[linux-audio-user] ppc audio input..

hey! i'm new to this list, so hello to all out there, excuse my overzealousness as i immediately launch into a question! i'm a fairly experienced linux user but this one has me baffled.. i have linux installed onto an old blue+white g3, and not the first time either, this is a fresh install of gentoo, in the past i've run with the old stable 2.2kernel debian systems which worked fine... but this install is a little different, i have decided to run the g3 dual boot with macos9 *shock horror*, and to my surprise i have now lost the ability to get any sound input.. i'm using the g3 internal soundcard (chip=burgandy) with both the oss-lite and alsa drivers.. neither driver has improved the situation.. for a bit of clarity, no sound is passed through the chip, and capture/recording doesn't work for any of the inputs, in fact in alsa there are no capture devices available at all and an inspection of '/proc/asound/card0/pcm0c/sub0/status' reveals the unfortunate message 'closed'.. on the flipside, os9 has no problems with sound input, which leads me to suspect that it has control of an internal setting that linux does not.. i have tried reseting the PRAM, which supposedly resets macs internal settings to the factory default but this does very little to solve my problem. considering i use linux for 99% of my audio computing this problem is just a little bit frustrating.. can anyone shed some light, or perhaps tell me who to politely abuse! btw, i tried alsa-user-list but my msg is trapped in the moderation blackhole... i am running kernels: 2.4.22 & 2.6.3 i have alsa 0.9.7 & 1.0.2 sound *output* works fine! cheers, dmotd.
