The mystery of the 14 invisible AAC tracks 2017-12-05 02:11:51 Hi everybody,I have one centralized music library, and I use two different foobar installations, on two separate PCs, to access it.The first foobar (1.3.9) sees all the tracks in the library (47.289).The second foobar (1.2.2) sees all the tracks except 14 of them (47.275).I have quickly found that the 14 tracks are 14 AAC256 tracks (.m4a), out of my total 321 AAC tracks.They are not corrupted or anything : they exist, and they all play fine in my first foobar, just like the other AAC tracks.Weirdly, these 14 tracks are all from the same compilation (they are in the same HDD directory).They are the only 14 AAC tracks in that directory (the other tracks in that same directory are mp3).That directory has no naming issues or anything.They all have the same characteristics according to foobar : 254 Kbps, codec AAC, codec profile AAC LC, 44.1 KHz, Stereo.I shouldn't care much about only 14 tracks, but I'd like to know the reason, and if there's a solution or a workaround.So, oan somebody explain why this is happening ? Thanks. PS : please don't tell me to update my second foobar. I'll update the first, but I'd like to keep the second that way. Thank you.
