I decided to have the Sony WalkMan reformat itself. MTP over USB working much better now.
Very odd that I could play MP3 recordings with the player without issues... only issues was removing files, copying new files to it. The thing that tipped me off to try reformatting the device with itself is I was seeing traces of recordings I had deleted yet in the playlist. Some of the letters in the listings were missing, but the content would still play properly. That told me deletes were not being completed properly. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1938645 Title: Ubuntu 20.04.2 getting kernel I/O errors connecting to Sony Walkman over USB using MTP protocol Status in linux package in Ubuntu: New Bug description: I use package Rhythembox as my MP3 player software. I also use Rhythebox to transfer audio to my Sony WalkMan MP3 player. Since moving to Xubuntu 20.04.2, it has gotten much harder to successfully transfer mp3 audio to the Sony WalkMan MP3 player.
