alsa-project/alsa-utils issue #146 was opened from mhampl: There are some weaknesses on current Ubuntu systems (e.g. release 22.04) where the alsa_info scripts does not deliver the desired information: The command "tree" is no more provided by default (but can be installed in addition) This results in the error message "./alsa-info.sh: line 661: tree: command not found" and causes missing output in "Sysfs card info" The command "dmesg" requires administrative authorizations (e.g. "sudo dmesg | grep ...") This results in the error message "dmesg: read kernel buffer failed: Operation not permitted" and causes missing output in "ALSA/HDA dmesg" Issue URL : https://github.com/alsa-project/alsa-utils/issues/146 Repository URL: https://github.com/alsa-project/alsa-utils
