How do I turn the cache off?

How did you turn it on ?

Using Tim's command (has to be set after each boot) http://moodeaudio.org/forum/showthread.p...9#pid22699


Or Kent's  (permanent)  http://moodeaudio.org/forum/showthread.p...7#pid22767

If Tim's then just restart.  (Caching does not happen unless you rerun the commands each boot)
If Kent's then remove the additions and restart.

Thanks, will give it ago in the morning.

Just tried another quick test,

Base memory 18%
Added 4 tracks 19%
play track 1 26%
play track 2 28%
play track 3 32%
play track 4 47%

play tracks 1,2,3 & 4 again 47%

add track 5 47%
play track 5 54%

memory usage seems to increase in line with the length of the track, track 4 is 24 minutes.

I'm not sure I understand this, is memory usage considered a bad thing?  I have always been under the impression that unused RAM was wasted RAM as loading from RAM is faster than from HD or SD card?
As long as other processes are not starved of RAM & RAM is released allowing future tracks to cache, what is the problem?
I have not tried any of these cache settings being discussed, but if I saw my RAM usage at 90% I wouldn't be concerned.

No problem with memory usage, the test just prove that the tracks are NOT loaded to memory before they are played.

OK, I clearly misunderstood your tests.  I've started using the testing MPD & the 64bit kernel, just for the heck of it really, I have not viewed any logs as it's played music continually when I have asked it to, via a NAS & Tidal using bubbleupnp, it's not skipped a beat & sounds amazing.  No manual "tweaks" or amendments.
