HI 永红

耳机无声音的现象，在118281中跟踪，
扬声器没有声音的现象在此票跟踪，
根据日志分析，该问题发生时，
断开蓝牙时，回和中控申请焦点，此时焦点申请时，中控未回复消息，
导致焦点更新失败，出现问题。

下一步：
需要中控查看，是否接收到voice call焦点的申请，看看为什么没有回复副屏。

HI ALL

已经提供日志给中控，等待回复！

HI 天颖

根据中控的回复，该条信息，中控没有收到消息，
需要通信的模块继续调查为什么该条消息没有发到中控。

已复现并同时抓取中控副屏的日志，问题发生时间为1685503358077998678，经过分析，副屏有向中控发送信息的日志，并且无异常抛出，但是中控日志中未收到该日志，正在分析中，初步怀疑是网络问题，

Hi,卿山，网络可能存在丢包问题，怀疑是连续发送的情况下会出现丢包的情况，请把两个请求发送的时间加一个间隔再尝试，是否还有丢包的情况

HI 天颖

我尝试在三次请求中增加了延时，测试了7分钟，切换将近50次吧，该问题没再发生。
请确认丢包的实际原因，谢谢!

Hi,鹏飞
根据日志和试验分析，中控和副屏网络通信，可能出现丢包的情况，请帮忙分析一下，谢谢

这个票号可能就跟网卡驱动的模式有关，他们昨天晚上解决了，的重新测试看下

Hi 永红

该问题网卡驱动已经修复，请使用6月2日的版本验证是否还会发生，谢谢！

在上述测试步骤下，一会儿蓝牙耳机没声音、一会儿喇叭没声音

HI 鹏飞

丢包问题还存在，请分析该问题，谢谢！

结论：zk收到了切换焦点的信息，应是zk上层未进行处理。

试验：蓝牙处于释放状态，微信通话建立-正常，切到蓝牙-正常，释放蓝牙-无声音输出
