Video is downloaded with what seems like half the audio, meaning it plays for a second and is silent the next second. This repeats the entire video. I had the same experience with another hls downloader. A third extension called Stream Recorder(https://chrome.google.com/webstore/detail/stream-recorder-download/iogidnfllpdhagebkblkgbfijkbkjdmm) was able to download the video with the complete audio track intact. Hope you can resolve that.
