我开始在windows 10中使用C++开发一个简单的吉他活套。我并不确定是否应该使用API函数来实现服务器的启动和关闭，但是由于我发现启动服务器和使用单个命令设置参数都很方便，所以我为它创建了一个脚本。

代码语言：javascript
运行
复制
ECHO HELLO JACK!
cd C:\Program Files\JACK2
jackd.exe -S -X winmme -v -r -t10000 -dportaudio -d"ASIO::ASIO4ALL v2" -r44100 -p512
:: /jackd.exe -S -X winmme -v -t10000 -dportaudio -d"ASIO::Komplete Audio 6" -r44100 -p512  this is for when audio interface is selected. Not used in this script.
PAUSE

在开发过程中，测试我的代码的方法是编译它，在开始运行它之前，我必须先启动服务器，在大多数情况下，我更喜欢使用qjackctl来完成它。但是，这种方式很容易出错，因为已经发生了许多问题，特别是当“关闭服务器的适当方法”出现时。例如，通过qjackctl停止服务器强制我的运行程序退出正常，但是关闭我的运行程序而没有停止服务器会破坏千斤顶音频行为，即。有时qjackctl挂起，崩溃，即使我重新启动计算机，或者重新安装jack也解决不了问题。

日志窗口消息是以下…

尽管它似乎已经启动，但会出现一个qjackctl通知窗口，其中包含以下消息：

Could not connect to Jack server as client.
-Overall operation failed.
-Unable to connect to server.
Please check the messages window for more info.

在不按“取消”的情况下，我每两次就能运行一次程序，就像服务器正常工作一样，而按下“取消”会使服务器停止运行。但在两次反复的尝试中只有一次。至于代码，我还测试了jack音频文档中的现成示例，以检查是否会注意到任何差异，但没有发现任何差异。

我真的不知道如何调试它，因为在互联网上找到的大多数解决方案都是关于Linux环境的，除此之外，我发现我的实现实践是很传统的，而且我非常肯定，我可能不得不使用API命令，而不是搜索现成的脚本解决方案。但是，现在首先要调试服务器。

因此，如果有人知道我应该如何使jack服务器再次正常运行，那就太好了！

编辑在发布问题10分钟后，我成功地调试了这个问题，但是我将帖子保留在打开状态，以帮助其他面临类似问题的人。对我有效的解决方案是运行由C++示例修改的以下server_control代码：

代码语言：javascript
运行
复制
#include <iostream>
#include <jack/jack.h>
#include <jack/types.h>
#include <jack/control.h>

static jackctl_driver_t * jackctl_server_get_driver(jackctl_server_t *server, const char *driver_name)
{
    const JSList * node_ptr = jackctl_server_get_drivers_list(server);

    while (node_ptr) {
        if (strcmp(jackctl_driver_get_name((jackctl_driver_t *)node_ptr->data), driver_name) == 0) {
            return (jackctl_driver_t *)node_ptr->data;
        }
        node_ptr = jack_slist_next(node_ptr);
    }

    return NULL;
}

int main(int argc, char *argv[])
{
    jackctl_server_t * server;
    const char* driver_name = "portaudio";//You could probably change the driver name accordingly 


    server = jackctl_server_create2(NULL, NULL, NULL);

    jackctl_server_open(server, jackctl_server_get_driver(server, driver_name));
    jackctl_server_start(server);

    jackctl_server_stop(server);
    jackctl_server_close(server);
    jackctl_server_destroy(server);
    return 0;
}

您的窗口音频比特率可能需要匹配的杰克是什么要求。否则，某些东西会在独占模式下消耗您的界面。
