AC3/DTS passthrough feature ignores EAC3 format passthrough.

[Sumea]

Describe the bug
SMplayer includes feature to passthrough AC3, also known as Dolby Digital and DTS, also known as DTS formats and their modern HD age lossless versions such as TrueHD. Even if the setting does not mention them, almost all types of D-labs and DTS formats are passed through HDMI with this setting, but not EAC3 also known as DD+. Standalone mpv player can pass this data through though with the right setting.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Settings'
2. Click on 'Audio tab, AC3/DTS audio passthrough with S/PDIF/HDMI connection.'
3. ???
4. EAC3 data is still handled by player in software rather than passed through to amplifier.

Expected behavior
EAC3 data should be passed through with this option same way TrueHD and such formats are.

Your Enviroment

• SMPlayer version: 24.5.0, QT 5.15.2, MPV v0.39.0-527-gd82701976
• OS: Windows 11
• Multimedia engine you're using with SMPlayer (preferences -> general):
  [ ] MPlayer
  [X] MPV

Logs
Likely no logs since this seems more of oversight than bug issue.

Additional context
The issue can be forced down by writing a setting into mpv.conf and commanding SMPlayer to use the mpv configuration, but this is problematic for people like me who use different devices in different contexts, as AC3/DTS passthrough option halts playback of any files with DTS/AC3 sound when using more conventional sound devices until disabled. Of course if possible, some sort of autodetection for S/PDIF and HDMI connections or easier access to the toggle could be feature requests.
