Sansa C250/ How do I find my music files?

[Keith_Beef]

Do your ogg files have correct tags? Are they showing up as "" in the database?

I cannot see any of those ogg files in the database.

They are tagged, I mounted the c250 and verified the tags using AudioTagTool... they simply do not show up in the database. database autoupdate is on, I tried re-initialising the database, too.

When I look at for example /MUSIC/badly_drawn_boy/have_you_fed_the_fish/all_possibilities.ogg, rockbox tells me:
all_possibilities.ogg
(root)
(root)
Next:

as if playing the file, but no sound comes out.

In fact, no sound comes from "playing" a file, I only get sound when playing a selection from the database...

I also have a problem with the display and controls...
I can set the backlight timeout, and wake up the display after a few seconds of it darkening.

But if I let the screen darken and I don't touch a control before the next song has started, then the controls become mostly unusable.

The menu/power button switches the device off, the volume control works, but other controls don't work.

This doesn't really help, but this particular problem sounds related to this fellow's issue...

What kind of tags do your ogg files have? Rockbox only allows a music file's "native" tag format which would be vorbis comments for ogg files but some pc tools allow other tags too.

Ever felt stupid?

I finally tracked this down.

Thinking that it might be a problem with variable bitrate, I went back and verified the files I was copying to the player...

It turns out that I must have badly configured my ripping software, because the files had a .ogg suffix but in fact were encoded as MP3s!

I went back and re-ripped them to OGG Vorbis format, and everything works.

The lesson might  be that the Rockbox firmware looks at the filename suffix and then tries to use the corresponding codec, rather than the real content (or the magic number). Of course, with a file encoded as MP3, but with an ogg suffix, this isn't going to work, so there's an error.

similar situation here.  c250 running latest rockbox release, selected 'show all files', boot to rockbox, connect to pc, reverts back to sansa firmware and when move files in MTP mode rockbox can't see music files/video files. Only when move files in MSC mode, rockbox can see and play files. it's annoying if i have to move recordings and music files often. any way to get around this?

Not that is currently known. MSC transfers files over directly. MTP uses a Microsoft PlaysForSure protocol that doesn't work with rockbox.
