hdspmixer

[Jaroslav Kysela]

Hi,

 	working on new ALSA release, but it seems that 
alsa-tools/hdspmixer is out of sync with current 
linux/sound/hdsp.h / hdspm.h after this commit:

commit e24e56795ea57e3dd7da45063ab71f04e231192d
Author: Adrian Knoth <adi@drcomp.erfurt.thur.de>
Date:   Sun Jan 9 19:42:59 2011 +0100

     Add support for RME MADI, RayDAT and AIO

     Merged the work by Florian Faber that's distributed separately as
     hdspmixer64.

     Code taken from 
http://wiki.linuxproaudio.org/index.php/App:hdspmixer_64

     Signed-off-by: Adrian Knoth <adi@drcomp.erfurt.thur.de>
     Signed-off-by: Takashi Iwai <tiwai@suse.de>

 	Any clue what to do to get things fixed?

This requires some work from Adrian...

[Fredrik Lingvall]

I did two things to build the hdspmixer I got from Florian.

1) Moved the #endif (at line 121)

#endif                /* __SOUND_HDSPM_H */

downto the last line of the hdspm.h

2) Changed

#include<alsa/sound/hdsp.h>

to

#include <sound/hdspm.h>

in HDSPMixerWindow.h

It's already in hdspm.h we have in the GIT kernel tree:

http://git.alsa-project.org/?p=alsa-kernel.git;a=blob;f=include/sound/hdspm.h;h=81990b2bcc981bb4f31cae44616aa052c5f1066e;hb=HEAD

I have both includes in HDSMixerWindow.h:

#include <alsa/sound/hdsp.h>
#include <alsa/sound/hdspm.h>

The hdspm.h is from the location above (added to alsa-lib/include/sound 
tree).

I think that you are using different kernel driver - so we are out of 
sync with the user space tools. What version of the hdsp/hdspm driver are 
you using?

That's very likely. The commit was ment to amend ongoing work on the
hdspm driver, but it took me a little longer to get it done. (I
completed it yesterday, but I still have to send the patch)

Find attached the hdspm.h I'm going to send today (hopefully; like
always, time is the foremost problem).

With this file, I'm able to compile and run hdspmixer.

The one I got by email from Florian on 2010-10-27 (I have attached the
32kB tar file). The one on 
http://wiki.linuxproaudio.org/index.php/Driver:hdspm is newer
(2010-12-25). I will check if I can get hdspmixer to build against the
2010-12-25 version.

Thanks.  Feel free to submit the rest ;)

I have now build the hdspm driver from:
http://wiki.linuxproaudio.org/index.php/Driver:hdspm (2010-12-25)
and the hdspmixer (hdspmixer_64-1.9) from:
http://wiki.linuxproaudio.org/index.php/App:hdspmixer_64

I did this by copying the hdspm.c file to the (gentoo kernel)
/usr/src/linux-2.6.36-gentoo-r5/sound/pci/rme9652/hdspm.c
and the hdspm.h file to /usr/include/alsa/sound/hdspm.h and
/usr/include/sound/hdspm.h (had to change the include path for hdspm.h
in hdspm.c as well).

Both the driver and hdspmixer build fine.

There are some differences to the driver at:

http://git.alsa-project.org/?p=alsa-kernel.git;a=blob;f=include/sound/hdspm.h;h=81990b2bcc981bb4f31cae44616aa052c5f1066e;hb=HEAD
http://git.alsa-project.org/?p=alsa-kernel.git;a=blob;f=sound/pci/rme9652/hdspm.c;h=f5eadfc0672ab0073db93f8fe2b484069b42c814;hb=HEAD

At a quick glance I could see that Florian's name was missing in the
MODULE_AUTHOR section for example.

There is also one problem that I have with the driver and and MADIFace
plus a RME M-32 ADC (on a Macbook Pro running x86_64 Gentoo) - the boot
sequence hugs if I have the coax MADI input connected and switched on.
By toggeling to MADI optical during boot is boots fine and I can
afterwards switch back to coax after boot and the card and driver works
fine.
