opusdec playing decoded output audio

[eblanca]

I see opusdec is built with ability to send output to sound card when not specifying any output files.
This is because on my system I have alsa (or sndio) dev packages installed and they are detected during configure script.
Is there any ways to tell configure not to include them? (and having opusdec only decode into files)

Currently the audio playback feature is enabled whenever the associated header files are available. I agree that there should be a configure option to disable this, in order to create reproducible builds that do not depend on what optional packages happened to be installed at build time.
