Looks to me like ALSA is recognising the card, and for example recognises some midi capability there, but fails to recognise the PCM (audio) functionality.dArAzAc wrote:Hmm, so ALSA is at least recognizing both cards?

Code: Select all
The MIDI interface is class compliant, and this is what's shown by Jack.
The audio interfaces are marked as vendor specific, so the driver needs
to be changed to support them.
Please try recompiling your kernel with the patch below.
Some M-Audio devices use big-endian samples, so beware of speaker-
killing noise.
It's possible that playback synchronization doesn't work completely.
Please check what happens when you try to play and record with different
sample rates.

Isn't that patch for the FastTrack Pro, not the Ultra?guillermo machado wrote:http://www.joegiampaoli.com/blog/?p=462
Yes, this guide is for FastTrack Pro, but I used it to try to compile a kernel but using the Fast Track Ultra Patch that "_pedro_ " used. He said his FT 8r is now working.raboof wrote:Isn't that patch for the FastTrack Pro, not the Ultra?guillermo machado wrote:http://www.joegiampaoli.com/blog/?p=462

with this patch..... but it didnt worked
I got this mesage:

can you explain how to patch and compile the kernel to able the fast-Track Ultra?
Thanks

Kernel compilation is so far beyond me.
