PCM and Apple Lossless Music

[terence]

I'm brand new to the forum. Hello everyone!

Just took delivery of my 4S. So far very good. Does anyone know if the PCM can play Apple Lossless files? I put my music collection on a pen drive and plugged it in the car. The PCM reads the contents but cannot play the music (it says error). Any thoughts/experience?

Thanks in advance.

Apple Lossless should be a file with a .m4a extension. According to the owners manual, that should be fine.

File extension

.mp3;.wma;.asf;.m4a;.m4b;.aac;.flac;.mpg;.mpeg;.avi;.mp4;.m4v;.mov;.wmv;.3gp;.mkv;.ts;.mid.xmf;.mxmf;.rtttl;.rtx;.imy;.ogg;.webm;.wav

Thank you! I tried downloading Amazon Music and play it through the app but same results. Has anyone tried and succeeded in playing .m4a files?

Be aware that M4A files from Apple Music may be DRM-protected and not playable outside iTunes/MacOS/iOS.

Where have you played those files previously?

I just tested both m4a and flax audio files. Both played fine. Macan4S/USA

I put 3 files on the drive (.m4a, .flac and .wav). Only the .m4a does not play. They other play fine. Any thoughts? I'm in the UK btw

Do your .m4a files play on other devices or cars?

I bet the files are DRM-protected.

I also suspect the .m4a files that do not play are DRM protected. The .m4a file I tested with (see post above) is not. That file does play on other devices (Mac QuickTime Pro, Sonos).

I have played it on other systems (VLC on windows and android, and some others) but it's all fine. Is there a way of telling if it's DRM?

To check if a song is DRM-protected, particularly in iTunes/Apple Music, right-click the song, select "Get Info," and look under "Kind" on the Summary tab. If it says "Protected AAC audio file" or similar, it's DRM-protected.
