I'm not 100% sure, but I thought it was running in stereo mode when the right red LED was lit.
According to Delock support, the unit always runs in stereo mode first after it is switched on. That's how I remember it. :)
The Sonos Beam has only one HDMI port and can therefore be connected to an HDMI ARC port of the TV. You don't need any other adapters.
If the TV does not have HDMI ARC, you need a device that converts optical audio to HDMI, which is exactly the opposite of what this device offers. Sonos lists https://www.sonos.com/en/shop/optical-audio-adapter.html on their site and mentions it in the manual of the Beam: https://www.sonos.com/support/en-us/sonos-user-guide/index.html#t=sonos-user-guide%2Fbeam%2Fbeam.htm%23TOC_Connector_panel5bc-2&rhtocid=_0_2_9_1
Win-10 / Audio driver problem. I need to turn on PC (Samsung Galaxy TabPro S), then while Samsung logo on display give power to HDMI Audio Extractor.
Test: Open Sound Settings, Manage Audio Devices, select each device and Test and see which device is getting sound.
For me, it is device "EP-HDMI-RX".
If you're aiming for 4K, you'll probably have problems... 1080P works, I had also set it up that way. But since everything is 4K, I use the sound via HDMI and then from the optical output on the TV to the amplifier...
Sorry, don't understand the target setup. The audio sound of the TV is currently output via the ARC, correct?
Why then send the sound additionally to the Sonos Connect or should the Arc be replaced?
What is the connection to the Delock HDMI Audio Extractor?
the hdmi output signal remains unchanged.
at the same time you have a s/pdif signal with 5.1/7.1 surround on the coax or toslink output if the input is compressed (e.g. dolby digital or dts).
with a multichannel pcm input signal, a stereo signal is output on coax and toslink and the multichannel pcm remains in the hdmi output (however, this is due to the bandwidth limitation of s/pdif).
If you have a separate TV receiver, this is possible. You go from the receiver to the extractor via HDMI and from the extractor with the jack to the boxes and again via HDMI to the TV.
I have a similar setup and can imagine that it works. In my case, I connected the Apple TV 4 to the Delock (since the Apple TV 4 only has an HDMI output and no longer has a Toslink output). I connected the Toslink output of the Delock to my BOSE system. In their case, the Delock would be connected to the Denon AVR (and not to the Apple TV like mine). The Delock works very well in my case. However, it does not automatically recognise whether the signal is Dolby or stereo because of the Apple TV signal. I have to switch between Dolby and Stereo in the Apple TV.
I have a similar setup with a Google Chromecast, a beamer and a 5.1 home cinema system, among others. It works there, but if the devices have been in standby for a long time, the power has to be disconnected from the Delock and then reconnected so that I get a picture on the beamer. I can't say for sure whether this is because of the Delock, because I also have an HDMI switch in between.
I have a lg bh9540 and have a swisscom box connected to it with a beamer. now I would like to listen with headphones. Can I hang this device in between and connect headphones?
