<div dir="ltr"><div><div><div><div>Hello pulseaudio-discuss, </div>I am setting up a small linux computer (C.H.I.P.) to be a bluetooth receiver using pulseaudio. The device is not running X so I am working through pactl and configuration files. Everything is working except when my phone connects to the device pulseaudio always sets the sink-input volume to 0. </div><div>How do I get pulseaudio to set the sink-input and sink volume to 100%? Thanks. </div>I think these are the related pulseaudio debug lines: I: [pulseaudio] client.c: Created 26 "Native client (UNIX socket client)" I: [pulseaudio] protocol-native.c: Client authenticated anonymously.
