[SOLVED] Auto-shuffle does not appear to work

[cricalix]

Hello folks, new moOde user here.

I went looking for how to set up a random playlist of my entire library of music that's held on a NAS. Found the advice that mpd is not great at playlists over a few hundred items, and I've got over 16K tracks. Same post said to use auto-shuffle, and then moOde should just do the right thing (http://moodeaudio.org/forum/showthread.php?tid=653).

Alas, it moOde does not appear to do the right thing, or I'm doing the wrong thing.

Test 1:

• Load playback view
  
• Clear the queue
  
• Navigate to NAS/Vault/<artist>/<album> and add one song to the playlist
  
• Click the playback bar to go to the playback view
  
• Click play
  
• Playback of selected song starts
  
• Click next track
  
• Playback of selected song starts again from the beginning of the track
  

Test 2:

• As with test 1, but before clicking play, click the shuffle/random icon
  
• Same behaviour as test 1 for play/next track
  

Test 3:

• As with test 1, but before clicking play, click the triple dot, tick Consume
  
• Same behaviour as test 1 for play/next track
  

Test 4:

• Repeat test 2, but enable Consume
  
• Same behaviour as test 1 for play/next track
  

Test 5:

• Load playback view
  
• Remove entry from queue
  
• Ensure consume is not set
  
• Ensure random is not set
  
• Click play
  
• Nothing happens
  

Test 6:

• Test 5, but with consume set
  
• Same result
  

Test 7:

• Test 5, but with random set
  
• Same result
  

Test 8:

• Test 5, but with random and consume set
  
• Same result
  

Test 9:

• As with test 1, but add two songs to the playlist
  
• Switch to playback view
  
• Enable consume
  
• Enable random
  
• Play
  
• Next track - first played song is consumed
  
• Next track - no new tracks are loaded from the library, current song restarts
  

Test 10:

• Audio settings
  
• Disable auto shuffle
  
• Enable auto shuffle
  
• Don't change from Track and None
  
• Go to playback view
  
• Click triple-dot to check Consume setting
  
• Consume is not ticked (quick help says it's enabled by auto-shuffle)
  
• Random is not enabled (enabling auto-shuffle does say it disables random)
  
• Click play
  
• Nothing happens
  

Test 11:

• Audio settings
  
• Change filter to: artist dido
  
• Library
  
• Search "dido" to confirm matches are found
  
• Playback view
  
• Play
  
• Nothing happens
  

Debug log shows nothing like failure messages.

Could be out-of-memory issue. Auto-shuffle uses RAM to store the randomized collection of tracks.

To troubleshoot try running it from command line and look for error messages,

1. Turn it off in Audio Config.
2. Run command below

Code:

/usr/local/bin/ashuffle --queue-buffer 1

Well, right after doing all that testing, I noticed that somehow the albums/tags view was only showing a few albums despite scanning the entire NAS share; the random/star icon was pretty much only loading three different albums, despite browsing to Library/NAS/<name> showing all of my albums.

I deleted the library, updated the library from the M menu, re-created it, and re-updated.

Reset the auto-shuffle to on, cleared the filter.

Went to playback. Ensured nothing was in the queue. Ensured consume was set. Clicked random to get it highlighted. Clicked play. 10 seconds later (mpd is still indexing the NAS, so the Pi is struggling a bit) two random tracks popped into the queue and the first one started to play.

(We crossed Tim, I was writing this as you replied.)

Looking at memory usage, I think the Pi is doing ok - 112 MB used, 236 MB for buffer/cache, 92 MB free.

I suspect that somehow perhaps mpd wasn't very happy, given the fact a library reset appears to have fixed everything (with no reboots). The UI is struggling to keep up with what's actually playing at the moment, but I'm going to put that down to the (in modern terms) fairly anaemic Pi Zero processor that's busy with all of mpd's work to index the library.

Thanks for the really quick response.
