Judging from LKML activity it's actually a higher priority than ever.
I think the issue is that the Linux audio community has not been very
engaged with kernel development lately (except for Fernando) and
naturally the kernel devs will assume that if no one complains to them
then it's all good. The RT kernel work lately has been driven by
traditional hard RT users like simulation, machine control, HPC, etc
who all seem to be happy. Also the kernel RT people are focused on
getting the RT kernel patches into mainline.
Does the Ubuntu RT kernel enable the latency tracing stuff?
