Not sure when this started happening but this used to work before here on my Archbox. For some reason the capture side of my usb audio interface is not getting any signal it seems but the playback side works fine.
When I use the command below to test the capture ports I get no sound.
$ arecord hw:3,0 -d 10 test.wav
This interface works on another Archbox I have with no problems so not sure why it's giving me a hard time on this one.
Specs for problematic box:
-GAZ87N-wifi board
-4xUSB 3.0, 2xUSB 2.0/1.1
-Intel i54670k cpu
-8GB ram
Not sure why this is happening, maybe kernel configuration, or BIOS config, etc., but any help would be appreciated. Thanks in advance.

What ALSA packages are installed?
Are you sure hw:3,0 is the correct device?
Is the device muted or some other setting disabled in alsamixer?

I have alsa-1.0.29-1 installed and yes hw:3,0 was the correct device. In alsamixer nothing is showing muted and everything is up at 100% but nothing shows up as input it just shows up as 'Out 1' and 'Out 1 1' when filtered to capture only. A little weird.

This may be a kernel bug, check what kernel version this other machine runs and install the same or earlier version from /var/cache/pacman/pkg.

I'm actually running the same kernel on the laptop which is the archbox that works. Both kernels are the latest from arch which is I believe 4.1.4-1 at the time of writing this. This is what baffles me.

Make sure it's plugged into a USB 2.0 port.

Check on the 2.0 port.
