[mythtv-users] Ubuntu-mate on Raspberry pi and mythtv library problems

[Bob Sully]

Edit:  Changed the "use internal volume controls" to checked, then 
changed the mixer device to "OpenMAX", then unchecked it again.  I now 
have sound, but it's rather iffy:  one of the recent "Game of Thrones" 
episodes had no sound during the minute or two of the previous show, but 
soon as the GoT episode started, sound came on.  Video playback on 
recordings (now that I've actually watched one long enough to tell) is 
now behaving like the other videos - quite choppy.

So it looks like if I can get the video playback issue on Myth fixed, 
it'll be usable.  Any advice?

Thanks - Bob
