Gulp: How to use Browsersync, Sourcemaps, Autoprefixer and CSS Cleaner together? - sass

Question

See below. The problem I'm having with my current code is that Sourcemaps aren't getting injected via Browsersync. Am I missing something here or doing it the wrong way?
For reference:
https://www.browsersync.io/docs/gulp/#gulp-sass-maps
// requirements
var gulp = require('gulp');
var sass = require('gulp-ruby-sass');
var browserSync = require('browser-sync').create();
var prefix = require('gulp-autoprefixer');
var rename = require('gulp-rename');
var sourcemaps = require('gulp-sourcemaps');
var cssclean = require('gulp-clean-css');
// create sass tasks
gulp.task('sass', function() {
return sass('assets/scss/style.scss', {sourcemap: true, style: 'compact'})
.on('error', function (err) {
console.error('Error!', err.message);
})
.pipe(rename({suffix: '.min'}))
.pipe(cssclean())
.pipe(prefix("last 2 versions", "> 1%", "ie 8", "Android 2", "Firefox ESR"))
.pipe(sourcemaps.write('.'))
.pipe(gulp.dest('assets/styles'))
.pipe(browserSync.stream({match: '**/*.css'}))
});
gulp.task('serve', ['sass'], function() {
browserSync.init({
proxy: "localhost/portfolio2014",
open:false
});
gulp.watch("assets/scss/**/*.scss", ['sass']);
gulp.watch(["assets/styles/*.css", "site/**/*", "content/**/*", "assets/javascript/*.js"]).on('change', browserSync.reload);
});
// default task (just run gulp)
gulp.task('default', ['serve'] );

Do you have to use gulp-ruby-sass? The gulpfile.js below is adding sourcemaps with gulp-sass and updating the browser when saving .scss files with sourcemaps.
var gulp = require('gulp');
var sass = require('gulp-sass');
var browserSync = require('browser-sync').create();
var prefix = require('gulp-autoprefixer');
var rename = require('gulp-rename');
var sourcemaps = require('gulp-sourcemaps');
var cssclean = require('gulp-clean-css');
// create sass tasks
gulp.task('sass', function () {
return gulp.src('assets/scss/test.scss')
.pipe(sourcemaps.init())
.pipe(sass())
.pipe(rename({ suffix: '.min' }))
.pipe(cssclean())
.pipe(prefix("last 2 versions", "> 1%", "ie 8", "Android 2", "Firefox ESR"))
.pipe(sourcemaps.write(''))
.pipe(gulp.dest('assets/styles'))
.pipe(browserSync.stream({ match: '**/*.css' }))
.on('error', function (err) {
console.error('Error!', err.message);
});
});
gulp.task('serve', ['sass'], function () {
browserSync.init({
proxy: "localhost/portfolio2014",
open: false
});
gulp.watch("assets/scss/**/*.scss", ['sass']);
gulp.watch(["assets/styles/*.css", "assets/javascript/*.js"]).on('change', browserSync.reload);
});
// default task (just run gulp)
gulp.task('default', ['serve']);
