我正在运行 Ubuntu 10.04，并且有一个外部声卡：Phonic Firefly 302。
我已经连接了设备，安装了 Jackd，并添加了以下行：
@audio - rtprio 99
@audio - memlock 500000
@audio - nice -10 to /etc/security/limits.conf
注销，重新登录，
运行 qjackctl（准确地说是 sudo qjackctl），
运行设置并在驱动程序选项上选择“firewire”，按“开始”，这就是输出：

答案1
您可能需要将用户 ID 添加到音频和视频组，然后将新的 juju 堆栈 Firewire 驱动程序列入黑名单，才能使一切正常运行。音频的 Firewire 设备需要在 ffado 中的旧 Firewire 驱动程序上运行。检查您的卡是否被 ffado 驱动程序识别ffado-mixer，然后按照 Ubuntu 论坛中的各种主题使其工作。如果不是，请购买新设备或恢复到 Windows！
