the book for my 15.5 S60 says it'll play 44.1/16b wav audio.
but I can't get it to play. Is there additional meta-data that needs to be attached or changed?

 

WAV is the raw data encoding used on music CDs - and there is some meta data you'd need. (look at a music CD on your PC to see what I mean) The 44.1/16 refers to the sample rate and bit depth of the encoding - which happens to be the music CD standard (DVDs often use 24 bits to create an audiofile quality S/N and to move any quantization noise out of the audio range). The easy fix is to simply burn a music CD, or rip your music to high sample rate MP3s and gain a 5-10x compression. Not sure if you are trying to use a memory device to store the media. I'd be curious if you'd be able to do a disk or file copy on your PC to put the music CD into a folder on your drive. My VW CC reads SD cards so I may see if it can read WAV and try this experiment myself. Another option is to simply download from Youtube using a web app like YouTube to mp3 Converter. If you are recording your own music, you may want to shop around for a WAV meta data editing app. There's a few online ( I have Audacity on one of my PCs)

 

I figured it was meta. Darn the Luck ! ! !
No - it's a band I work with and the car is always a good reference for mixes. I converted to m4a with XLD. Thats should work. I wanted "source" audio, but the m4a will do. I'd have thought that XLD would have done the proper meta when I took the mixes from 24b to 16b.
The music is on a USB thumb with all my other music.

 

I drags the tunes into iTunes and added some info then dragged them back to the drive.
See what comes.

 

I had the same problem with some of my computer filed music.
I found a freeware ripping program and "ripped" the files to MP3 and no problem.


Until there is a de facto standard for ALL music files the MP3 seems to be MOST universal.
A friend sent some I tunes files and it wouldn't read but after contorting to MP3 all is well.

 

I've tried a few methods and metadata editors. So Far, NG.
Tried m4a and just went back to wav 44.1/16b. But there are other discussions on other Volvo forums of the issue with both MP3 and other "supported" formats.
