Hello list,
I have a Sound Devices that always worked perfectly fine out of the box as
a generic USB device, without need of asoundrc or anything.
But now for some reason it works as playback device, but is not recognized
as capture device.
Below I pasted the output of the alsa_info script, where you can see that
arecord -l returns nothing and there is no capture device under /dev/snd.
The card itself works fine on other machines, including one with a very
similar gentoo system installed by myself, also without asoundrc or any
special configuration.
Any help would be greatly appreciated, because I have no idea where to
start looking.
