that there are five directions for ction. If direction is empty, playback and capture are bidirectional.
A standard kcontrol such as soc_double ("PCM playback volume", ac97_phone, 8, 0, 31, 1 ), where "PCM" is the source, "playback" is the direction, "volume" is the function-volume adjustment, this kcontrol is to adjust the volume of the playing PCM.
For example, soc_single ("mic switch", ac97_cd, 15, 1, 1 ), where "

Today in the project, you need to listen to the headset Plug and play, so I wrote the following a small demo, the headset monitoring events to verify. Look directly at the code PackageCom.example.alert; ImportAndroid.content.BroadcastReceiver; ImportAndroid.content.Context; Importandroid.content.Intent; ImportAndroid.util.Log;ImportAndroid.widget.Toast; Public classHeadsetplugreceiverextendsBroadcastreceiver {@Override Public voidOnReceive (Context context, Intent Intent) {//TODO auto-generated
Solution one, if chatting in QQ, regardless of the increase in mic volume, the other side hears the sound is always very small, this time, may wish to turn on the stereo mix function, the method is right clicks the taskbar small horn, chooses "The recording equipment", then right clicks the window blank place, selects "Displays the disabled device", then will appear " Stereo mixer icon. Right-click the stereo mixer icon, select Enable (Figure 1), and
Introduction of regular expressions
Translation: Northtibet
Some beginners are not very familiar with regular expressions, it is necessary to make a brief review here. If you're a regular expression master, you don't have to look at this part.
A regular expression is a string that describes a set of strings. For example, the regular expression "mic*" describes all strings that contain "Mic" followed by 0

With GSSAPI key Exchange servers does not need SSH host keys when being accessed by clients with valid credentials.If you is not using GSSAPI as a authentication mecanism, it might is causing this connection delay.In my particular case, I-ran ssh-v myserver to find-out it's hanging whilst attempting to authenticate WI Th GSSAPI, with the slow sections looking like:... Debug2:key:/home/user/.ssh/id_rsa (0xb961d7a8) Debug2:key:/home/user/.ssh/id_dsa ((nil)) Debug2:key:/home/ USER/.S
channel will basically only be occupied by attackers. Therefore, this attack can severely reduce the communication efficiency of the nodes in the compromised WLAN. In addition, the integrity check value in 802.11 (ICV) is designed to ensure that the data in the transmission is not due to noise and other physical factors caused by the message error, so a relatively simple and efficient CRC algorithm. But an attacker could modify the ICV to match a tampered message, without any security features.
information coefficient (MIC) are often related to the measurement variables of specific function types (such as linear, exponential, periodic function), and the maximum information coefficient can measure the correlation of any function form, so the maximum information coefficient has generality For data of different function forms with equal maximum information coefficients, the maximum information coefficient is equal when the same noise is given

GSSAPI (Generic Security Services application Programming Interface) is a set of common network secure system interfaces similar to Kerberos 5. This interface is an encapsulation of various client server security mechanisms to eliminate the differences in security interfaces and reduce programming difficulty. But the interface is problematic when the target machine has no domain resolution

Embed sub-objects in our objects
There are several rules for sub-objects. A child object is treated as a "Base Object", and its vtable pointer must be the first real member of our object. For example, let's use our imicin sub-object as the base object, so that we define our object (we call it iaudiocard), embed the imicin sub-object to the first position, and then embed other sub-objects:
Typedef struct {imicin mic; // Our imicin (base) Sub-objec
.
Perform analysis:
Recording: the mic is sent to codec and converted to a digital signal through the ADC. It is stored in the first-in-first-out (FIFO) of the CPU through the ac97 interface in pending 2, and transferred to the memory through the DMA Interface in pending 1, the snd_pcm_readi interface in alsa_lib to be continued 3 is passed to the recording software and encoded to form an audio file.

No sound or no light microphone ~? It is estimated that there is a problem with the front-end audio-frequency line connection method of the chassis. You can put a power first to restore the factory settings.
Common Front-frequency line connection method
At present, the front-end audio terminals of the jinhetian chassis and the front-end audio plug-in of the motherboard are generally connected as follows:
