Advanced Linux Sound Architecture (ALSA) is a software framework and part of the Linux kernel that provides an application programming interface (API) for sound card device drivers. Some of the goals of the ALSA project at its inception were automatic configuration of sound-card hardware and graceful handling of multiple sound devices in a system.
alsamixer is a terminal user interface mixer program for the Advanced Linux Sound Architecture (ALSA) that is used to configure sound settings and adjust the volume. It uses ncurses to draw its user interface. [3] [4] It supports multiple sound cards with multiple devices.
ALSA or alsa can refer to: . Advanced Linux Sound Architecture, a Linux kernel component; Air Land Sea Application Center, an organization of the United States Department of Defense responsible for developing tactics and procedures
Advanced Linux Sound Architecture (ALSA) [445] SELinux security module ... The Linux 0.99 tar.bz2 archive grew from 426 ... Initial reboot support [493]
The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes , or to reboot a computer without corrupting the filesystem . [ 1 ]
The Linux API is composed out of the system call interface of the Linux kernel, the GNU C Library (by GNU), libcgroup, [1] libdrm, libalsa and libevdev [2] (by freedesktop.org). Linux API vs. POSIX API. The Linux API includes the kernel–user space API, which allows code in user space to access system resources and services of the Linux kernel ...
Bypassing a real reboot may leave devices in an unknown state, and the new kernel will have to recover from that. Support for allowing only signed kernels to be booted through kexec was merged into version 3.17 of the Linux kernel mainline, which was released on October 5, 2014. [3]
Loadable kernel modules in Linux are loaded (and unloaded) by the modprobe command. They are located in /lib/modules or /usr/lib/modules and have had the extension .ko ("kernel object") since version 2.6 (previous versions used the .o extension). [5] The lsmod command lists the loaded kernel modules.
