I am having an issue with audio Passthrough since #701 up to #707
• Using #630 when playing videos the amp indicates it is receiving Dolby Digital or DTS correctly
• Using #701 onwards the amp shows PCM for videos that are being correctly identified by #630.

However from #701 onwards
• If I disable audio Passthrough in Settings and then enable it again it makes no difference all shows are detected as PCM
• If I disable audio Passthrough in the playing video and then enable it again the audio is detected as Dolby Digital or DTS as appropriate
• After this If I stop the video  and start it again the audio may be detected correctly some of the time but not always

I am using a RPI 3. I have been updating daily for some months and have only seen this issue since #701
