Any progress on it? There is another Leadsol.mxmf in the vectors directory.

I think it is ready to review, as it works well.

Leadsol.mxmf and testmxmf.mxmf are exactly the same file. And mxmf is the mobile version (lite) of XMF.

If you want more examples, here is a huge stash of phone tones that include more mxmf files, and none of them work. Look for the ones by the manufacturers Danger, Nokia, and Samsung: http://onj3.andrelouis.com/phonetones/

Another example with the name "Dancehall.mxmf" was included in the examples of the "Nokia Audio Suite 2.0", that is not available anymore since the Nokia forum was closed.

But anyway, you may see the pattern: only phone tones are available, and there is no example of the XMF (non mobile) format, and most of the mxmf available examples do not work.

Actually, EAS can play Dancehall.mxmf, and you can hear it:

dancehall.mp4

and none of them work.

I rescued commented loggings and found some details:

Danger:
Positive gain [6553600] in DLS wsmp ignored, set to 0dB
Unsupported DLS sample format 0055
Error converting XMF DLS data: -15
Failed to prepare EAS data and stream handles

Nokia:
No SMF data found in XMF file
No SMF data found in XMF file
CheckFileType returned error -17
Failed to open file

Samsung:
DLS data must precede SMF data in Mobile XMF file
DLS file contains invalid #articulations [0]
Error converting XMF DLS data: -17
Failed to prepare EAS data and stream handles

EAS's XMF parser does not support:

• ZLIB unpacker (which is not required by MXMF specification, but widely used in Nokia's MXMFs)

EAS's DLS parser does not support:

• WAVE_FORMAT_MPEGLAYER3 sample format (used in Danger's)

DLS in Samsung's does not seem to have articulations, and EAS complains about that.

BTW I think logging really should be enabled and put in use, as error codes contain very limited information and almost useless in this case. I could create a PR for it.
