The PS4 Slim doesn’t have an optical audio output port, so you won’t be able to use this method if you have a PS4 Slim.
If your speaker doesn’t have an optical port, you can buy an optical adapter. For example, you would use an optical-to-RCA adapter to connect an optical cable to traditional red-and-white (analog stereo) speaker ports.
If you don’t hear anything, adjust your speakers’ volume.
Make sure your extractor’s audio output (e. g. , RCA) matches your speakers’ audio input. Be aware that the audio quality you will receive from an audio extractor will be inferior to the quality you would receive from plugging into your speakers.
If you don’t hear anything, adjust your speakers’ volume.
If you have a pair of headphones which uses a hardwired auxiliary cable, just plug that into the controller.
If your aux cable isn’t connected to your PS4 controller, this option will be greyed out.
Short of buying a Bluetooth transmitter which may or may not by supported by your PS4, there is no way to connect your Bluetooth (wireless) speaker to your PS4 without a cable. Virtually all Bluetooth speakers have a headphone jack somewhere on them for manual access. If for some reason your speaker doesn’t have an audio jack (or the audio jack is broken), you can’t use it with your PS4.
Depending on your other PS4 settings, this option may already be selected.
Disconnecting your speaker’s cable from your controller will usually shift the audio usage back to your PS4’s main speakers (e. g. , the TV speakers).
