I received the MAX instead of the PRO.

I find it's very hot.

It is normal. Measured it with pyrometer. It is not hot. It is warm. 40°C on average. If it warm - it working)

One problem: when you connect it to a PC USB port and near is USB Wi Fi... Sound stops for half a second or a second. And then play normally. If I download a torrent, it happens very often. Every 10-20 seconds or less...

This looks more like a PC issue. Have you tried with another dongle or USB audio device?

Hator 7:1 sound card that's really a chip long dongle with buttons. Work without problems.

Haven't another dongle yet. Wait for e1da 9039s to test it.

Don't think that it is problem of this model. More like a real PC problem. It is China's motherboard for the x99 platform with Intel E5 2699v3 server processor)

On the LG V50, use Wi Fi and jm20max, no problem.
