Dear all !
I'm using neutron to play music on my android mobile. Its very good !
I splited music to several folder and play each folder.
But when i updated the new version I cannot play in a folder that I have played ok before. Its lossy music. I deleted and recopy it but still cannot play.
Please tell me how can I do to fix it ?
I'm using Neutron version 1.81.1, mobile lenovo P780, android 4.2.
Thank you to read it !

Hi! Neutron does not play but list tracks? Would you please clarify. Have you trying to re-scan source entry (Sources -> long press source entry -> SCAN) to refresh Neutron's database completely. Are those files can be played by Neutron if you launch playback from the file manager? If you tried that would you please e-mail one such file for study and debugging to: neutronmp@gmail.com
