OK, the kernel is new enough.
yes, I'm on Ubuntu 14.04
I'm unable to record using the Roland SD-50 on Linux.
And when you're playing something at the same time?
I didn't try that so I just did: no success.
I noticed a bunch of these in the kernel logs, wondering if they could have an effect ...

There is something odd with playback as well. With the sound control panel ( unity-control-center ). The test output only works when the SD-50 input is selected from the input tab.
So it works only if both playback+capture are used?
That's not what I meant. I mean that the SD-50 output using pulseaudio only seems to work when the pulse audio default input is set to the SD-50 as well. I think I should probably get pulseaudio out of the mix for now, and focus on the core alsa support. Is this SD-50 card known to work ?
So, I'm pretty sure there is simply some mix up in the mixer configuration...
If so, the configuration cannot be accessed from the computer. Check the device settings. (Do the current settings work with Windows?)
There is very little configuration parameters on the device itself, except input selection for mic/guitar and power selection between bus and power cord. It was working with windows last time I checked and I didn't change it.
Right now, I'm not getting any output when using: pasuspender -- speaker-test -Dplughw:3
But if I deselect and reselect the input device in the audio control panel or select the S/PDIF ouput instead (which the unit does not have) the sound panel built-in sound check starts working again..
This is a big snafu state.
Looking forward for some troubleshooting ... Thanks. François.
