True, but since then ProffieOS 8.x was released, so that is the new recommendation.
This is not a thing, you can’t have different config.ini files for different alt folders.
The new code requires battlvl to be in the same directory as your voice pack. (because it is a voice pack sound.) There is a define to change that, but if you use that define, then you can’t have voice pack in alt directories anymore.
Not sure what’s going on with trloop.wav though.
I recommend using “effects” in the serial monitor to check that the sounds have been found correctly.
This could be a slow sd card. Do you see “buffer underflow” messages in the serial monitor?
You’ll need to run the “effects” command din the serial monitor, and record the output of that.
Please note that “effects” is not available if you have DISABLE_DIAGNOSTIC_COMMANDS in your config file.
Those “NULL POINTER!” are a bit concerning though, that’s not supposed to happen…
