alsa-project/alsa-lib issue #312 was opened from leif1992: I got a problem which confused me for a long time. Wish I can get a good answer from here. I write the ucm and ucm2 files for my sound card which can work well with my driver. And I need to support both 4.19 kernel (which use the ucm) and the 5.4 kernel (which use the ucm2). They are all deployed in the /usr/share/alsa. However, I need to install to audio driver for both 4.19 and 5.4 (DKMS). The ucm and ucm2 were both deployed at the same time. When I switch the kernel to 5.4, my ubuntu can't load my UCM files normally, and if I removed the files in the usr/share/alsa/ucm and then reboot the OS. My ucm files in the usr/share/alsa/ucm2 can be loaded normally. Would you please help me figure out this incompatibility problem?
