Answers to questions:
Are you sure hw:1,0 refers to your GR-55? Check the entries in
/proc/asound/cards again, please.
cat /proc/asound/cards 0 [U0x46d0x821 ]: USB-Audio - USB Device 0x46d:0x821 USB Device 0x46d:0x821 at usb-0000:00:12.2-1.1, high speed 1 [GR55 ]: USB-Audio - GR-55 Roland GR-55 at usb-0000:00:12.2-4, high speed 2 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xf7ff4000 irq 16 3 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xfbcfc000 irq 19
Note that the position depends on if I start with the device on and connected; as you see above, if I turn it on after startup; it becomes number 3; but for all testing I always startup with it on. ***
Can you try this with a 44100/16bit file?
# aplay -D plughw:GR55,0,0 test-441100-mono-16.wav Playing WAVE 'test-441100-mono-16.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
This did work, I can hear it in the GR-55 Headphone; but only once; it locks up the GR-55 after completing, and I had to disconnect the power, the on/off switch did not work; nor did the midi interface to the instrument.
This may have been working all the time; since it only worked once, I might have missed it; also both wav files worked (48 and 44 khz).

So you DO in fact get audio from the device then with some tool?
Only in Windoze (Vista x64 and Windows 7). ***
For Windows, Midi-OX is a good tool to test with...
I did test Midi-OX in Windows, it worked fine. I also was able to capture MIDI in Pro Guitar 6. *** I tried http://gna.org/projects/gmidimonitor/ and KMidimon with no help *** # amidi -l

*** I updated my troubleshooting file http://vetshelpcenter.com/media/troubleshooting-gr-55.txt It has a lot of information in it. *** I was thinking about writing a tool to help troubleshoot MIDI and Audio ALSA Driver issues with QT4 using Drumstick, do you think this would help?
Do you know of any tools written with it? http://qt-apps.org/content/show.php/Drumstick?content=121300
I can reverse engineer this using Snoopy Pro http://sourceforge.net/projects/usbsnoop/ Would that help?
What next?
Thanks Jeff

That's possible.

Looks ok.

I am facing two problems, I am unfamiliar with this piece of equipment and as a result, I'm unsure how to test it.
Testing Audio function: I tested it with Audacity in Windozes and it works; in Linux I set it up the same way: GR-55 USB Audio (hw:1,0) as recording device; no sound.
Are you sure hw:1,0 refers to your GR-55? Check the entries in /proc/asound/cards again, please.
Using Logitech Webcam software I can record the guitar output; Using Cheese, I do not get Audio.
So you DO in fact get audio from the device then with some tool?
Testing MIDI function: I'm going to call tech support on this one; I have not found a Windows app that seems to work with the MIDI;
For Windows, Midi-OX is a good tool to test with: http://www.midiox.com/
so I can not expect to test this in Linux yet; I would like to be able to convert notes into sheet music; I tried TuxGuitar, but must admit I don't know how to get it to work with MIDI input, or if it even does.
For Linux, use amidi. "amidi -l" will list all available MIDI ports. For example to dump all incoming messages, use "amidi --port hw:X,0 --dump". And to send messages, use "--send-hex" and make sure you send valid MIDI messages, otherwise the other side won't do anything.
I'm going to keep on this till I get it 100%; I have patience; lets hope you do too.
Well, I believe the quirks patch is correct, and there's only software configuration issues left.
