Plan 9 has long been able to drive SoundBlaster 16s and clones and now can drive USB audio devices. Ken collected ~160GB of PAC-encoded music on choline, our old file server. PAC is Perceptual Audio Coding, also developed at the labs. pacenc and pac[1-4]dec are not distributed, nor is the `audio' GUI command to control playing PAC-encoded music. PAC nominally compresses music 14:1 and the sound quality is quite good. So those 160GB correspond to about 2.24TB, probably a little less. A PAC-encoded album might take 45-65MB, with songs taking about 3-9MB. Ken ended up using an 8-processor x86 (Pentium Pro, I think) system to rip CDs by handing a track to each processor to encode, which really sped up the process. So from my perspective, there's lots of audio support in Plan 9, though it may appear less so to most people.
