11.2 Building and installing the driver manually
This method works for any Linux system, but it is necessary to apply it every time the kernel is
updated, as it doesn't use any package manager to automatically rebuild the driver.
Requirements:
The kernel headers for the kernel version(s) you need
Git
Make and a C compiler such as gcc
Please refer to your distribution's documentation to install these requirements.
1. Get the source code
2. Compile the driver: Go into the src/ directory, and compile the driver by simply running make
to create the file: snd-alpx.ko and snd-pcm-dmaengine.ko depending on your current kernel's
configuration
3. Install and load the driver: The compilation has generated a kernel module: snd-alpx.ko.
4. Copy this/these module(s) to the kernel's module directory:
5. Run "sudo depmod -a"
6. Run sudo modprobe snd-alpx
7. Then run lsmod | grep snd to check installation of the driver
8. Run aplay -l or L to list the devices
9. Launch alsamixer
