The second RFC for implementing the VirtIO Sound card as described in the virtio specs. Sorry for the absence of activity on this.
The output from the sound card works. What remains to be done: - Features defined in PCM features. (Eg message polling) - Channel maps - Jack remaps - Input I will work on the input after I have implemented the output along with all the features since at that point it should just be a matter of reversing a few things in the code that writes the audio. I can work on this patchset mostly on weekends now but I will try to be more regular with this.
