Yep.

You might try the 7.9.0 beta. There seems to be a plugin that just needs to be enabled.

No plug in it seems, you just need to enable DSF/DFF in the File Types tab..but at this point it only now indexes them and displays in the browser, but no playback..yet.

  Hi there.
  First time I tried DSD on LMS and squeezelite myself.
  
  I compiled the latest squeezelite-git (1.6.1) and ran it against LMS 7.9.0.
  squeezlite needs to be compiled with cflags "OPTS=-DDSD ; export OPTS"
  This way squeezelite -h will show a -D option and under Codecs -c you'll also find dsd. Premade squeezelite binaries (Rev 1.5) are also compiled with DSD support. I havn't checked them out though.
  
  DoP will be enabled with "-D" option at squeezelite startup. The server then realizes that there is a DSD capable player connected.
  7.9.0 seemed to have recognized the DSD128 files by default during the initial scan. I haven't applied any specific configurations.
  
  TestEnv:
  OPUS 3 DSD Showcase DSD128 .dsf tracks, on my TEAC UD-501 (hooked up locally to my server) feeding my Adam A5X.
  My server runs Ubuntu Server-14.04 (just released), a 3.13 kernel and LMS 7.9.0.-beta-daily from 04/22/14
  
  Result: It works. Quite nice.
  
  There seem to be different options to
  1. run DSD2PCM (converts DSD to native PCM -- server plugin?? (Haven't checked yet how this can be accomplished). This feature would be required for
  DACs without DSD support and would probably go hand in hand with a sample rate converter.
  2. DSD2DoP (puts DSD into PCM/flac framework). This mode seemed to work
  out of the box on my .dsf files.
  
  Note:
  If you run DoP, your squeezelite player SW volume control will be locked automatically at 100% (you can move the slider, but nothing is gonna happen). The lock needs to be in place to avoid data corruption of the DoP (fake PCM) stream. Keep in mind: You need to have an analog volume control in place !!! Otherwise you might blow up your speakers (and ears) .
  Very important:
  A DoP stream needs to be delivered "bit-perfect" to the DAC. If you have any resampler, digital volumecontrol, dsp, pulseaudio, asf, in the chain you have to turn that feature off.
  .
  .
  .
  LMS and DSD. Had it on my action list for a while. Now it's ticked Off.
  
  THX to those highly motivated folks who made this happen -- all free of charge.
  
  Back to the real stuff -- 44.1/16 - straight PCM . ;)
  
  Good luck. Enjoy.

    the DSD2PCM function is built into the binary for the Linux community project, but AFAIK nobody has run a build for any other platform with it included yet. I loaded the 7.9 beta for a few days and noted the new file types were enabled, but I am still trying to get squeeze lit to play again after a recent plugin update where I lost MP3 playback. I also had to go to the 32-bit binary for SL in OSX. I think Triode broke something in 1.6. Also, Triode has taken over the binary for DSDplay and will be building a plugin.

    Hey there. So far I have had no luck getting LMS to play DSD. The Sonore app to convert FLAC to FLAC for DoP does not work correctly, and I tried it in Foobar, and the DAC (yes, DSD capable) still thinks its 176.4 PCM). I have done everything correctly.
    
    I am in no hurry. I have 50 DSD files in my library, so it is not a priority, However I will be doing my own DSD recordings. Native DFF support won't be too far away.
    
    Thanks again for post about the LMS updates!

      Hi.
      
      I do not convert my dsd files at all. That's done on the fly.
      
      Cheers

Thanks. Downloading now. The death spiral of the off the shelf computer continues...
