[linux-audio-user] Disabling cardbus prefetch for Echo Indigo

[Jon Stutters]

Hi all,

I'm trying to get an Echo Indigo IO working under Gentoo 2.6.12 kernel. 
  The card's recognized correctly by ALSA and I can play through it but 
all output is badly distorted.

I had the same problem on this laptop under Windows and fixed it using a 
utility from Echo to disable prefetch for the cardbus chipset (ENE 
CB1410).  Does anyone know how to disable prefetch under Linux?  I've 
had a go at hacking the cardbus driver source but I've not got the right 
result yet.

If there are any other good places I could ask about this that'd be 
useful as well.

Cheers,
Jon Stutters
