Following the firmware upgrade of my Sansa Clip+, I noticed it was accepting and playing AAC (.m4a) files. This applied to files ripped from CD by iTunes and files purchased from iTunes.
I have not found any mention of this anywhere on the web. Was this planned? Whether it was or not, it works…
I have the updated firmware and tried an AAC file. No go.
Sounds like you have badly named MP3 files.
No, the files are correctly named. But the “miracle” has nothing to do with the Clip+. The credit belongs to Winamp.
When using Winamp to load files onto the Clip+, it converts them to MP3. I was too excited to look at the files on the device itself. They end up with the extension “MP3”.
