If you listen from USB (FLASH or HDD) files IMG+CUE (APE IMG+CUE, FLAC IMG+CUE, etc.) that does not work function SEEK - scrolling inside the playing track.
Rather, SEEK works only on the first track. If any other track is playing - 2, 3, 4 … and try to use SEEK, then there will be a switch back to the first track.
I’ve been testing all the versions for the last year. On any of them SEEK does not work.
In similar players - (RuneAudio and Moode Audio) - SEEK works fine on any track.
My board is Raspberry Pi 3 Model B
upd
I just installed - Volume for PC (X86 / X64) volume-2.413-2018-06-21-pi.img
SEEK also works only on the first track. On all other tracks - as well back on the first track.
