Referring to fig. 1, fig. 1 is a schematic view of a scene of a method for setting audio hardware parameters according to an embodiment of the present invention; in fig. 1, the audio device is a speaker as an example, the terminal 102 is a computer, and assuming that the audio device connected to the computer at the last time is the speaker 1, and the audio hardware parameter set by the user 101 for the speaker 1 is a, the audio hardware parameter stored in the configurable structure at this time is a. When the audio device is replaced by the loudspeaker 2, the audio hardware parameter set by the user 101 for the loudspeaker 2 is B, and at this time, the computer updates the variable value of the configurable structure from a to B by calling the first callback function. When a user needs to use the speaker 2 to perform audio playing, that is, the computer receives an audio operation instruction (assumed to be an audio playing instruction) for the speaker 2, the computer refreshes the current audio hardware parameter (the audio hardware parameter before refreshing is still a) of the speaker 2 according to the updated configurable structural body (at this time, the audio hardware parameter in the configurable structural body is B), so that the speaker 2 executes an operation corresponding to the audio operation instruction according to the audio hardware parameter (B), that is, an audio playing operation.

Fig. 2 is a schematic flow chart of a method for setting audio hardware parameters according to an embodiment of the present invention; the audio hardware parameter setting method comprises the following steps:
201. acquiring audio hardware parameters set by a user aiming at target audio equipment, wherein the audio hardware parameters are set parameters of an audio bus;
specifically, the audio hardware parameters include a clock of the audio bus, a frame synchronization timing mode, an operation mode, and the like. The audio bus includes I2S bus and PCM bus, I2S is commonly referred to as Inter-IC Sound, Integrated Interchip Sound, or IIS for short. On the I2S bus, only one master and a sending device can exist at the same time. The master device may be a transmitting device, a receiving device, or other control device that coordinates the transmitting device and the receiving device. In the I2S system, the devices that provide the clocks (SCK and WS) are the master devices. I2S is divided into three different modes of operation, standard I2S mode, left alignment mode and right alignment mode.
Pcm (pulse Code modulation) is a method of digitizing an analog signal by sampling at equal time intervals (i.e., sampling rate clock cycles). PCM digital audio interfaces, i.e. interfaces where audio data transmitted over the interface is sampled by means of PCM. The frame synchronization timing patterns include a long frame synchronization pattern and a short frame synchronization pattern. The operation modes of the PCM BUS comprise three modes of ST-BUS, GCI and McBSP.
202. Calling a first callback function, updating the variable value in the configurable structure according to the set audio hardware parameter, wherein the configurable structure is used for storing the audio hardware parameter of the audio equipment, and the first callback function is used for realizing the parameter setting of the configurable structure through the name of the audio hardware parameter;
specifically, the first callback function is utilized to modify the specific numerical value of the corresponding audio hardware parameter in the configurable structure according to the name of the audio hardware parameter.
203. And responding to the audio operation instruction of the target audio equipment, refreshing the current audio hardware parameter of the target audio equipment according to the updated configurable structural body, and executing the operation corresponding to the audio operation instruction.
Specifically, in order to avoid POP sound (POP sound is a POP sound generated by transient impact caused by various operations at the moment of power-on and power-off of an audio device and after power-on is stable), after receiving an audio operation instruction of a user for a target audio device, the audio hardware parameter of the target audio device is refreshed, and an operation corresponding to the audio operation instruction is executed. The audio operation instruction includes an audio playing instruction and an audio obtaining instruction (e.g., recording, etc.).
Therefore, the method of the embodiment of the invention can dynamically modify the audio hardware coefficient of the target audio equipment, is simple and convenient to modify and operate, and effectively improves the user experience. In addition, the workload of audio driver software debugging can be reduced to a great extent, and the compatibility and the portability of the audio driver software version are improved.
In the embodiment of the invention, a structural body for storing audio hardware parameters is designed, namely a configurable structural body is designed for storing all possible audio hardware parameters of audio equipment. Wherein, different parameter variables in the configurable structure body represent different hardware parameters of the audio bus respectively, the audio hardware parameters take a clock, a frame synchronization timing mode and an operation mode as examples, and the configurable structure body at this time may be:
in one possible embodiment, before performing step 201, the method further comprises:
s1, obtaining configuration parameters of the audio equipment in the equipment tree;
specifically, configuration parameters about the audio device in a device tree of the terminal are obtained. The configuration parameters in the device tree may be configuration parameters of any audio device, and are not particularly limited.
And S2, initializing and filling each member variable in the configurable structural body according to the configuration parameters of the audio equipment in the equipment tree.
Specifically, in the drive loading stage, the values of the member variables in the corresponding structure body are filled by reading the configuration items in the equipment tree, so that the normal use of the default configuration of the equipment tree is ensured, and the normal initialization state is ensured.
Further, when initializing the audio driver software, a first callback function (put function) and a second callback function (get function) of each audio hardware parameter in the configurable structure need to be registered, so that the upper layer reads the current audio hardware parameter of the audio device by using the name of the audio hardware parameter, or sets a variable value in the configurable structure by using the name of the audio hardware parameter. For example, an snd _ dai _ new structure is defined, which is used to register a callback function of each audio hardware parameter, and a get function and a put function for the user layer are implemented in each callback function, such as:
registering a callback function of each audio hardware parameter, wherein the callback function is used for reading or setting the audio hardware parameter by the upper layer through the name:
static const struct snd_dai_new dai_params_config[]{
{.name＝“AUX_PCM Clock”,.get＝dai_params_clock_get,.put＝
dai_params_clocks_put},
…
}。
in addition, in the audio driver software, different kcontrol controls are registered according to the arrangement of the snd _ dai _ new structure, and the generated controls are registered for the use of the user layer setting parameters.
In one possible embodiment, step 203 comprises:
2031. responding to the audio operation instruction, and calling a second callback function to acquire the current audio hardware parameter of the target audio equipment, wherein the second callback function is used for reading the audio hardware parameter through the name of the audio hardware parameter;
specifically, after receiving the audio operation instruction, the terminal calls the second callback function to obtain specific values of all current audio hardware parameters of the target audio device.
2032. When the updated audio hardware parameters of the configurable structure body are different from the current audio hardware parameters, calling a parameter refreshing function to refresh the audio hardware parameters of the target audio equipment and executing the operation corresponding to the audio operation instruction;
specifically, when the updated audio hardware parameter in the configurable structure is different from the current audio hardware parameter obtained in step 2031, it indicates that the audio hardware parameter of the target audio device needs to be refreshed, at this time, a parameter refresh function is called to refresh the audio hardware parameter of the target audio device, the audio hardware parameter of the target audio device is refreshed to the audio hardware parameter of the configurable structure, and then the operation corresponding to the audio operation instruction is executed. The parameter refresh function may be a flush function, or may be another function. Furthermore, the audio hardware parameters in the updated configurable structural body at the moment can be saved as power-down backup data; and outputting parameter setting success information to enable the user to know the parameter setting result. The power-fail backup data can be stored in the nonvolatile storage medium, so that the data can still be stored after power failure.
The successful parameter setting information may be output by directly displaying the information on the terminal or sending a message such as a short message, a QQ message or a WeChat message to a predetermined user terminal.
2033. When the updated audio hardware parameters of the configurable structure body are the same as the current audio hardware parameters, parameter setting success information is output, and operation corresponding to the audio operation instruction is executed.
Specifically, the output mode of the successful parameter setting information is the same as that in step 2032, and is not described again.
Specifically, 2031, 2032 and 2033 are only used for distinguishing different steps, and the order of execution of these steps is not limited.
Therefore, in the parameter modification process, not only can the judgment on whether the parameter is updated be carried out, but also dynamic modification can be realized.
In a possible embodiment, since the audio hardware parameters stored in power down are provided, in order to avoid pop sound caused by repeated setting, user experience is optimized, and after power on, after the audio hardware parameters set by a user are obtained, the method further includes:
s3, acquiring power-down backup data;
specifically, as can be seen with reference to the description of step 2032, the power-down backup data stores audio hardware parameters set by a user for refreshing, and when the parameters are stored, the corresponding relationship between the time and the audio hardware parameters may be stored, for example, in a table form. Further, only the audio hardware parameters with the latest time can be reserved, that is, in the manner of covering storage, when there is a new audio hardware parameter needing to be stored, the audio hardware parameters with the older time are covered. It is also possible to save a fixed time interval or a preset number of audio hardware parameters, for example, only audio hardware parameter data with a time interval within 2 days or 5 days (or other time intervals) is reserved. Or only 3 or 5 (or other numbers) audio hardware parameters are reserved, and the setting can be carried out according to the needs.
After the audio hardware parameters set by the user are obtained, data recovery can be performed from a backup area (namely, a nonvolatile storage medium) of the terminal, and the latest audio hardware parameters at the power failure time in the power failure backup data are obtained.
S4, when the audio hardware parameter at the latest power failure moment in the power failure backup data is the same as the set audio hardware parameter, outputting parameter setting success information;
specifically, the fact that the audio hardware parameter at the latest power failure time is the same as the set audio hardware parameter indicates that the current audio hardware parameter of the audio device is the same as the audio hardware parameter that the user wants to set, and the configurable structural body does not need to be updated, and at this time, the parameter setting success information is output. When an audio operation instruction for a target audio device is received, an operation corresponding to the audio operation instruction may be directly performed.
And S5, when the audio hardware parameter at the latest power failure moment is different from the set audio hardware parameter, executing and calling a first callback function, and updating the variable quantity value in the configurable structural body according to the set audio hardware parameter.
Specifically, when the audio hardware parameter at the latest power down time is different from the set audio hardware parameter, it indicates that the current audio hardware parameter of the audio device is different from the audio hardware parameter that the user wants to set, and at this time, the configurable structural body needs to be updated, that is, step 202 and step 203 are executed.
When the configurable structure body is updated, the audio hardware parameters set by a user can be transferred to the first callback function by calling the amix function, so that the first callback function correspondingly modifies the data of the configurable structure body according to the name of the audio hardware parameters, and the configurable structure body is updated.
Likewise, S3, S4, and S5 in the foregoing description are only for distinguishing different steps, and the execution order of the steps is not limited.
In one possible embodiment, when audio hardware parameters set by a user are acquired, information input by the user can be received through a preset interface; in addition, a historical data selection window can be provided, historical data displayed in the window are power-down backup data (more than one data), a user can directly select audio hardware parameters to be set by clicking, manual input is not needed, and user experience is improved.
