output in flac format is broken. I added extra tracing and for

csound tapped.csd --format=flac -o test.flac

i get

sfinit: cannot open test.flac, Not a valid SNDFILE* pointer.

In file InOut/libsnd.c function sf_openout line about 788
No idea yet

did you try testing libsndfile separately using its utility programs?

It’s working here OK on OSX. I can produce a correct FLAC file with your command line.

I had multiple versions of libsndfile.  Cleaed up and only one copy now 
but still a probem:

sfinit: cannot open test.flac, Internal error : SF_INFO struct incomplete.

Still cnfused!

it is pointing to libsndfile not supporting flac in your system.

I definitely have it built with flac/ogg/vorbis support.  It seems to me 
that v25 is OK  (just tried on a different Linux computer) but v29 fails

Hi,

tested on OpenSuse 42.1, Csound 6.09 (built on 4.05, thus not the newest), libsndfile1-1.0.25-27.1
and flac file output is created correctly. I guess it is not Csound's problem but of that particular sndfile version.
