A couple years ago, I bought an A&K PEE51 USB-C Dual DAC for my daily on-the-go listening. At the start of this year, I started noticing that the audio would randomly cut out when connected to my Samsung Note 20. It would be fine for multiple hours, cut out, and then need to be unplugged/replugged to work only for a few minutes before the audio would cut again. I haven’t noticed it happen with my MacBook Pro, the only other USB-C audio device I own.

There is no warning when it will happen. My thought is maybe it overheats and shuts down to limit damage? It does get quite warm when running, but from day one it always ran a bit warm (some reviews noting such). Nowhere can I find anybody with the same issue. Has anybody used this DAC before and/or come across something similar with USB-C DAC dongles?

I got an ifi go blu to use instead when this issue started, but the battery on it ballooned and I have to use the A&K while I wait for my replacement blu. I would love to solve this issue so I can use both DACs.
