Play m4a files on Windows 7

Which codec pack did you try?  I was just looking at K-Lite:
https://www.codecguide.com/download_kl.htm

And how many audio files are you talking about?  What type of content?  I
have to believe conversion to another format is possible.  Get a batch
convertor and process in bulk. I spoke to my brother who has been an audio
engineer for 2 decades and he says as long as you guys keep the sampling
rates/bit depths same, you'll only be changing format, and there shouldn't
be any loss in quality.

IMHO, even if you went to 192kps MP3, that's a pretty high bit rate, and
most "normal" people (non audio engineers) aren't going to notice any
difference in quality.
