My product decided to make a pop sound and start smoking yesterday, so I turned it off and let it sit for a few minutes to stop and then turned it back on and it was working fine, but it popped again today and now the headphone out doesn't work, turning of the knob interferes with the audio by pushing the drivers in and out slowly, and the line out is extremely quiet. Is there any way Massdrop would be able to help me get in contact with Aune to solve this? They haven't responded to my emails...
