Summary0001438: Opus streaming export --- unexpected volume ramp

When exporting to Opus, the beginning of the resulting file has a short volume ramping period for a fraction of a second. This mutes the first attack in songs. Such ramping is not present in wav or ogg exports.

Steps To Reproduce

Load a module, and stream using the File menu. Set Opus output, Q5, 48khz, stereo, play the entire song, normalize output. Examine the beginning of the file, and compare this to the wav and ogg outputs.

The volume ramping with Opus seems to occur regardless of the module.
