I have some mp3's ripped from a language CD, "Lesson 1", "Lesson 2" and so forth. Some of them are uploaded to iCloud with iTunes Match, for some it says "Ineligible". I don't really need them in the cloud, but on my iOS devices. How do I get them there, as the music sync is disabled when iTunes Match is turned on?
You can still sync audiobooks.
What you will need to do (as a work around) is import the CD as an audiobook (instructions here) then when the device is connected to iTunes you can choose to sync audiobooks.
