Usb problems to load themes in denon sc2900

Good afternoon I have a little problemita when I assemble my folders in the usb to use them with the denon sc2900 there are some songs that are not loaded says cant open please help solve this problem :tired_face:

You probably have 48kHz files, use a converter to get them the standard 44.1kHz.

From the SC2900 user manual (page 4): Supported Media: WAV: 44.1kHz, 16bit/24bit Stereo AIFF: 44.1kHz, 16bit/24bit Stereo MP3: CBR/VBR 44.1kHz, Stereo 32kbps – 320 kbps AAC: CBR/VBR 44.1kHz, Stereo 64kbps – 320 kbps

I guess you don’t analyze files in Engine? Engine would also tell you they are not supported.
