PowerConf Pumping Effect with Volume

Using the Anker PowerConf speaker I notice there is a pumping effect on the audio that is sent. It seems like a compression algorithm gone rogue. The moment I start a word it seems to think “too loud” and lowers the level, but then it seems to thing “too soft” and puts the level up again.

I have tried switching back and forth between single and multi-user mode, but both show the same behavior, although it seems more pronounced in multi-user mode.

Has anybody seen this and knows how to sort it out?

You can hear examples here:

@h.ferrazleite Do you get the same behaviour on more than one Windows device? Also is this via USB 2/3 or BT?
