Change default audio stream
One of the good things about roku, is that if you choose an audio stream other than the first, then it will always use that stream type in other media by default.
Most of my media has 4 streams:
1 - AAC 2 channel Dolby Pro Logic
2 - AAC 5.1 DD
3 - AC3 2 channel Dolby Pro Logic
4 - AC3 5.1 DD
Is it possible to amend the PfK config file to default to AC3 5.1 DD if it exists and if not fall back to the first stream?
