My squeezebox touch should be outputting 44.1khz 16bit, but the OSD on the XMC shows 24bit. Is this a known issue? Is it possible the squeezebox is outputting at 24bit?

It^s the SBT outputting 24 bit. IIRC, LMS was modified to always output 24 bit a while back.

We don't currently have any reliable way to know how many bits are coming in on the S/PDIF inputs so we display 24, the maximum capability of the interface. With HDMI we have access to reasonably reliable information so we can display the actual bits. For analog its simple since we know that our converters are 24-bit.

When I am using Runeaudio or Volumio as the music server and delivering the signal through the USB input all the 44.1/16 content displayed as 44.1/ 24. Is it possible that the XMC-1 applying some kind of conversion to all the 44.1/16 content delivered through the USB interface? |

I have DTS CDs ripped to FLAC and if LMS was changing the stream, they wouldn't play, which they do. I think it would, if the extra 8 bits are not used for any data (i,e, just null). EDIT: To be more precise, it depends.  Can't find any references for the LMS 16->24 any more... |

I couldn't when I looked either. I think it's bogus info. |

I ran across this same issue last night (configuring a Linux music streamer, playing 44.1/16 content, but XMC-1 OSD insisting it was receiving 44.1/24). I'm pretty certain now the XMC-1 is receiving 44.1/16, the 24-bit in the OSD is just a bug (as raydyo points out earlier). I verified both from ALSA's asound settings (which confirm 16-bit output over asynchronous USB), and testing with an Airport Express, which I know has 44.1/16 output over toslink, and the XMC-1 shows both as 24-bit, so I'm pretty sure it's just a bug on the XMC-1 side.
