Can you make sure the version number of GVDSDK matches to the GvrAudioSDK in Podfile.lock?

This happens when there is a version mismatch.

[naoyax628X]

It worked fine if you match the version of GVSDK with the version of GvrAudioSDK.
Thank you very much.

I also encountered this problem, and specified the corresponding version, it's ok.

target 'TreasureHunt' do
  pod 'GVRKit', '~>1.140.0'
  pod 'GVRAudioSDK', '~>1.140.0'
end

and now google vr version info:

ft$ pod trunk info GVRAudioSDK
