使用 alsa/amixer(/jack?)、SB Audigy2 卡在 Debian 上录制和监控 Line In

注意！我放弃解决这个问题（至少是暂时的）安装了另一个 Audigy 2 - 带有外部单元。3 个输入中有 2 个可以工作，但它们的名称不正确并且级别有问题。

我在驱动程序页面的评论中读到过类似的问题。设置正确的模块参数可能会有所帮助 - 但很难选择正确的参数，而且我还没有找到相关的最新 alsa 文档。

可以一个一个地尝试，但是因为我购买了二手 TASCAM USB 音频接口，所以现在就这样做。

我无法配置 Audigy2 卡以使用 Line In 进行监控和录制

以前我只使用内置声音（HDA Intel），配置它相对简单：有一个“输入源”控制，可以在其中选择线路、带有 cvolume 的捕获控制 - 用于录制，以及带有 pvolume 功能的线路控制 - 用于监控。

现在我正在尝试使用专用卡：SB Audigy2 Platinum。

我正在使用 Debian（嗯，Devuan），并希望尽可能保持其简单（即命令行，没有 PulseAudio 等）

因此，对于 amixer/alsamixer 中的 Audigy2： - 没有输入源混音器控制 - 只有这个“线路”控制，仅具有捕获功能（cvolume、cswitch、cswitch-joined）

线路已打开，但没有任何内容通过它录制。有一个“高清源捕获”控件，但没有“线路”选项，因此它可能无关紧要。

我不知道该如何监控 Line In。我想也许可以通过使用 Jack 将 Line In 路由到播放？

jack_lsp 返回：

system:capture_1
system:capture_2
system:playback_1
system:playback_2

所以我尝试了这个：

​jack_connect system:capture_1 system:playback_1

无济于事（虽然不是很确定，因为录音也不起作用）（抱歉，如果这个命令没有意义 - 关于 Jack 的维基百科看起来更像是笔记的集合，而不是详细的规格/参考，如果有人可以推荐一个好的，那就太好了）

为了测试目的，我尝试在 Reaper 中录制（使用内置卡时可以正常录制）。

它拒绝通过 ALSA 直接与 Audigy2 一起工作（“打开音频硬件时出错：ALSA：设置输入设备周期计数时出错”），但在使用 JACK 时可以工作。

或者确切地说，播放可以，但录音（或至少从 LINE IN 录音）不可以。

当选择 system:capture_1 作为音轨的输入时，级别不会显示任何内容。虽然录制播放（使用 PCM 捕获控制）确实有效。

答案1

部分答案：

首先尝试让一切在 ALSA 中运行；Jack 只是 ALSA 的一个附加层。

您可以使用

arecord -L

显示所有 ALSA 输入设备；根据您的 Jack 信息，您的 Audigy 可能有两个（代表硬件中的两个 ADC 转换器）。

您可以使用

sox -t alsa plughw:0,0 -n

获取输入设备的连续级别显示。plughw:0,0表示卡 0、设备 0，带有默认 ALSA 插件（采样率转换器等）。确切值取决于的结果arecord -L。

因此，请对每个输入设备尝试此操作，同时alsamixer在另一个终端中打开。然后，取消静音每一个混音器（它应该显示OO而不是MM）可以以某种方式与声音输入相关，移动到某个中等水平，看看会发生什么，以及您是否可以弄清楚它的作用。

根据我的经验，这是“无法录制声音”的首要问题 - 某些 ALSA 混音器已关闭或级别错误。

我尝试在 Google 上搜索一些有关 Audigy 2 硬件的信息，但没有找到任何信息，所以如果你碰巧有一张混音器连接图，那也会有所帮助。

“打开音频硬件时出错：ALSA：设置输入设备周期计数错误”）

无关，假设“设备周期数”是采样率，您要么没有使用 ALSA 采样率转换器插件，要么 Reaper 有其他与硬件不相符的地方。但我对 Reaper 不熟悉。

但当使用 JACK 时可以工作。

正如我所写的，首先尝试不使用杰克。

播放某些内容时确实会显示某些内容

有混频器将声音输出的回环添加到声音输入。尝试使用上述方法识别并禁用它们。aplay如果 Reaper 不工作，您可以使用 WAV 文件。

答案2

PCI 卡背面的 Line-In 端口无法单独录制，这是硬件限制 — 请参阅“如何在 Audigy 和 Audigy 2 上录制”部分emu10k1 驱动程序页面（整个页面都值得一读）。

正如所示，可以记录所有模拟源的模拟混合。

一些 Audigy 变体具有5¼”接线盒带有额外的输入端口；这些端口可以作为捕获端口正常工作，在与 Jack 交互时应优先使用。您的帖子没有表明您是否拥有一个；如果有，我建议您忘记 PCI 卡的后端口用于捕获。

附注：我曾经拥有这款卡的一个变体（Audigy2 ZS），带有接线盒，我很喜欢它，但不幸的是，多年来出现了爆音和噼啪声；不确定是否所有的 Audigy2 都受到影响，但要知道，如果你的卡也遇到这种情况，焊接电解电容器可能会保存您的卡。
