Alsamixer is one of the Linux audio architecture ALSA tools used to configure the various parameters of audio.Alsamixer is based on the graphical interface under the text, can be through the keyboard keys, left and right keys, etc., it is convenient to set the required volume, switch switches (switches) and so on, is In the Ubuntu12.04 system configuration interface, the operation is very simple, here is the use of Ubuntu12.04 line-in function (to achieve stereo function):Sound playback output c

from the experience of porting Z5S 4.4 kernel and the official 4.4 audio configuration file, we should not add any Nubia features (of course, the headset detection must have been added ), however, the Nubia mentioned here is nothing more than the Z5Sn es325 audio conditioning chip, which has no effect on z5s. in the previous official audio configuration file snd_soc_msm_Taiko 4.2, you can find es325 configurations. the z5s 4.4 kernel I transplanted earlier also removed es325 related code!

If you still need a second MIC, you can insert it on other pages and tune it accordingly. (For example, if my second MIC is in blue, the MIC is adjusted in rear blue in, which is the same as the first

Recently, I want to take a good look at Echo elimination. I didn't know how to fix it. Now I am collecting data. I am dedicated to audio signal processing. Repost a post written by a netizenArticleIn the future, we will analyze the problems he encountered.

[Switch] ssh logon is slow. Solution: ssh logon Solution If you use an ssh client (such as putty) to connect to a Linux server, it may take 10-30 seconds to prompt you to enter the password. It seriously affects work efficiency. Logons are slow and the logon speed is normal after logon. There are two possible reasons for this situation:1. DNS reverse resolution Problems OpenSSH will verify the IP address when you log on. It uses reverse DNS to locate the host name based on the user's IP address,

Using an SSH client (such as: Putty) to connect to a Linux server may wait 10-30 seconds before prompting for a password. Serious impact on productivity. Login is slow, log on up after normal speed, there are two main possible reasons for this situation:1.

Some new users are not very familiar with regular expressions. it is necessary to make a brief review here. If you are a regular expression expert, you do not need to look at this part. A regular expression is a string that describes a string set. For example, the regular expression "Mic *" describes all strings that contain "Mic" followed by zero or multiple characters. This regular expression of Mickey, M

At the pin end of the motherboard, we just need to know the definition of each root cuttings pin, and it's good to connect the front audio. Let's look at the definition of each pin on the motherboard: 1--mic in/mic (Microphone input) 2--GND (grounded) 3--

Structure Design To refine the structure, we should first start with the overall layout. I advocate that the overall structure should be well planned, that is, the upper and lower shell stop lines, the screw column and the main buckle structure should be well done to complete these three steps, the mobile phone framework is built. then follow the order

say something like this without making such a joke. So is the front-end audio so difficult to connect? Let's take a look.From the current market, we can see that the sorting of the front audio plug-in has become a fixed standard (such ). From the figure, we can see that there are a total of 9 pre-audio pins, But they occupy a total of 10 pin positions, and 8th pins are left blank.It is a typical frontend audio line. In fact, the frontend audio only needs to be connected to seven wires, that is,
