Hi fluid-dev team,
We at Notation Software (see www.notation.com) use libfluidsynth under the LGPL
license.
We have created the libfluidsynth dll libraries for "dsound" and "portaudio"
where we use the Steinberg's ASIO underneath.
Our default setting is with the "dsound" configuration. The customer can
optionally select the portaudio/ASIO settings for e.g. realtime recording.
We have a customer error report where the software crashes at the very first
fluidsynth statement "settings = new_fluid_settings();"
An investigation showed that the customer uses an exotic audio card where the
initialzation of the portaudio/ASIO/card driver software causes a crash for
whatever reason.
When using a libfluidsynth library w/o portaudio support all works fine.
Issue:
=====
Even when only "dsound" is used, the portaudio software is started by
"new_fluid_settings()" and causes that crash.
When the libs are statically built with #define PORTAUDIO_SUPPORT, in any case
the call of "new_fluid_settings()" performs an initialization of the
portaudio/ASIO/sound card through "fluid_settings_add_option (settings,
"audio.driver", "portaudio")".
Solution:
=======
A fault tolerant solution should activate "fluid_settings_add_option (settings,
"audio.driver", "portaudio")" ONLY when portaudio is actively selected and not
by default when the libs are statically built at th beginning.
Question:
=======
As I have not found anything in any forum whether an option exist, is there a
possibility to dynamically set the "portaudio" initialization?
Such a solution is trivial but as mentioned we use libfluidsynth under the LGPL
license and want to keep the software unchanged.
Does anybody can provide an advice what would be the best way to address this
issue?
Any helpful advice is highly appreciated.
Best regards,
Reinhold
