我是 Linux 用户并且已经安装了新的蓝宝石 PULSE Radeon RX 580 8GB在我的机器上，卡的 HDMI 输出出现音频失真。 Linux 内核 AMDGPU 视频驱动程序似乎可以按照视频的预期工作，但在两个完全独立的系统上新安装的各种 Linux 发行版（Fedora、Debian、Ubuntu、Arch Linux）中仍然存在一个奇怪的音频音调问题（详细信息如下）。
另一位用户在评论中指出，他可以在以下显卡上确认相同的问题：
- XFX Radeon RX 590 Fatboy 核心版 8GB
- XFX Radeon RX 570 RS XXX 版
观察结果
通过 HDMI 端口输出声音时，全部音频被调高了音调，听起来像《阿尔文和花栗鼠》的动画片。根据应用程序，播放速度会提高（大约 2 倍）以匹配加速的音频，或者播放速度为正常 (1 倍) 并且音频会变得断断续续（快速断断续续）以匹配它。
我测试了来自许多不同应用程序的音频，除了快速播放以匹配音频与断断续续的音频以匹配播放如上所述，加速的音频问题在所有这些中都持续存在。这里有一些例子：
- 系统声音：播放大约。 2倍速
- 火狐浏览器（网站包括 YouTube、Facebook 和雅虎新闻）：视频播放时间约为2 倍速度以匹配音频
- 侏儒视频（音频和视频文件）：播放大约。 2倍速度；如果有视频，它会加速以匹配音频
- VLC 媒体播放器（音频和视频文件）：以正常 (1x) 速度播放且音频断断续续
- 战场4（在 Wine 下运行，通过 Lutris 安装）：游戏以正常 (1x) 速度进行，音频以大约 1 倍的速度播放。 2倍速
- GNOME 设置扬声器测试实用程序（在“设置>>声音>>输出”下）：播放大约。 2倍速
我尝试过的故障排除步骤
在完全不同的系统上安装显卡并执行各种 Linux 发行版的全新安装。结果：两个系统和所有发行版上都存在相同的音频问题。
断开 HDMI 电缆并通过 DisplayPort 连接显示器，然后通过 USB 耳机测试声音输出。结果：没有音高转换问题，但音频出现裂纹/模糊/失真，其严重程度从间歇性到严重（无法识别的音频）不等。
禁用基于定时器的音频调度通过编辑
/etc/pulse/default.pa按照描述这里。结果：没有明显的效果（然后我将文件恢复到原始状态）。去除
alsa-plugins-pulseaudio按照说明这里查看问题是否出在 PulseAudio 上。结果：没有明显的效果（然后我重新安装了该软件包）。按照 @dirkt 在评论中给出的建议，我使用不同的比特率播放了一个已知的 WAV 文件
aplay -t raw -r [bitrate] -f [sample format] [file name]，并通过强制以文件实际比特率的一半播放（例如，对于 22050 Hz PCM，我指定-r 11025）。我不确定这是否是一个非常有用的结果，因为本质上该文件是以半速播放的，并且由于音高转换问题导致速度增加了 2 倍，因此听起来才正常。
我还对这个系统做了很多研究（在我的中等知识水平），但没有什么对我来说很突出。我广泛参考了man pulse-cli-syntax使用pacmd但未能找到解决方案。无奈之下，我给一位朋友打了电话，他是一位 Linux 专家用户，经常与 Linux 中的硬件进行交互，这是他工作的一部分。他慷慨地花了10个小时调查此事，结果感到困惑。我想我无法列出他尝试过的所有事情，但他主要使用 Arch Linux 从头开始设置声音设备。他的大部分实验仅涉及使用 ALSA（无 PulseAudio）来最大限度地减少“移动部件”的数量，尽管他也尝试了使用 PulseAudio 进行一些操作。
系统信息

请注意，在aplay -l上面的输出中，设备信息相当通用。在alsamixer我只看到Card: PulseAudio和Chip: PulseAudio，我认为这意味着 PulseAudio 正在处理所有硬件细节。同样在上面的输出中，我预计会看到四个devices，因为该显卡有两个 HDMI 端口和两个 DisplayPort 端口，但实际上有六个；我不知道额外的两个 HDMI 设备是什么。
