DLNA renderer: Pure Jonga A240
For audio only,the pulseaudio-dlna package does the job on Ubuntu 19.04 despite some errors during install. There is a 12 second lag (on my setup) and some stuttering during volume adjustment. But simply amazing functionality and simplicity. It's the only I've way I've found to push internet audio to a dlna renderer via linux. There are a huge number of options for Android and an almost complete dearth of them for linux.
For pushing local video/audio content, it's a lot easier: install the Emby server (google for instructions), then hook up to the web-based interface of the server via a browser (on the linux PC itself or a browser on another device). The web interface gives you a media player complete with a "Play To.." option where your dlna renderer is visible.

@studiohack It's to an SU question and an software page, not instructions – HackToHell – 2012-05-06T04:33:21.180
1@HackToHell SU pages can be deleted... I was suggesting that you paste (with credit) or summarize proof of it being possible. – studiohack – 2012-05-06T04:34:26.103
