just to be clear... there will be *no* official kernel-rt.. we will (hopefully, after testing and approval, and much deliberation) have the *-lowlatency one in the repos, and as the default kernel for US.<div> <div class="gmail_quote"> On Sun, Nov 13, 2011 at 11:08 AM, Ralf Mardorf <<a href="mailto:ralf.mardorf@alice-dsl.net">ralf.mardorf@alice-dsl.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <div class="HOEnZb"><div class="h5">On Sat, 2011-11-12 at 08:55 -0500, Mike Holstein wrote: > > > On Sat, Nov 12, 2011 at 6:56 AM, Ralf Mardorf > <<a href="mailto:ralf.mardorf@alice-dsl.net">ralf.mardorf@alice-dsl.net</a>> wrote: > -----Ursprüngliche Nachricht----- > Von: <a href="mailto:ubuntu-studio-devel-bounces@lists.ubuntu.com">ubuntu-studio-devel-bounces@lists.ubuntu.com</a> im Auftrag > von Len Ovens > Gesendet: Fr 11/11/2011 19:06 > An: Ubuntu Studio Development & Technical Discussion > Betreff: extra background stuff and work flow idea > > > > > On Thu, November 10, 2011 1:00 pm, Luke Kuhn wrote: > > > > While we are on the subject of background processes that are > resource > > hogs, Pulseaudio is in my experience among the worst > offenders. > > This got me thinking...

Still my stable DAW is Ubuntu Studio, but currently I test Debian testing and the easiest way for Debian seems to build two dummy packages, libcanberra-pulse_2011-dummy_all.deb and pulseaudio_2011-dummy_all.deb, since gnome-core forces to install those packages, after the upgarde from GNOME 2 to GNOME 3. With this dummies audio for non-jackd apps (at least for flashplayer and media player apps) still is ok. IIRC you switched to XFCE?! A good choice. My Ubuntu Studio is still running with GNOME 2 and for Debian I've got a backup with GNOME 2, but I'm testing GNOME 3 in fallback mode. I suspect it as too buggy gfor a DAW, anyway fallback mode could become ok. I experienced issues for my Envy24 cards when using pulseaudio, while for my new RME card things seems to be easier, but I didn't do serious tests. <div class="im"> > kernel-rt is over. here is what the debian multimedia team states > about it from here @ > <a href="http://wiki.debian.org/DebianMultimedia#Realtime_kernel" target="_blank">http://wiki.debian.org/DebianMultimedia#Realtime_kernel</a> </div>This isn't a complete information. From time to time I get in contact with Robin, while the audio community test a preempt kernel with threadirqs enabled even kernel-rts ex 3 with and without NVIDIA patches are tested. <div class="im"> > "The Debian Multimedia team is not working on including a kernel image > with the realtime-patches applied in Debian.

I suspect that they still try to include a real kernel-rt. <div class="im"> > i know its going to be challenging to let go of the mentality that we > need a realtime kernel. we hope to have the -lowlatency kernel > included by default this cycle, and we are planning on doing some > testing/benchmarking with different equipment and the -generic vs > -lowlatency kernels over the next few weeks. > > > there will *not* be a kernel-rt included this cycle. if someone would > like to instigate the inclusion of a kernel-rt, you are welcome to > come on the IRC and go through the same avenues that we (mostly Scott > Lavender) have been going through to get the -lowlatency kernel > (potentially) included in the main repository for the past 3 cycles. > if the kernel is not in the main repos, we cant ship it.

I agree that PA not always is a PITA, but it can become a PITA. Perhaps a FULL preempt kernel with threadirqs could replace a kernel-rt, dunno. I'll install next Ubuntu Studio release and ASAP I'll test different kernels, but I won't install PA. Hard times ;). Cheers!
