Hi,

After having used my USB remote for 2 years, I heard a weird noise coming out of the device several times today. The noise is very similar to the succion sound one would make when trying to sip the last drops of a drink through a straw. It really made me jump the first time, because I wouldn't expect anything like that would be possible since I can't imagine there are any moving parts (no fan or anything) in this unit. But the noise has happened several times ever since and it's clearly coming from the inside of the box.

The remote is working perfectly fine so far. Should I be worried?

PS: I haven't been drinking or doing drugs lately.
