Front end: Alternative audio tracks cannot be selected when direct playback is used

Kyoo's version

v4.7

What happened?

When using direct playback, alternative audio tracks show as "Unavailable in pristine":

This should allow for selection of audio track and should switch to HLS playback. The menu is available when switching from pristine -> auto or a specific resolution -> pristine, but it doesn't actually do anything.

automatically switching from pristine to auto should trigger a snack
