Or, at all. Occasionally my system doesn't find any audio hardware. Many of us are in this "which card?" boat, because of modern hardware being quite different from ye olde. There's the on-board sound, which may or may not have anything plugged into it (mine doesn't). A HDMI video monitor which may support sound (mine does). And we may (I do) have some USB audio hardware plugged in. While I could disable the on- board sound (assuming that a UEFI option really disables it and the OS doesn't find it again), I can't disable the HDMI audio and it is useful to be able to manually select it, some times. Somehow it's supposed to determine which one to use. And we'd hope that once we've set a preference in our login account (e.g. using whatever pulseaudio volume control app applies, in my case I'm using "mate-volume-control") it would stick. Ideally, these volume control apps need improving so that they clearly identify hardware precisely (not configure things to use the first found device method, when *we* know that's not a fixed answer), and write the config in such a place that it's paid attention to. I've had a look at the link in your next message: https://alsa.opensrc.org/MultipleCards But I may as well be reading NASA specs on the space shuttle, there's a presumption of prior knowledge. -- uname -rsvp Linux 3.10.0-1160.71.1.el7.x86_64 #1 SMP Tue Jun 28 15:37:28 UTC 2022 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
