hi, there,

i have a new install volumio 2.806 on raspberry pi 3b+,

volumio@volumio:~$ free -h -s 1
total used free shared buffers cached
Mem: 969M 572M 396M 8.7M 84M 301M
-/+ buffers/cache: 186M 783M
Swap: 0B 0B 0B

is it possible to release that 186M buffers/cache could use for squeezelite output buffer?
