the best choice is to use the headset, that is, headset headphones, microphone combination. The headset is designed for voice communication, so the headset and microphone design is particularly suitable for voice communication, and the use of headset, both allows you to emp

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 e

stillIn non-mobile devices (such as PCs), the audio frequency is usually produced by a crystal oscillator, but in the design of smart phones, to avoid additional power consumption, board space, and frequency chip costs, the designer prefers to separate the frequency functions required by the HIFI audio from the existing frequency. Because the low power consumption and low noise lock loop (PLL) can be integrated into the hybrid signal chip at a relatively low cost, so today's chip manufacturers

Integrated smart phones must have PCM interfaces and independent I2S or ac'' 97 interfaces at the same time.

These days we have dramatically modified our ALSA audio driver and have a deeper understanding of the importance of mechanism and policy separation. To put it bluntly, Linux device drivers has gone through countless times, but ignores one sentence in the Introduction: differentiation mechanisms and policies are one of the best ideas behind UNIX design. "What features are required" is a mechanism, and "how to use these features" is a policy. More than a year ago, when I first took over audio driv

To connect to other mobile phones through Bluetooth, follow these steps:1. Click application on the standby page ].2. Click set ].3. Click [Bluetooth] and then click the slider below it. Green indicates that it is enabled.4. When this feature is enabled, the tablet automatically scans available devices and selects the device to be paired. Here, we use Galaxy J3 as an example. (Note: Make sure that the pairing device has Bluetooth enabled and is visible .)5. A Bluetooth pairing request will pop u

, Playandrecord is specifically designed for such a scene. Avaudiosessioncategorymultiroute: Imagine a DJ with the app, the phone attached to the HDMI to the speaker to play the current music, and then play the next song in the headset, this ordinary people do not understand the scene, this category can support multiple device input and output. Avaudiosessioncategoryaudioprocessing: Mainly used for audio format processing, generally can be use

IPhone7 How to charge while listening to music? 3 Ways to solve Method One: Purchase Airpods wireless Headset Airpods Wireless Headset Function We have this like advanced Bluetooth headset, one charge can be used for 5 hours, easy to achieve side charge, while using Airpods wireless headset listening to music.

When using a computer, people often use headphones to watch movies or play games, but there are often netizens asked how to do headphones, there are many netizens are not sound how to set the computer headset problems, computer problems caused by many aspects of the problem, today, the Shield security engineers to teach you how to solve the problem of headphones do not sound. Why the headphones don't sound? Headphones have nothing to do, of course, f

Users of the Mac believe that many have encountered the internal failure of the speaker, do not know that there is no careful user will find a Mac with the horn failure and the headphone hole will light up the red light, as shown in the following picture, that Mac headset Kong Liang red light is what reason? The following small series for everyone to bring Mac headset Kong Liang red light, At the same time

Recently I want to upgrade my TV, so I want to buy a 46 (47) TV. I have locked several models on the Internet. Today I went to Suning and Dazhong and Gome to see the actual results, I would like to share with you that everything is my subjective feeling and the feeling of a batch of prototypes I have seen. So only one reference is provided. Source of the test: 1. 720 p MKV format x264 embedded subtitle cartoon aptx Conan. 2. h264 1080 p Deep Blue 3, h

through CTRL sock and intr sock. Ioctl_connadd (req ); 2.2 btd_register_device_driver Btd_register_device_driver is used to register the device driver. Two devices registered using this function in bluez are input_headset_driver and input_hid_driver. Input-headset is related to Bluetooth headsets, and input-hid is used for normal hid devices. Next let's take a look at the input_hid_driver device. Input_hid_driver Static struct btd_device_driver input

Method One 1. First of all, we need to open the Win7 flagship computer's Start menu, and then click from the Start menu to enter the interface of the control Panel. 2. In the Open Control Panel interface, we click to enter to adjust the system volume (search sound) → speaker properties (point speakers will bounce out) → enhanced, after clicking, we will be the loudness of the uniform option tick. 3. After the setup is complete, we will find that before the

(L2CAP) is used to control multi-user connections and process packet segmentation and combination. This is a common choice for applications.· Service Discovery Protocol the Service Discovery Protocol (SDP) is used to locate and describe the services provided or available by bluetooth devices. The application is mainly used when it is set to communicate with another bluetooth device.· The Host Control Interface the Host Controller Interface (HCI) driver encapsulates high-level modules for commun

data from a music player to a headset or speaker.Due to the narrow bandwidth provided by bluetooth, audio data may need to be effectively compressed to ensure real-time playback at the receiving end.Currently, a2dp only defines point-to-point audio transmission, but does not define broadcast-based audio transmission, probably because of the speed.A2dp is based on the avdtp transmission protocol. avdtp specifies how the link is established. After the

The switching between the earphone and the Horn channel of wm9714 is controlled by the register software, which is a little different from the method of inserting the earphone in the TV to let the amplifier pull down and turn off the external sound directly. You can set the value of 0x1c in wm9714, where 0x00a0 and 0x1200 in the headset. In the circuit, the eint11 is fixed externally to a high level. The eint11 is lowered by inserting a
