[pulseaudio-discuss] Generic device names in pavucontrol

[Valmantas Palikša]

OK, I've fiddled around with that udev rule and now it works like it's
supposed to.
And it seems almost everything here is on pci bus 0 :)

$ ls /sys/bus/pci/devices/
0000:00:00.0  0000:00:0f.0  0000:00:10.2  0000:00:11.5  0000:00:18.2
0000:00:01.0  0000:00:0f.1  0000:00:10.3  0000:00:12.0  0000:00:18.3
0000:00:0c.0  0000:00:10.0  0000:00:10.4  0000:00:18.0  0000:01:00.0
0000:00:0d.0  0000:00:10.1  0000:00:11.0  0000:00:18.1
