Having problem outputting audio from Sony 95L to RS151

Would like to use tv audio with my two channel system. Using HDMI from Sony earc to RS151. The connection only works sporadically, what am I doing wrong?

We apologize for the delayed response.
Please help us confirm a few things:

  1. Is your RS151 connected via an HDMI cable from the eARC IN port on the RS151 to the eARC OUT port on your Sony 95L TV?
  2. In your RS151 input/output settings, is the input set to eARC IN?
  3. Please check whether PCM output is enabled in the settings of your Sony 95L TV.
