Can anyone help. I have the new Arcam Solo Music and stream to it via a chromecast audio. I bought this because I experienced dropouts using the Bluetooth of the Arcam. I decided to buy a toslink cable for the chromecst as a kind of upgrade to 3.5mm supplied with the chromecast. However, although it works fine with the supplied cable, when I plug in the toslink to the optical point on the Arcam it doesn't work and I subsequently don't have any sound. Any ideas as to why? I emailed Arcam, but they havent bothered to answer.
