I have hooked up a headset to my Nanopi Neo Air, but the microphone quality is severely impacted by electrical hum. I have tested it and determined it is due to a power supply with no ground, i.e. the typical 5VDC 2A with a two-prong Europlug. Using one of those small power supplies in metal cabinets, with a ground wire, and the hum is gone.
The latter is not really an option, so what do people do instead? I know this is hardly opensuse specific, are there any better lists out there? (for this type of general-use question). -- Per Jessen, Zürich (6.9°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland.
