I had similar issues, however patching the file as shown above caused no audio output at all on the SPDIF unless it was in AC3 passthrough mode.
Then it must be a usage error. In the ALSA system, the same stream is used regardless of audio or non-audio data.
It might be that you set non-audio bit permanently. Verify with iecset program in alsa-utils package.
