On my HTC One M7 with Android 5.0.2, Sense 6.0 on Verizon, I am unable to load music files or ringtones that the Music App or system will access. I have tried loading files using HTC Sync Manager on a Mac and copied files using a PC and Linux to Music and Ringtone Folders. The files are on the phone, but the phone's apps do not see these files. When I try to browse to add a Ringtone to a contact, the only ones shown are the system defaults.
I have VLC player installed and I can navigate to the files through the directory browse, but the Audio listing is empty. It looks like Android is not updating the Music files database info when these files are added to the phone.
Has anyone else experienced this issue, and found the solution?
