Hi,
thanks a lot for taking care for that issue. I just tried it out by modifying the following files from the 2.6.26-rc3 kernel:
sound/pci/Kconfig (modified by hand) sound/pci/ice1712/ice1712.h (modified by hand) sound/pci/ice1712/envy24ht.h (modified by hand) sound/pci/ice1712/ice1724.c (copied from the actual Git snapshot)
I double-checked all the handmade changes, should be ok.
Midi in via "amidi -p hw:0 -d" works now without problem, but when trying to write to the device, for example by "amidi -p hw:0 -s txdata.syx" it causes an immediate crash.
That would not be a problem for me, but jackd probes all ports, and is unusable now.
Perhaps i forgot a patch, is the output working for you?
Hello Martin,
I did check the MIDI output using command
amidi -p hw:0 -S F0411042110C000000000074FF0411042110C000000
Ubuntu Studio 7.10, both -generic and -rt kernel, Audiotrak Prodigy 192, the original patch (I assume the current git version is identical).
There was no MIDI device connected to the output as I have none.
I traced if MIDI-out on Juli goes through the Xilinx CPLD, and it seemed the MIDI lines go straight to the connectors, just as on my Prodigy 192. Unfortunately, I do not have Juli available any more to test the patch.
Please could you provide more details about the crash?
Thanks,
Pavel. _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
Hello Pavel,
i just compiled a new 2.6.25.4 kernel with realtime support. the kernel is from kernel.org, so without any patches except the realtime patch from the alsa wiki.
The alsa source i use is the actual daily snapshot, compiled with
./configure --with-isapnp=no --with-sequencer=yes --with-oss=no --with-debug=full --with-kconfig=ice1724 make make install-modules
This version should have the patches applied, i think.
amidi -l gives the following output: Dir Device Name IO hw:0,0 ICE1724 MIDI , and as written above, amidi -p hw:0 -d works without any problems.
The fault appears immediately after trying to write anything to the hw:0, this
amidi -p hw:0 -S F0411042110C000000000074FF0411042110C000000
also produces a complete freeze of the system. No matter, if my keyboard is attached or not.
That was the first time i compiled alsa with the debugging enabled, and i am currently trying to find out how to use is to give you more information. Is there anything else i can help? I tried to trace myself through the source code, but my knowledge about the used api is very weak...
Thanks much for your help, Martin
