You can activate both speakers on your Nexus 5X for better audio experience. The ‘Surround sound’ mod for Nexus 5X activates both speakers on your phone while listening music watching videos and playing games. Note that this mode will not give the same experience as a dual speakerphone gives, but you will definitely have a good audio experience.

Just like any mode, the Surround sound mod has also required a rooted phone. You can install the mode in a couple of ways, either by manually pushing the required files to system/etc and set permissions to rw r r, or just flashing the zip files via custom recovery. This guide is going to assume that you are already pretty savvy with tweaking Android OS and that you have got TWRP installed on your Nexus 5X and root access.
