Raspberry Pi - uv4l WebRTC no audio
<p>I've setup up my Raspberry Pi 2 running Wheezy to stream video via uv4l / uv4l-server. I have both a Pi Camera and a USB Microsoft LifeCam HD-5000. I launched uv4l with each driver for each camera and the streaming works fine except for the audio. I'm trying to use my USB webcam as the microphone to stream audio. I read on the uv4l documentation that it picks up the first audio device from "arecord -l" has the audio input and mine prints:</p>

<pre><code>**** List of CAPTURE Hardware Devices ****
card 0: HD5000 [Microsoft LifeCam HD-5000], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
</code></pre>

<p>I changed my /etc/modprobe.d/alsa-base.conf to match the one on this page: <a href="http://www.linux-projects.org/modules/sections/index.php?op=viewarticle&amp;artid=14" rel="nofollow">http://www.linux-projects.org/modules/sections/index.php?op=viewarticle&amp;artid=14</a></p>

<p>I can record audio and play it back by doing:</p>

<pre><code>arecord -D plughw:0,0 -d5 test.wav
aplay -D plughw:1,0 test.wav
</code></pre>

<p>Can someone please point me what I'm missing to be able to stream video and audio via uv4l?</p>

<p>Thank you!</p>
