I noticed, the BGM (background music) stops at 05:00 minutes playing time, when there are no user inputs / any activties.
It seems the music stops everytime after 5 minutes of inactivity. Is does not matter if there is a mp3 or ogg as BGM playing. I tried to press left/right to show another system on the mainscreen after 03:00 minutes. I thought the music would again stopp in 02:00 minutes (alsto total 05:00 minutes).
It does not happens. The playing tune was playing until end and automatical played another random tune. (as it should be) The music stopped again, exactly at 05:00 minutes while my last activation. I cant find any settings. Is this is a bug?
Edit:
I have connected an external HDD where all the ROM files and BGM is available and mounted. (Maybe a problem when using external drives and hdd idle mode?)
