Yes. >If I read it correctly, the DAC has to be put in a special mode and then >firmware audio file is "played". >It's possible the metadata in the WAV header is required by the DAC. Yes, I think so. I do not have to enter a special mode for the update, just playing the firmware file is starting the update process. After the update the DAC is rebooting automaticaly and the new firmware is running. >Have you tested with LMS with MSB bit perfect test files ? Yes. * With my old 1.8 squeezelite version I can play all files (16 and 24 bit) bit files, but the DAC does not show the bitrate. So I think the DAC does not recognize them as bit perfect. * With the renderer in the DAC, which is connected via the upnp bridge, I can only play the 16 bit files but AFAIR also the DAC does not recognize them as bit perfect. * With my Lumin player and the regarding Lumin app every thing is fine. The DAC recognizes the testfiles and also the firmware update is working. So without LMS and with the Lumin player connected via usb to the DAC every thing is fine for the MSB, but when playing files via LMS, either with the PI connected via usb or via the renderer connected via the UPNP bridge, the DAC does not get enough information to ahndle the played files as bit perfect. The systems do behave differnt and the question is why.
