Re: [sc-dev] idle scsynth CPU usage

[jonathan segel <jsegel@xxxxxxxxxxxxxxxxxxxxxx>]

keylargo is the internal sound chip controller on the other alu- 
powerbook..
oh wait, maybe it's not. i think "snapper" is the chip. i'm trying to  
remember from configs for when i installed gentoo on a powerbook. the  
device is Texas Instruments TAS3004.

i was wondering if it's the same chip and controller, but now i'm  
gonna have to do more research to figure out what to compare it to!

by different driver i mean something other than the internal one,  
like a digidesign or indigoIO or something?
