[alsa-devel] Recording support for Roland SD-50 USB Audio device

[François Isabelle]

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
