How to disable verbose logging?

[Leadwerks]

The output messages in OpenALsoft are really excessive. How can I disable this?

By default a release build should only output error messages, and if you're getting a lot of them it indicates a problem somewhere. Non-release builds should output warnings and errors, which also shouldn't be much more. What output are you getting?

It's filling up our the whole console every time sound is used. My users generally do not care about the details of the sound system, as long as it works:

It looks like the log level can be changed in logging.cpp:

void al_print(LogLevel level, FILE *logfile, const char *fmt, ...)
{
    if (level != LogLevel::Error) return;

[kcat]

Unless you've made changes to the source, or have the ALSOFT_LOGLEVEL environment variable set, the default log level for release builds is errors only. It shouldn't show those messages if you didn't ask for them.
