You most probably just have a confusion about the four cards connected
to your computer.

As you can see from your output of /proc/asound/cards, the GR55 is not
the first one, and hence not the default picked by tools like aplay or
amixer. However, it is present, which is a good sign. For further
parsing the contents of /proc/asound, you need to refer to the device
number, which is not 1 (as in "card1") but 3. What does "cat
/proc/asound/card3/stream0" show?

Just try "alsamixer -D hw:GR55" to control the volume levels, or
"amixer -D hw:GR55 controls" to dump them.

And then, try "aplay -D plughw:GR55,0,0 file.wav" for a first output test.

Does that help?
