GNU Linux (Debian) cheap chinese mp3 player JIE LI CD002-1 gets registered as Audio (Output) Device instead as usb drive (usb stick mount) file access impossible

11.Jul.2021

alternatives, Audio / Logic / Music, General / Allgemein, hardware fail

the catch: when there is no audio jack inserted ->

it will register as “audio output device” (usb-soundcard) by GNU Linux Debian X-D

making file access impossible

solution: attach a audio-jack cable:

then it will show up and mount like a usb-stick

another downturn of that (otherwise nice) product:

can not play audio while charging, making it unusable as a non-portable mp3-player for the user’s audio-rack
