如何使用的PulseAudio从音频输出重定向到麦克风输入？ [英] How to redirect from Audio Output to Mic Input using PulseAudio?
问题描述
我工作的Maemo操作/ MeeGo的和Maemo移动应用使用的PulseAudio。我想打一个MP3给调用者（并取消麦克风这样做的时候，并没有听来电者，一切都应该在后台完成），要做到这一点，我有音频输出从某个重定向（如果没有可能，所有）应用程序，伪造它作为一个输入，使手机的应用程序使用它。
I'm working on a mobile app for Maemo/MeeGo and Maemo uses PulseAudio. I want to play a mp3 to caller (and cancel the mic when doing it, and not to listen caller, everything should be done on background), to do this, I have to redirect Audio Output from a certain (if not possible, all) app, fake it as a Input and make Phone app use it.
在我的Ubuntu PC，我pavucontrol做到了。我创建了一个空水槽，然后：
On my Ubuntu PC, I did it with pavucontrol. I created a NULL sink, then:
Audio Output (from Amarok) --> to NULL Output
Skype Input <-- NULL Output
Skype Output --> NULL
和它的工作，Amarok的播放的音乐，这是流对Skype的，没有它打我，我没有听说过的所有过程什么。问题是;
一个）的Maemo没有pavucontrol。
二）即使它没有（或者，如果我打包），这不会是什么好，因为这是一个只有-GUI应用程序，我需要做的这一切东西的背景，没有任何用户输入。 （意思是：CLI或API）
And It worked, Amarok played the music and It was streaming to Skype, without playing it to me and I didn't hear anything about all process. Problem is; a) Maemo does not have pavucontrol. b) Even If it did (or if I package it) It wouldn't be any good since It's a only-GUI app and I have to do all of this stuff on background, without any user input. (mean: CLI or API)
在被问及这个Freenode上#pulseaudio和乐于助人的人说：这可以pretty多少可以通过PACTL或pacmd做的，你想要的命令是移动汇输入和移动源输出，但是你需要要知道设备和流索引。所以它看起来像pavucontrol仅仅是一个图形用户界面，PACTL和pacmd都是实打实的，最重要的是，他们是CLI应用程序。
Asked about this on Freenode #pulseaudio and a helpful guy said "It can pretty much be done via pactl or pacmd, the commands you want are move-sink-input and move-source-output, but you need to know device and stream indexes." So It looks like pavucontrol is just a GUI, pactl and pacmd are the real deal, and most importantly, they're CLI apps.
我真的很感谢他，但我不知道PACTL，pacmd什么，移动 - 汇输入或设备/流指标，所以我需要一个非常简单的手册页，或类似的应用程序的来源，一个班轮命令（二？命令的整个页面？只要给我他们！^^）或具有足够的耐心，这个东西给我解释一下。
I'm really thankful to him but I don't know anything about "pactl", "pacmd", "move-sink-input" or "device/stream indexes" so I need a very simplified manual page, or a source of similar app, a one-liner command (two? whole page of commands?, just give me them! ^^) or someone with enough patience to explain this stuff to me.
推荐答案
一个谷歌搜索PACTL或pacmd发现一堆有用的结果。
这里是PACTL其中也有一个链接到pacmd靠近页面末尾的手册页：
PACTL手册页
A Google search of "pactl or pacmd" found a bunch of useful results. Here is a man page for pactl which also has a link to pacmd near the end of the page: pactl manpage
下面是从搜索其他链接，可能对你有用：
Here is another link from that search that might be useful to you:
