When I ask for the Read aloud facility in the ESV it skips from one chapter to the next. Sometimes I might hear 'Chapter Four' followed immediately by 'Chapter Five'; and sometime I hear nothing, or even hear truncated titles ... 'Chapter Sev", "Chapter Ay".
This only happens with narration by David Cochran Heath. The System Narrator is working fine.
I am connected to a fast broadband system ... so I do not believe that it relates to that.
This was happening yesterday as well as today.
