Still no luck; I spent most of the day researching and trying things.
This is a file of what information I could dig up; it should be useful http://vetshelpcenter.com/media/trouble-shoot-gr-55.txt
Are there any programs/scripts I can install/run that will help trouble shoot this?
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?
