我安装了专有的 Nvidia 384.90 驱动程序,它可以看到两张卡。第一张卡通过 HDMI 连接到三星“智能”显示器(不确定型号)。有一个 JVL 壁式扬声器通过光纤电缆插入三星。直到 Ubuntu 17.04,声音都通过 HDMI 工作。HDMI 声音选项仍然显示在声音、pavucontrol 和 alsamixer 中。
当此电脑启动 Windows 时,声音仍然正常工作。
目前,17.10(和 17.04)上的声音非常不连贯、断断续续,甚至听不清单词。更改延迟有帮助,但不能解决问题。奇怪的是:如果我在 PAVUCONTROL 中减少或增加延迟,在重置延迟设置(无论方向如何)时,我会听到正常的声音,但只要我停止更改并释放设置控件(用鼠标设置),不连贯的声音就会再次出现。
任何想法,将不胜感激。
底部输出以下命令:
