Anything currently using PA for its output will stop until this is done. I assume inputs is the same thing, but really, if you are recording why would you make such changes in the middle of a recording? - Jackd's latency setting affects PA's CPU usage as PA works to keep up with jackd. However, this doesn't seem to be a problem on most modern (and some less modern) systems. - PA also has an effect on jackd. This is very noticeable if there are two (or more) audio interfaces. If one IF has a higher limit for latency, that limit will be forced on the other card even though it can normally run at a lower latency. If that IF has stability issues those will also show up on the second card even though it normally would be fine. I would not consider any of these things bugs. I do think there needs to be some thought about how US is shipped though.

Ulatencyd would probably be handy for you; it's a supervisor daemon which prioritizes processes for resource allocation, gives some processes realtime privileges if needed and arranges processes in cgroups. It can decrease latency by smarter resource allocation and getting low-priority tasks out of the way of media apps. It's being tested in elementary OS daily builds and the results we've got so far are impressive. I'm currently working with its author on expanding default configs to accommodate more use cases. Another useful thing would be avoiding swapping for as long as possible. In Linux there are several facilities competing for RAM - in Ubuntu's stock configuration executable code often gets swapped to disk to make way for various caches.

I was talking to a user who needs one and I didn't know what to suggest. After looking around I found qmidiroute which works quite well. There is zonage as well, but it is alpha and so not likely to be in our repos soon enough. Anything else I could find was CLI (see midish). I was able to use qmidiroute to split my dx7 to two zones with two patches and cap the velocity on one of the ranges. I could find other uses too... such as changing the sound of one pad on my ancient yamaha DD11 pad set. (yes there are other ways too) 2) there has been some talk of a "record mode". I think the name could changed to "performance mode" as it may be more useful for live use or even video work. Even though ubuntu is moving from unix init to upstart, the idea of runlevels has been preserved.

Firstly, there are discussions about moving the -lowlatency kernel maintenance into the kernel team as it was pointed out that the patch is "something like a two line" patch. I don't actually know how long our patch is. And it seems disproportionate to have to rebuild a new kernel each time of a security update for such a patch. It was suggested that this might become a build option for an existing kernel package maintained by UKT. Initial discussion with UKT have been fairly positive. They were reducing the number of kernel they maintained and it seems that this was contrary to their efforts, but it was also realized that the actual maintenance of this kernel would be minimal. Queries also were presented about UKT's official maintenance and responsibility of the -lowlatency kernel. I'm not sure this was answered directly but it appears that because the kernel would be built by UKT, it doesn't mean that Canonical or UKT </pre> Scott Lavender 2012-05-08T15:37:36 http://comments.gmane.org/gmane.linux.ubuntu.devel.ubuntu-studio/3960 <pre>That for a shared IRQ the graphics will become an unwanted high prio doesn't happen with a kernel 2.6.31-rt19 + NVIDIA 195.36.15 on Suse 11.2 on my machine.
