Dear all,

I used to be able to use amarok with my Sansa clip 8gb. I have not tried it for a while, today I tried again and it does not work.

I am on opensuse 11.3 KDE 4.6.1, and amarok .rpm from opensuse KDE unstable amarok-2.4.1.60git.1301241711-1.4.x86_64; note that same beavour with opensuse amarok stable amarok-2.4.0.90-114.2.x86_64.

MSC mode:
The device mounts OK in Dolphin and is connected, scanned, browsed and played for OK in clementine. Amarok does not see it. Here is the ldebug og:

MTP mode:
in MTP mode dolphin does not see it (tries to open 'camera:/'); both clementine and amarok do succeed to mount and display the player, but see only 2 songs on it (there are ~300). My libmtp is version 1.0.3-2.1.

here is the output from amarok debug:

Any hints?

Thanks, P

There's no documentation of this fact, but it was verified by someone from Sandisk on the Sandisk Clip forum. The files externally visible in MTP mode are in a disjoint name space from those externally visible in MSC mode. The Clip itself puts them together (or seems to), though I'm uncertain about the rules for that. But if you use Dolphin, say, to write files in MSC mode and then switch to MTP mode,those files will now be invisible to Dolphin, and vice versa.

I myself am struggling with how to get the Clip to play well with Linux playlists, particularly in Amarok. One problem is that the Clip wants directories delimited by \, DOS-style, but Amarok generates playlists that use / for that purpose. That at least is fixable with search/replace, but it shouldn't be necessary.
