Re: [linuxdc-dev] aica driver speedup

Adrian,

    If you're not willing to take it as is, you could always add a build
option or module option to skip the sleep at a certain frequency
threshold.  Since most people are building their own kernel, that
would make for a win-win.  Personally, I'm trying to get my dc to the
point that I can use it as a network mp3 player w/ a web front-end
for song selection... I think the less cpu hungry audio driver will
manage that just fine.  Thanks,

	Alex
