Not directly, but you can use something like Google Chromecast (here in the shop "Google Chromecast with Google TV HD") and simply connect it to the beamer with HDMI.
For good sound, however, you need an AV receiver and good speakers. Modern AV receivers have everything built in. Here in the shop, you can filter in the category "AV Receiver" for devices with "Chromecast built-in". But you can also consider buying a media server with all the smart TV apps (Plex, Netflix, YouTube, etc.) and connecting it via cable. Or just buy a used PS4, which can do all that (but only playback with Plex) and then you can also play games. I also have a NAS with a Plex server, but that also works with any computer.

I haven't tried it out, so I can't help you. The beamer has its own internal loudspeaker, which I think is sufficient.
