[QUOTE="homercartman, post: 1079944, member: 414304"] Also, [USER=243342]@Captain Jack[/USER] [USER=410643]@fsphil[/USER] Since systeraudio option exists, the descrambled systeraudio level feels really low compared to audio level sent in clear. With the following patch, descrambled systeraudio level compares much better to clear level, but sometimes saturate. Maybe some computations are off in [icode]ng_invert_audio()[/icode]?
