alsa-project/alsa-utils issue #120 was opened from svarshavchik: I'm using alsa-utils 1.2.5.1 on Fedora 35 (alsa-utils-1.2.5.1-2.fc35.x86_64) There are two audio devices, built-in audio and a USB audio device. After a reboot the default audio output gets reset to the USB audio service: $ pactl get-default-sink alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo After resetting it back to built-in audio: $ pactl set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo $ pactl get-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo This persists until the next reboot, when it gets reset back to the other device. While perusing system boot messages the following caught my eye: Nov 18 07:05:58 monster.email-scan.com systemd[1]: Started Manage Sound Card State (restore and store). Nov 18 07:05:58 monster.email-scan.com alsactl[3870]: alsactl 1.2.5.1 daemon started Nov 18 07:05:58 monster.email-scan.com alsactl[3870]: alsa-lib parser.c:242:(error_node) UCM is not supported for this HDA model (HDA Intel at 0xfa9f8000 irq 47) Nov 18 07:05:58 monster.email-scan.com alsactl[3870]: alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6 Nov 18 07:05:58 monster.email-scan.com alsactl[3870]: alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:1 use case configuration -2 The fedora package starts alsa like this: /usr/sbin/alsactl -s -n 19 -c -E ALSA_CONFIG_PATH=/etc/alsa/alsactl.conf --initfile=/lib/alsa/init/00main rdaemon and stops it like this: /usr/sbin/alsactl -s kill save_and_quit Stopping/restarting logs the same errors again. Not sure this is related to the default audio device getting reset on boot.
