I have now got 4 channel recording using arecord.
It seemed the alias for the ctl was throwing the equation.
Use the following in your .asoundrc file.

# compose 4 channels from two channel x two devices, hw:2,1 and hw:2,2
# assuming that hw:2,1 and hw:2,2 give the same condition,

It is the normal mode of operation for memory-mapped IO.

The way you'd do this is to link the capture and playback streams of

we still haven't established the timing for this. its possible that

By the way, I tried to search for the same code in rme9652.c, and found
something similar, but it does not seem to activate both capture and
playback with a single write to the control register. I'm not sure how
the hardware works (nor the driver) though so I may be wrong.

I've looked through some driver code, and if I understand it correctly,
it seems like some drivers, for example the ens1370, check in the
trigger function the substream is linked with other substreams on the

Hi,
my new USB-MIDI-Keyboard has two USB subclasses usb-midi and usb-audio.
Evolution, the manufacturer, told me it's an Audio Class compliant device,
but I don't find a new entry in /proc/asound/seq/clients after loading the
modules.
cat /proc/bus/usb/devices

At the moment I am considering using perl or mysql. Does anyone know
which is easier to setup to do the following.
Parse the INSTALL file for a module name.
Return the info for that module.
