我做的播放器为什么要一直动主音量里面的波形才能听到声音？
如题：我做的播放器不知道为什么要一直动主音量里面的波形才能听到声音？歌是一直在放的，但是就是听不到声音，一定要一直动那个主音量里面的波形才能听到。。。。我是新手，啥都不会，请大家帮帮忙好吗？如果需要查看源程序才能知道的话，加QQ：150972046谢谢~我今晚就要用到了，请大家帮帮忙哦~ --------------------编程问答-------------------- 让别人猜谜？ --------------------编程问答-------------------- 程序在此，请大家帮忙看看好吗？
还有我不会不知道怎么匹配那个歌词和MP3的文件名

--------------------编程问答-------------------- 这么长，什么要一直动主音量里面的波形才能听到声音？不明白什么意思，贴个图看看 --------------------编程问答-------------------- 电脑桌面右下角那个声音喇叭，双击之后出来那个主音量的波形那一条进度条，要一直调那个値才可以听到声音~搞了很久都不知道是什么问题~ --------------------编程问答-------------------- 关注。。。。 --------------------编程问答-------------------- --------------------编程问答-------------------- 你既要用 sdleft.Value = Mp3Play1.GetVolumeLeft 显示声道的音量，
又用 Mp3Play1.SetVolume(sdleft.Value, sdright.Value) 设置音量。
两者相互之间循环影响。
