This worked on an older model discman with the same issue. Hold down menu button while lowering the volume bottom all the way down until avls indicator turns off.

Thanks for the information to disable AVLS. I was listining to my Sony D-Cj01 and this happend to me to were I could hardly hear the music, what a big annoyance. What kind of a stupid feature lets you turn the volume down but not be able to turn it back up?!?!?!... Thats just stupid. Brandon

Thank you so much felbalart! It's been driving me crazy. This is so much better!

I also have a d-cj01, and had the unremovable AVLS problem.. I read it on the manual, and the way to toggle it on/off is by pressing the SOUND button for a couple of seconds.. hope to help good luck!
