I have an Ubuntu 21.10 (Impish Indri) pc connected to an avr receiver via HDMI. Each time I start a different program with audio or video, the screen on the receiver loads for a few seconds and then plays.
It's like each each program is sending a different audio profile to the receiver and it takes a few seconds to load on a sound profile, also the signal keeps going back and forth between 48 kHz and 41 kHz depending on the source.
Clementine does this and so does lollypop and chromium. Now why would each program take over the sound profile in the OS? What could be causing this and how do I go about solving it? I have my sound settings set on the settings app but it's like each program sends a different HDMI signal.This is a fresh install, it did not use to this on a previous installation.
***Here’s an update: I installed pavucontrol (Pulse Audio Volume Control) to help me figure out the problem. When nothing is playing in Ubuntu, the OS defaults to an HDMI “Analogue” signal and when I play anything it switches to “Multi-inch PCM”, which is why the avr receiver keeps loading a different profile on each program. Basically, Ubuntu keeps defaulting to an Analogue HDMI signal when there’s nothing playing. As of now, keeping Pulse Audio Volume Control open seems to solve this problem. If I can figure out how to tell the OS to keep sound output configuration without keeping pavucontrol open then I can solve the issue permanently.
