Dear alsa-users: This is my first message. Slackware upgraded a few dozen packages Mon Aug 16 05:28:16 UTC 2021, including pulse. Since then audio has malfunctioned. When I run: alsactl init I get: alsa-lib parser.c:2137:(parse_toplevel_config) Incompatible syntax 4 in /usr/share/alsa/ucm2/ucm.conf alsa-lib main.c:1014:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -22 [/quote] amixer scontrols returns only: Simple mixer control 'Master',0 Simple mixer control 'Capture',0 It's never done that before. ucm.conf is the same it has been for months. I don't understand the messages. The first line in ucm.conf is: Syntax 4 so I suspect some incompatibility, that some alsa-using software expects a different syntax so some of the capabilities of my audio hardware aren't being controlled. I update Slackware daily. I build my own kernel, am using 5.13.11. My alsa packages are: alsa-lib-1.2.5.1-x86_64-1 alsa-oss-1.1.8-x86_64-3 alsa-plugins-1.2.5-x86_64-1 alsa-utils-1.2.5.1-x86_64-1 Thanks for your attention. russell bell _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
