layer, decided to use MIC input or line input. This greatly simplifies the difficulty of code modification, after all, it is easier than directly modifying the Linux Kernel Alsa.For the use of amixer, you first need to understand what parameters you want to set, and then it is possible to understand, how to configure the corresponding value, overall, relative to Alsamixer, is a bit cumbersome, the following brief introduction of its specific usage:1.
, amixer can modify the register value of the audio chip from the application layer and decide to use mic input or line input. This greatly simplifies the difficulty of code modification. After all, it is easier to directly modify Linux kernel ALSA. To use amixer, you must first understand the parameters you want to set before you can understand how to configure the corresponding values. In general, compared with alsamixer, it is a bit cumbersome. The

In general, Black-and-white photographs can be more historical and stale than color photographs. If you don't think of it in black and white at the time of filming, then we can use Photoshop to convert color photos into Black-and-white photos. There are a lot of ways to convert, below we have a picture of a little Lori to explore the production of black and white
