Hi POD users!
I just read your messages about using the POD XT Live under Linux. I am
very curious if this actually worked since Line6 told me about modifications
in the audio interface made for the POD XT Live, which I blindly added to the
driver without testing since I don't own a POD XT Live. Please let me know if
you were successful, and if not, what exactly went wrong (syslog etc.), so I
can try to fix it.
Thanks,
Markus

Do the drivers only work on 2.6 kernels? I'm still using a 2.4 kernel.
I'd love to help with the testing.

I will, but it might be a while before I get to it. I am building my
studio and will probably be reinstalling my OS during the changeover.
I have been using 64bit linux and too many audio apps are just not
stable in 64 bit mode.

Mine is ;-) I had to do remarkably few changes when
migrating the driver from
IA32 to AMD64, which is now the platform I am using for development. I don't
know, however, about IA64. Has anybody tried?
Kind regards,
Markus

I'm unable to find _any_ reference to the `snd_podxtpro_audio_t_magic'.
Possibly the _magic is appended by some macro, the rest is available...
Possibly it's kernel dependent...
Try unpacking the files again, perhaps there was a mismatch with some source?
