Can't make work example play audio from SDFAT to BlueToot

[Marco1971Repo]

I'm trying to play sdfta to my bluetooth hedphone without success.
The sample [player-sdfat-audiokit] work as expected.
No way (for me obviously probably i'm doing something wrong but I don't understand what) to make work player-sdfat-a2dp..
Then I tride to change [player-sdfat-audiokit] removing kit as an output and adding A2DPStream (below the sketch) and the result is a failure initializing SD and i don't understand why

Why don't you use the tested examples.
For problems with the SD drive did you read the Wiki of the AudioKit project ?

[Marco1971Repo]

I did but it (player-sdfat-a2dp) fail:

[W] AudioA2DP.h : 271 - ==> state: Connecting
[W] AudioA2DP.h : 271 - ==> state: Connected
[E] AudioSourceSDFAT.h : 78 - sd.begin failed
[E] AudioSourceSDFAT.h : 111 - Filename is null
[W] AudioPlayer.h : 185 - -> begin: no data found

And this is what i don't understand since (player-sdfat-audiokit) work as expected so there is no problem with SD or at least I think so.

[Marco1971Repo]

I've solved the problem but onestly I don't understand to make work the player-sdfat-a2dp I need to add the lasta parameter setting it to false:
AudioSourceSDFAT source(startFilePath, ext, sdcfg, false);

The player-sdfat-audiokit work with the defalut value true....

Maybe you understand why and if it is a bug or not.

Hope is usefull for somebody else :-)

Thanks for your nice work.

[pschatzmann]

Hmm, this does not make any sense: The last parameter is just there so that the API is consistent with the AudioSourceIdxSDFAT class. However it is not used!

[Marco1971Repo]

I agree with you but....this is it.

To close this: I was not aligned to yor last commit.
Once aligned arduino-audiokit and arduino-audio-tools to your last commit everything has worked as expected.
