Confusing output of jack_lsp -A

by Joel Roth

Hi, Today I noticed something odd in the output of jack_lsp -A. I get entries like this: system:capture_1 alsa_pcm:hw:0,0:out1 Instead of what I used to see: system:capture_1 alsa_pcm:capture_1 Is the former correct? If so what does it signify? Regards, Joel -- Joel Roth

Issue with the priority of the sound cards using rtirq

by Ralf Mardorf

Hi :) since I've got a strange issue with rtirq on US Precise only. Is there anybody having a strange output for /etc/init.d/rtirq status too? I remember that there was a post, when US Precise wasn't released. Regards, Ralf PS: You might take a look at http://lists.linuxaudio.org/pipermail/linux-audio-user/2012-May/date.html http://lists.linuxaudio.org/pipermail/linux-audio-user/2012-April/date.html Message: 17 Date: Tue, 01 May 2012 13:17:39 +0200 From: Jeremy Jongepier <jeremy(a)autostatic.com> Subject: Re: [LAU] Issue with the priority of the sound cards using rtirq To: linux-audio-user(a)lists.linuxaudio.org Message-ID: <4F9FC653.9040102(a)autostatic.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 05/01/12 12:09, Ralf Mardorf wrote: > Jeremy, the bad is, that I don't have another PCIe x1 slot:(. > Ah bummer :( >> > In my experience, restarting the script tries to raise the priorities >> > of the threads in RTIRQ_NAME_LIST, but the ones which are already >> > raised aren't lowered even if you leave them out of the list. >> > >> > Try rebooting the computer. >> > >> > Cheers, Pablo > *reboot* > > The reboot doesn't improve anything:(. So the output of /etc/init.d/rtirq status is the same as in the other mail? That's really weird. The only thing I can think of is that something else (another script?) is prioritizing stuff too (like the nvidia and ohci_hcd processes). The steps between the priorities strengthens my suspicion, it should be 5 but some processes do not get a prio that can be divided by 5 (like nvidia which has prio 82). No one on the Ubuntu Studio list encountered the same issue? Maybe Ubuntu (or Ubuntu Studio) prioritizes processes somewhere else. Best, Jeremy
