我正在运行 Debian Stable Linux，它运行良好。我已经使用beep命令安装了软件包apt install beep。没有错误。但是，命令beep不起作用。以下是错误：
$ beep
beep: Error: Could not open any device
$ BEEP_LOG_LEVEL=999 beep
beep-log: Verbose: log_constructor
beep-log: Verbose: beep_driver_console_constructor
beep-log: Verbose: beep_drivers_register 0x564bb79ad6a0 (console)

beep: Verbose: b-lib: could not stat(2) /dev/vc/0: No such file or directory
beep: Error: Could not open any device
网上有很多页面讨论这个问题，尽管大多数都是针对 Ubuntu 的。然而，他们的解决方案（包括）sudo modprobe pcspkr并sudo usermod -aG input iuser没有纠正错误。
问题出在哪里？如何解决？
