Incorrect behaviour

In the master settings for the console, there is a volume setting. I don't think it does anything.

Expected behaviour

The volume setting should do something.

Steps to reproduce

1. Start the console
2. Go to Settings
3. Increase the volume
4. Play a CD
5. Notice there is no difference in volume

Additional details

Forking from #12852 because this has a different cause and solution.

Aren't normal audio CDs supposed to work with CD-i?

Yes, but maybe the volume setting is not affecting CD-audio? I can't remember it from the CD-i days anymore since I didn't play my audio CDs with it.
