Hi.
I'm unable to record using the Roland SD-50 on Linux.
My alsa configuration is available at the following address:
http://www.alsa-project.org/db/?f=19aeffd0d30e952fdd12d589929fbe2a0f98ad7f
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, I'm pretty sure there is simply some mix up in the mixer
configuration... and I'd like to contribute making it work. ( I have
some programming stills :-) )
Although Alsa with Jack and Ardour makes a pretty decent and promising
environment for audio production on Linux. It's hard to believe that
device support is still an issue after more than 20 years of Linux, darn
manufacturers !
On another note, if anyone has a good recommendation for USB Midi+Audio
+ Sound Module to replace this SD-50 on Linux , I'd be willing to hear
about it...
I want the sound module to be able to use it when not connected to a
computer.
I want USB because I don't want to take it off with the laptop as well.
I really though the SD-50 would make my day...
Thank you.
François

What exactly is the problem and how did you test? What does 'arecord
-Dplughw:3 file.wav' say?

I tried the "input" view meeter in pavucontrol first.
And this is what I get when trying the record from the command line:
isabellf@brahms:~/alsa-driver$ LC_ALL=C arecord -Dplughw:3 file.wav
arecord: main:722: audio open error: Device or resource busy
I also checked the alasmixer capture parameters it says:
This sound device does not have any capture controls.

Then some other application has control over the device, most probably
pulseaudio or JACK. Check if prepending arecord with "pasuspender --" helps.

That can well be. alsamixer only lists controls that are exposed by the
hardware, and there might well be none.

You were right, but now the read seems to block..

OK, the kernel is new enough.

So it works only if both playback+capture are used?

If so, the configuration cannot be accessed from the computer.
Check the device settings.
(Do the current settings work with Windows?)

yes, I'm on Ubuntu 14.04

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 ...

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 ?

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.

This is because of some error message that was repeated too often.
That comes before these "callbacks suppressed"?

Only the detection of the device.
But you know what ?! I found at that the device no longer records on Windows either and I think the input might be broken (barely audible white noise at maximum gain) , I'll have it checked by a tech.
Thank you
François
