More detailed description:
The TV was connected with this cable to an AV receiver. About the ARC function of the HDMI cable to the TV audio to the AV receiver was passed, which then spent it through the speakers connected to it. This worked in principle, however, put the sound when adjusting the volume always for about 0.5 to 1 second. It did not matter if the volume control on the remote control of the TV, the AV receiver or on the mechanical rotary switch was made.
Use of another cable, the problem did not occur.
Furthermore: The cable is by his shield quite stiff. The connectors are too close to the edge of the screen, it may be that the cable behind it is revealed. One should check if this is relevant for existing equipment.
