Solved! If my projector volume doesn’t work can I still use Bluetooth

Solution
If you connect the soundbar to the audio output of the projector the answer is maybe.
If you connect your sources directly to the soundbar then yes. If you have more than one source and the soundbar doesn't have multiple HDMI inputs then you would need an HDMI input selector with audio extraction.
