Ii. Sound Card drive
For security considerations, Linux applications cannot directly operate hardware devices such as sound cards, but must use the driver provided by the kernel. The essence of audio programming in Linux is to use the driver to complete various operations on the sound card. Hardware control involves the operation of each bit in the register. Gener

ALSA is not a new thing that has just emerged recently. It has actually been developing for many years. However, it has not become a proper replacement for OSS names until it is in kernel 2.6. ALSA provides not only a few sound card drivers, but a

Dear friends, after a day of time, Xiao Xiao came again.Last time we talked about the history of Linux, let's talk about the installation of Linux systems today.Because Xiao Xiao's computer monitor is 4K, there is no way to find the normal display, so I borrowed our teaching pictures to chat about the installation of the system.Three elements of the installation system: Boot disk, system disk, installation disk.Here we use virtual machine to do demonstration, drive.1) start the New Virtual Machi

It is so easy to create, delete, and open databases. Now it is time to use OSS.
