I have only experienced the issue on live streaming.... have watched programs that I have recorded and playback worked fine... no out of sync. appears to be primarily on live streaming.
Add another one to the "xfinity sound out of sync" crowd. Reading these posts, it's very obvious there is a problem, and Roku's generic "change this setting " reply is useless. I notices Amazon now has an xfinity app as well,and more features. All the dvr features,ability to pause live tv,and all. Maybe roku can get Amazon to fix this.
