Some questions about devices supported by alsa

Some questions about devices supported by alsa

[Sergio Atzori]

Hello, my name is Sergio Atzori. I'm a musician and I love very much
linux and open source. I have a lot of hardware for music, something
well supported by linux, something else not supported...I have some
questions:
1) Esi Juli@: reported as supported by alsa, but it isn't. Looking at
http://www.linuxdriverproject.org/twiki/bin/view/Main/DriversNeeded and
http://alsa.opensrc.org/index.php/Ice1724, this really beautiful card is
unusable in linux. I have one and I tried to get it working with some
distros, but nothing..I experience a computer freeze (kernel panic
perhaps?) in every attempt to configure it with alsa-conf, or just
opening an application that uses midi system (like Rosegarden). So I
would know, there is someone working on a better driver? Can I hope to
get it working in the near future? According to me there is a lot of
people waiting for a driver for this card, I'm waiting since 2005..
2) Miditech I2 control-37 (http://www.miditech.de/produktee_i2.htm):
beatiful usb-keyboard, not mentioned in Linux-USB device site, it does
not work in linux...I think the kernel configure it well (as
snd-usb-audio device) but I can't see it in Jack midi connections..
3) RME AES32 (and AES32express) & Lynx AES16: this driver could be
important for professional studios..if we want to put linux distros on
the professional side. I've none of them, but some people ask me to
build a professional multichannel live machine, I'd like to build a
linux based machine...there are not alternatives to these cards, because
I can build a system with more than one of them (really powerful
multichannel environment).

Thanks so much for attention.
Ciao

The RME HDSP MADI (PCI and PCIe versions) work on Linux. I'm
surprised their AES32 cards don't though. Are you sure about this?

Hi Sergio,

Esi Juli@ seems to be a different beast than most other ice1724-based 
cards. I am working on the driver, it will take a number of changes to 
the generic ice1724 driver due to presumably different clocking scheme.

The ice1724 midi driver has a bug causing kernel hang when opening the 
device. It has been reported, and Takashi has provided an experimental 
patch.

http://mailman.alsa-project.org/pipermail/alsa-devel/2007-April/000641.html

It would be great if you were able to test the patch. The midi device 
should work (hopefully) using the existing driver for Juli@.

Thanks a lot,

Pavel.

Does it appear in the output of "amidi -l"?
Does it appear in the output of "aplaymidi -l"?

Just a notice - these commands must be run with Juli's driver unloaded 
(rmmod snd-ice1724) otherwise it locks up the kernel when opening Juli's 
midi device registered in alsa midi. Been there, done that :)

Regards,

Pavel.
