I have downloaded to my computer some song tracks in MP3-0. I have burned this to a CD-R but although the disc plays and it shows the number of tracks, no sound. I note from the technical specification that it does not do MP3 CODEC. I have a choice of MP3-0, MP3-320, FLAC, AAC, Ogg Vorbis and ALAC. Can you please tell me which I should use to get the CD to play on the Walkman. I use Burnaware to burn the tracks and as they were MP3 files I selected the MP3 Disc option, there is also Audio option.
