Anybody with a working install using a pi zero w. pi cam V2 AND audio?
I get the cam working just fine, streaming at low CPU usage. using alsa to add audio from a usb mic only results in chopped up audio in the stream.

```           "platform": "Camera-ffmpeg",
            "cameras": [
                {
                    "name": "PiEye",
                    "videoConfig": {
                        "source": "-f alsa -ac 1 -ar 44100 -thread_queue_size 512 -i plughw:CARD=AK5371,DEV=0 -rtsp_transport tcp -re -r 6 -s 1280x720 -f video4linux2 -i /dev/video0 -vsync 0 -af aresample=async=1 -b:a 8k",
                        "stillImageSource": "-s 1280x720 -f video4linux2 -i /dev/video0",
                        "maxStreams": 2,
                        "maxWidth": 1280,
                        "maxHeight": 720,
                        "maxFPS": 6,
                        "vcodec": "h264_omx",
                        "audio": true,
                        "mapvideo" : "1",
                        "mapaudio" : "0",
                        "packetsize" : 188
                    }
                }
            ]
```
This is my present snapshot. As you can see I fiddled with a few things, to no avail. Thanks!
