I have a MAG 351 and I have audio problems in some channels, they only look but can not be heard. The other way around also happens with other channels, they are heard but not seen. The portal works well, I've tried it on other devices and the channels work well, they can be heard and seen correctly.
It is connected by cable with a speed of 90 Mb / s. The firmware version is the last one. I have made several factory resets, I can not fix the problem, I need your help.
