Hi Forum, I'm running a test setup, feeding µMPX from Windows ST 9.82 to a RPi Decoder over a VPN connection. The decoder sounds fine but shows constant 2021-10-25 13:26:54.643 warning: Pilot phase shift detected (0.132259). 2021-10-25 13:26:54.665 warning: Pilot phase shift detected (0.235963). 2021-10-25 13:26:54.673 warning: Pilot phase shift detected (0.178364). 2021-10-25 13:26:54.717 warning: Pilot phase shift detected (0.115455). 2021-10-25 13:26:54.730 warning: Pilot phase shift detected (-0.17188). ... messages. What can I do to fix this? |

Are you using the built-in stereo/rds generator in Stereo Tool, or are you feeding it from an external RDS encoder? |

It's the internal generator. ST itself is driven by a PCI sound card using ASIO in / out. |

Ah, and no RDS enabled yet. And I noticed that µMPX decoder refused to decode anything as long as the stereo encoder was switched off. It was off as the current setup uses the transmitters inbuilt stereo coder. Of course that all shall change when testing is done. |

This seems to be somehow related to the number of CPU cores in use. I'm searching for the cause now, will release a new version asap. |
