Topic: HDSP MADI card with the 1.0.24 alsa driver

Hi All!

I've got an RME HDSPe MADI card with the 1.0.23 alsa driver. All works perfectly except the MIDI over MADI technology. So, i would like install the 1.0.24 alsa driver which supply the MIDI over MADI.

To begin, I've setted up the following packages: alsa-driver-1.0.24, alsa-lib-1.0.24.1, alsa-utils-1.0.24.2. The installation has succeed and the command "amidi -l" shows the new MIDI port: the MIDI over MADI port.

But... the playing function no longer work...
I've tried to play a file with "aplay" but the playing is hatched and too fast. Also, my own playing application does not work.
I meet this problem with the two drivers 1.0.24 and 1.0.25, and with my two PC (Ubuntu 10.04 and CentOS 5.5).
The alsamixer 1.0.24/1.0.25 settings are the same as with alsamixer 1.0.23.
But, the playing doesn't work correctly with the 1.0.24/1.0.25 alsa driver.

Someone can help me to solve this issue?

I thank you in advance!
