Yeah, but if it suddenly stops in the middle of playback then that'll tend to register with users and if you keep it powered off at all other times.
Hm, the goal is to fix the issue without user interaction. The app will keep the device open and will play back without noticing the problem.
Well, the user is going to hear a horrific glitch anyway...
Well, the problem we are facing here is not really showing up during normal operation. The amplifier is resetting only if there's a strong electrostatic discharge on the front panel of the device. This is most likely only going to occur during an EMC test. To pass the EMC test a short dropout is acceptable as long as the device continues normal operation afterwards.
Of course there's a small likelihood that such an electrostatic discharge will happen in real life, but we have never seen this happening so far and if it will happen the user will most likely prefer a short dropout over complete failure.
