With multiple sound devices available (internal sound device, HDMI monitor with built-in-sound, USB sound device), sometimes it decides to use a different one after one login than the last time. Many a time I've wished it was easily possible to just send sound to several devices simultaneously. With Mate's sound preferences the output tab determines what device is outputting sound (with some options about it). The hardware tab determines which hardware the volume control adjusts (with some other options). And it is possible to easily get in a state where the volume control (and mute) is associated with the hardware that's not currently in use. It was also possible to get into states where the pulseaudio software audio level controls before the hardware (each application's output in the sound preferences tab) is lowered. This can happen when lowering the volume in a youtube clip, for example, through the webpage. And then there were other hardware controls for the sound card, where you could end up with some channels lowered (or muted) while you were only controlling the master output through the desktop GUI. This could be controlled with alsamixer in the past, I don't know if it still is. In mixer terminology, various sound sources come into a mixer with individual level controls, and there's a master output volume control for the final mix. Sound has to go through the inputs on the way to the outputs, the master control is the output stage level control, it's not a one knob controls everything together. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
