Hi
Sometime during Dec2017 and Mar2018 something changed in the RaspberryPi/Max2play/Squeezebox ecosystem. My 96/24 Flac music files that previously played on my RPi3 SqueezeboxServer now no longer play. The ONLY files that are affected are those that were encoded using „Lavf57.34.103“ (eg. as sometimes provided by HDTracks.com). That encoding might be some sort of ffmpeg-based version of the flac standard, but I do not really understand the details.

All my other flac files, encoded with FLAC1.2.1, 1.3.0, 1.3.1 etc, still play perfectly.
The change & problem may have been caused by recent updates in Max2play, or in Raspian, or in squeezeboxserver7.9.1. I thought I’d start my detective work by asking the Max2play community: Has anyone encountered similar difficulty?

Thanks for your help

Hi Manawatu,

Which version of Max2Play (Stretch or Jessie) are you using? Also, what output device do you use?

Do you use a sound card, and if so, did do you have hw volume control enabled? If not, please do so, here’s the guide.

You can also check the advanced settings of the LMS for individual encodes and formats and how they are handled.

Hi
There is no sound card on my RPi3, just ethernet out to the router, the NAS and the Transporter which handles streaming and DAC.
The LMS codec settings for FLAC filetype are all at default: AIFF=flac, FLAC=native, MP3=flac/lame, PCM=flac.
Recall that the flac encoder used by HDTracks was “Lavf57.34.103”. If I re-encode those files (hires flac to hires flac) with dbPoweramp (which is currently using flac encoder version 1.3.1), then the files will play.

Note that the original Lavf57.34.103 files can be played on Win7 software players like Foobar2000 and MPC-HC, but I don’t know if they are „native“ or are transcoding in the background.
