<pre>I am using Pulseaudio 1:8.0-0ubuntu3 on ubuntu xenial.
My built in sound card has two analog input devices, one with a single
subdevice, and the other with two subdevices. Here is the output of arecord
-l:
$ arecord -l
**** List of CAPTURE Hardware Devices ****

I would expect Pulseaudio (perhaps module-udev-detect?) to detect and create 3
input sources to allow access to all three subdevices (hw:0,0,0; hw:0,2,0;
hw:0,2,1). This would allow me to record from all three analog input ports at
once. However, it seems that pulseaudio stops looking after it finds the first
subdevice (hw:0,0,0)
alsamixer detects all three capture ports, and allows me to assign each capture
port to a separate input source.
pavucontrol allows me to switch between capture ports on a single input source.
I could understand this for devices with only a single capture subdevice, but
it is severely limiting for a device with more than one capture subdevice.
I wish to use pulseaudio as a mixer for three loopback sources on my HTPC: a
Chromecast audio, my TV, and a phono amp.</pre>
