hi, i can't connect the Marshall box to Bloototh and the beamer. it is recognised but doesn't connect in the end. it works with the Boombox though.
what can i do? Marshall the sound is much better.

What is your playback device? Have you already looked for a setting to compensate? Unfortunately, it is often difficult to realise synchronous playback via Bluetooth.

Hello, unfortunately I cannot answer this question. I have connected the beamer and also the TV to a matrix box. I assume that Hdmi-Arc does not work. Otherwise, ask Epson directly.

Google Chromecast mit TV US-Version (Google Assistant)

Hi. HDMI ARC and then a Smart TV dongle such as Apple TV or Google Chromecast directly on the projector unfortunately does not work. The HDMI connections do not support audio return in general. The beamer is Bluetooth-enabled but I have not managed to connect either headphones or the AV receiver, which is unfortunately bogged down. I now just run an HDMI from the AV receiver to the beamer and that's it. If it has to be a wireless version, I could recommend the new Google TV as a dongle. This could be paired with the AV receiver via Bluetooth, if the AV receiver or the soundbar support this. If you have any questions, please contact me...
