Good. (Within the confines of DRM.)

That does appear to be a Clip Zip upstream stock firmware issue. I
say appear because I am not sure. I am just another happy user of the
Clip+. But I haven't had any any problems with the original
firmware. But I don't know if that means anything. In a software
program the smallest of details can cause the largest of problems.

If I were wanting to do that I would investigate converting the audio
into a non-drm format and then playing the non-drm format. So far I
have avoided needing to face this question. I am not familiar with
DRM10 but I saw that others posted some suggestions.

And it would seem reasonable to expect that if the original firmware
says that it supports it then I would expect that booting into the
original firmware should play them. What you have done so far seems
perfectly reasonable.

I would hope (without any actual information) that having rockbox
installed would not prevent the original firmware from doing this.
However note that I really do not know about this issue.

It is perhaps possible that the DRM code checks for the bootloader and
refuses to operate if it isn't the native bootloader. That would be
very annoying. But it seems likely that will be discovered to be the
case given what you have reported so far. Don't know.

Are you asking about removing rockbox and returning to the stock boot
loader firmware? Please verify the procedure from the current docs.
It has been at least two years since I did it myself on a player.

I think you are definitely to the point to try replacing the rockbox
bootloader with the original bootloader to verify if the player will
play your files without rockbox installed. If that works then that
sounds like your best option. (Although I would rather be hoping it
didn't since that would mean the problem was something else that would
allow rockbox to remain installed.)

If (and only if) that turns out to be the case and you are happy with
the DRM on the original player then if it were me I would buy a second
player. One for the DRM and one for everything else. Because
personally I really like the voice talker for the menus and other
features. I would hate to be without the wonderful features of
rockbox. But if that were the only way then that is what I would do.
Just an idea.

Good luck!
