Interested HDMI Switch with Audio Extractor feature

The Ligawo ® HDMI Switch 4x1 - Premium 1080p 3D ARC HEC - Toslink / SPDIF Audio delivers as expected a good picture, the switching via Switcher button or remote control works reliably, with inactive ports will be skipped. With a USB A-> hollow plug cable (eg Delock 82197), the switch via a USB port (eg. As the monitor, TV, projector) are supplied with power. Has been connected previously a Fujitsu-Siemens notebook, a Mini-ITX computer via VGA> HDMI adapter, a RaspberryPi, a Google Nexus 4, an HP monitor and a Logitech surround sound system. Both the laptop and RaspberryPi LPCM 2.0, AC3 and DTS were passed through to the Logitech surround system via Toslink.

A star deduction:

1. Is there that in the manual does not appear that in addition to the SPDIF function the ARC function must be enabled to use the TosLink connection. The # Converter gates # -Support did not know this peculiarity.
2. If the final state (z. B. ARC actively) through a power saved. Each time has to be thought of the ARC function.
3. The lateral outgoing rigid HDMI, Toslink and network cables need through their large bending radii much space.

The high-speed Ethernet function (HEC) was not tested due to lack of equipment.
