Hi All... A couple of weeks ago, I went digging for a patch that adds support for the O2's onboard sound. Google cache (linux-mips.org was down at the time) managed to reveal a patch against 2.6.12-rc2[1]. Since then, snd_hidden_kcalloc and snd_hidden_kfree have disappeared. I can get the driver to compile and semi-work by replacing those with kmalloc and kfree ... but I'm not sure if that's correct or not. Under a 64-bit kernel (built with gcc 3.4.4, binutils 2.16.1), the driver loads, but the audio output is badly distorted. Having never used an O2 before, I can't vouch for this being any better or worse than the original driver, although I'm told it has never worked correctly. The patch, as it stands now, is available here: http://dev.gentoo.org/~redhatter/mips/sgi/ip32/patches/ip32-audio-2.6.15.diff.gz Does anyone have any docs, or useful tidbits on how this hardware works? I'd like to assist get this driver fixed if I can. It almost works (for playback). Regards, -- Stuart Longland (aka Redhatter) .'''.
