多用户使用问题

你好，我在ubuntu22.04下，使用 `sudo ekho "hello"` 提示如下错误 ``` pa_simple_new() failed: Connection refused pa_sample_spec(format=3,rate=22050,channels=) Assertion 'p' failed at ../src/pulse/simple.c:273, function pa_simple_write(). Aborting. ``` 或者我在系统自启一个程序，程序里面调用了system("/usr/local/bin/ekho hello");函数，会抢占了正常系统下的音频设备。导致音频设备不用使用。 请问有什么方法使多个用户使用吗？自启动的程序调用ekho也可以用的方法。
