[PlanetCCRMA] [PlanetCCRMANews] the Planet lands on Fedora 10

[JOHN LYON]

Thanks for the response.  Lots to think about. 

I agree that if I can get the rt kernel running, no other OS is going to beat it for low latency.  Plus, I've been doing Linux since 1994, and I like it.  

Dumb question, but how do I install the 'nv' video drivers?  Is there an RPM? 

Man, have I tried kernels.  Right now, I'm trying an older 2.6.24.3-1.rt1.2.el5.ccrmart kernel, but I've tried so many.  Nope, it hangs too.  Okay, 'nv' here I come.

If I'm stuck with an non-rt kernel, my question is: can I make Jack work? I know how to set the latencies high, but without a lot of experimenting, I won't know if I can get a decent recording using the non-rt kernel.  Anyone else done this?  (Of course, I can do the experimenting, but I'd be grateful for anyone else's shared experience). 

Thanks for prompt replies,

John
