physical Modification: Applying small VRM heatsinks and thermal pads to the internal PCBA has been shown to drop operating temperatures from to roughly cx31993 datasheet fix hot

The Fix: Go into your Sound Settings and drop the output to 24-bit/48kHz. You’ll save battery, the chip will run cool, and your ears won't notice the difference. #Audiophile #CX31993 #DAC #TechTips #DIYAudio Audio Expansion Card - CX31993 Datasheet Here is the relevant technical post content usually

Step 4: Thermal pad continuity
Check continuity between the chip's thermal pad (exposed copper underneath) and main ground. If open → missing thermal vias. If open → missing thermal vias

If you are driving 16-ohm IEMs at high volume (30mW output), the chip might draw 90mW from USB. The 30mW difference is heat. But the "fix hot" issue arises when idle current jumps to 300mW due to a design flaw—leading to 200mW of waste heat inside a tiny 5g metal dongle.
