The songs play for about 20 seconds in iTunes/Music and then skip to the next song for converting and end up with “conversion failure”.
Step 1. Please check whether the system is connected to any audio output device. If it is, please disconnect the external audio device (including the audio devices connected by Bluetooth, like speakers or headphones).
Step 2. Restart your computer and convert the songs again.
