First time: after some scrambling around, I found that I simply have to switch to "Built-In Analog Stereo" in XFCE's (my desktop) audio mixer. Fine, so I wrote it off as a result of a one-time update to Pipewire.But this happened again, after the 2nd reboot.I saw nothing in audio mixer which lets me permanently set my default audio out.I searched for "pipewire default audio device" and "pipewire save default audio device" but didn't find anything useful. After browsing some random links I found mentions of a "pactl" command, so after reading its man page:$ pactl list short sinks41 alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo PipeWire s16le 2ch 48000Hz SUSPENDED 42 alsa_output.pci-0000_00_1b.0.analog-stereo PipeWire s32le 2ch 48000Hz SUSPENDEDAfter a reboot: $ pactl get-default-sink alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo Fail. $ pactl set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo Now I have audio again.After logging out and back in, the default audio is unchanged. But it gets reset after every reboot. After scratching my head, I looked deeper and discovered that pactl is pulseaudio, but my understanding is that F35 switched to something called "pipewire".More digging uncovered the existence of pw-cli. However its man page is sparse, and after starting it the "dump" and "list objects" command produced a ton of incomprehensible output. "help" didn't seem to have much help to say in terms of selecting and saving, permanently, the default output device. Wouldn't you think that this should be pretty basic, elementary stuff that any audio framework should put in front of the user, in a very visible way? But I guess not.So, anyone knows how to set the permanent default output device?No. But I do have a question.If you boot the system with the USB device disconnected, and then login, I assume sound works with the pcidevice. Then, if you plug in the USB device does it take over from the pci device?
No, it does not. $ pactl list short sinks40 alsa_output.pci-0000_00_1b.0.analog-stereo PipeWire s32le 2ch 48000Hz SUSPENDED 55 alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog- stereo PipeWire s16le 2ch 48000Hz SUSPENDED
Only the first entry, the built-in audio jack, came up after a reboot, and that's where the audio went by default. Plugging back the USB-Audio adapter did not change the default audio-out.
