CEC version set to 1.3a still reported as 1.4 #614

Closed ballle98 closed 1 year ago

ballle98 commented 1 year ago

I'm working on a project here to bridge CEC to LIRC to control the volume on my ancient Yamaha receiver. https://github.com/ballle98/cec-lirc

I'm setting the version to 1.3a to try and avoid issues around ARC (which was added in 1.4) but it's returning 1.4 to my TV

CECConfig.clientVersion = LIBCEC_VERSION_TO_UINT(4, 0, 0); // 1.3a

Figured it out 

  CECConfig.clientVersion = LIBCEC_VERSION_CURRENT;
  CECConfig.cecVersion = CEC_VERSION_1_3A;
