The Bose V18 media center has the VS2 hook up. Using the HDMI on my new Roku 4, I have video, how would I hookup for audio. Someone told me that I need an optical digital to analog converter...is anyone familiar with this setup?
You would want to look into getting a Optical to Analog converter to enable this to work with your Bose system. Depending on what the Roku 4 provides for you audio out as for either 5.1 or stereo, you will need to make sure the converter supports converting an Optical 5.1 sound to Analog. Not all converters have that ability.
