Fix: Remove conflicting metadata assignments to resolve audio switchi…

…ng issue on Roku

- Removed the line `m.LoadMetaDataTask.selectedSubtitleIndex = m.top.SelectedSubtitle` from onAudioIndexChange()
- Removed the line `m.LoadMetaDataTask.selectedAudioStreamIndex = m.top.audioIndex` from onSubtitleChange()
- These removals address a race condition causing video playback to fail when switching audio tracks

Fixes #2059
