Ok, i will give it a shot to see how it goes..

 We all hope so.

Hmm, maybe i'll drop andrew an email to see what his thoughts and plans
on the issue are..

 
  What about the 2.4.x capabilities patch? Will this work on 2.6.x?
 
 Yes, I think it will.  But, 2.6 provides a mechanism for doing this as
 a kernel module with no patches required.  Here is an experimental
 module I built based on earlier work done by Torben Hohn...

Okay :) I will try it..

Thanks for the infos..

[linux-audio-dev] low latency 2.4.x - 2.6.x

2003-12-21 Thread Florian Schmidt 

Hi,

i wonder about how ready linux 2.6.0 is for audio stuff? Is vanilla
2.6.0 with preemtion enabled comparable to 2.4.22 with preemption +
andrew's LowLatency patches [which i use right now]?

patches. Is there any truth to that?
