I have a Samsung Galaxy S21-U running Android 14 and Termux 0.118.1 (retrieved from F-Droid on 2024.08.22) with TigerVNC 1.10.1-41. TigerVNC and associated required packages retrieved via apt in termux: I followed these steps to bring up an xfce4 desktop environment via tigervnc.

Instructions for getting sound output are harder to find.

1. The following solutions successfully played MP3 files over USB-C speakers:
   • The command play-audio from this answer (mpg123 and play produce no output, but see [2] below);
   • These instructions on reddit for the mpv command;
   • I cannot get output over the phone speakers from either of the above.
2. The VNC subset of this answer does not work for me
   • A virtual pulseaudio sink auto_null.monitor exists.
   • The commands play and mpg123 seem to attach to this sink.
   • With the above inputs attached, the sink auto_null.monitor switches state from SUSPENDED to RUNNING.
   • With audio playing, the xfce4 volume control panel shows the volume fluctuating.
   • No sound is emitted over either the phone or USB-C speakers.

I want to see if I can get the pulseaudio command play to emit over the phone speakers. Has anyone achieved this?
