(Specifications) If a music was being played via USB when the audio system was turned
off at the last time, the audio system is to resume playing the same music automatically
when the same USB is plugged in at the next time. (Trouble Symptom) The system does
not resume playing from the previously played music and starts to play from the first
music in the USB.
When resuming a USB audio playing after editing the folder structure and/or the order
of the music in the USB by PC, a mismatch between the played tracks and the displayed
track names occurs.
After indicating "Play Artist ******" via voice recognition, the user selects a specific
music on the displayed list to start USB audio playback. Then, instead of the music on
the list, the specific music from the first album of that artist will be played.
After all music has been played by USB audio with the repeat function in “off” position,
music cannot be played after pressing search to switch the playing mode (folder, artist,
album, etc.) and selecting a music.
