Audacity 不再适用于 pulseaudio

  • 772

更新：今天的升级alsa-lib-1.1.7-2解决了这个问题。(2018-11-23)

Arch Linux，最新。像往常一样，-Syu升级再次破坏了一切。这一次是大胆。通常大胆，任何其他播放/录制应用程序都会出现pauvcontrol- 不再是大胆。我可以使用pauvcontrolaudacity 来选择我想从中录制或播放音频的接收器和源 - 不再是。

在大胆的偏好中，它只ALSA在顶部下拉列表中说，我不确定这是否应该是这样的，或者它PulseAudio之前是否说过。播放选项卡中甚至没有我的所有设备。录制设备选择也是如此，但我需要录制的环回设备在那里，所以可以工作。

喜好

但现在我也想从 Audacity 播放声音，但它不再起作用了。它没有列出我的 USB 播放设备，当我将其设置为时，sysdefault我得到一个错误。

$ pulseaudio -v
pulseaudio 12.2

$ audacity --version

不确定这些警告是否意味着什么，它不会打印版本。

即使我不确定这些错误是否是由于 ALSA 造成的，并且可能与 PulseAudio 问题完全无关。

  1. Best Answer

    从论坛我发现了这个错误。这是最新 (1.1.7) 版本的问题alsa-lib。现在将其降级到以前的版本应该可以解决该问题：

    pacman -U /var/cache/pacman/pkg/alsa-lib-1.1.6-1-x86_64.pkg.tar.xz

  2. 我正在运行 1.1.8-1 的 alsalibs 并且遇到了类似的问题。开始大胆将我的输出更改为内部扬声器。我得到它的工作alsactl restore，然后pulseaudio -k，但它是wonkey。VLC 和 Audacity 似乎不能同时使用输出。
