Linux 在RHEL 6 x64中配置网络音频系统[NAS]时出错
我尝试通过两种方法在RHEL 6中设置NAS（网络音频系统）： 首先，通过RPM安装Linux 在RHEL 6 x64中配置网络音频系统[NAS]时出错,linux,qt,audio,redhat,Linux,Qt,Audio,Redhat,我尝试通过两种方法在RHEL 6中设置NAS（网络音频系统）： 首先，通过RPM安装 [root@localhost ~]# rpm -Uvh nas-1.9.2-1.el6.x86_64.rpm nas-libs-1.9.2-1.el6.x86_64.rpm 它已安装，但在/etc/init.d/目录中找不到该服务。 仅创建/etc/nas/nasd.conf文件。如果我运行命令 [root@localhost ~]# nasd Network Audio System Release 1.
[root@localhost ~]# rpm -Uvh nas-1.9.2-1.el6.x86_64.rpm nas-libs-1.9.2-1.el6.x86_64.rpm

Fatal server error:

请帮助我正确安装，因为我想为基于qt的应用程序启用音频，并且qt使用NAS实现其音频功能 NAS非常努力，但未能成功解决我的问题 然后我用声子库来解决声音问题
谢谢你帮了我！：） 好的。好吧，已经有一段时间了，但是 您没有足够的烫发来打开底层套接字 me@dev$strace-o./nasd.txt nasd-aa-config./nasd.conf
