[13:39] <psc> hi everybody, long time user of u-studio, dist-upgraded it from 12.04 to 16.04 = pulseaudio is choppy
[13:40] <psc> anyone experienced this? when opening pa-vu-control is kind of works but loop from gui to a message telling my Connection to pulseaudio...
[13:41] <OvenWerks> psc: no I have not experienced that unless I have latency set very low.
[13:42] <OvenWerks> psc: also there are some laptops where the internal mic is 48000 only and that causes problems
[13:44] <psc> OvenWerks, latency of my real soundcard (firewire presonus jack is very low), but I also have the internal soundcard of the motherboard (which I don't care much)
[13:44] <OvenWerks> psc are you bridging jack and pulse then?
[13:44] <psc> OvenWerks, yes
[13:45] <psc> will try to disable the motherboard's soundcard from the bios...
[13:45] <OvenWerks> I find that in pavucontrol I have to turn all the alsa cards off
[13:46] <OvenWerks> pulse has trouble with getting sync from jack plus any other cards
[13:46] <psc> I wish I could, but the pavucontrol show only the gui for a short period of time and loops
[13:46] <OvenWerks> skype will not work with jack set lower than 128/2
[13:47] <psc> (Establishing connection to PulseAudio... please wait)
[13:51] <psc> ok on u-studio 12.04 my presonus firewire was not connected by pulseaudio automagically, but now it looks like PA knows how to start my presonus...
[13:53] <psc> perfect disabling my onboard soundcard fixed the problem
[13:55] <psc> BUT (of course more problems): how can I start jack if PA is using my soundcard?
[13:55] <psc> Would be happy to only use jack (with pulseaudio bridge for chrome etc)
[14:12] <OvenWerks> jack asks pulse to release the card.
[14:12] <OvenWerks> what I do ... is tell pulse to not look for alsa cards...
[14:13] <OvenWerks> pactl unload-module module-udev-detect
[14:13] <OvenWerks> pactl unload-module module-alsa-card
[14:13] <OvenWerks> then I use jack_control to setup and run jack
[14:13] <OvenWerks> I have this set to run at session start
[14:15] <OvenWerks> psc: I also do some other things, but that is besides the point.
[14:15] <psc> OvenWerks, qjackctl crash on first load... maybe because it's not able to release the soundcard from pulseaudio...
[14:15] <OvenWerks> psc: I have heard that if you are using the old firewire drivers you have to blacklist the alsa firewire drivers
[14:16] <psc> OvenWerks, trying to find the right combo, right now I am able to use jack with my soundcard
[14:16] <OvenWerks> psc: you can only use FW via alsa or via the the old drivers.
[14:17] <psc> OvenWerks, if I disable pulseaudio configuration presonus OFF, start jack with cadence = OK but no PA bridge
[14:17] <OvenWerks> psc: if you run jackd instead of jackdbus, the pa-jack bridge will not auto connect
[14:18] <OvenWerks> if jackd is running, jackdbus will fail.
[14:18] <psc> Oh good know!
[14:18] <OvenWerks> (also if jackdbus is running jackd will fail)
[14:19] <OvenWerks> qjackctl and jack_control both run jackdbus by default.
[14:19] <OvenWerks> jackdbus does allow making changes in settings without stopping jack.
[14:20] <psc> well I fear that my setup is a bit odd (12.04 -> 16.04)...
[14:21] <OvenWerks> I do not use a fw interface (old ice1712 device in PCI) but my startup file is at http://www.ovenwerks.net/paste/autojack if it is any help
[14:22] <psc> thanks! saved
[14:22] <OvenWerks> psc: the only "non-odd" setup I know of is to use the internal audio junk...
[14:25] <OvenWerks> psc: be warned to turn cadence auto start off to use something like what I have.
[14:25] <psc> i don't want to reinstall from scratch but i have a feeling that this is what I will end up doing...
[14:26] <psc> i will be painful
[14:26] <psc> it
[14:27] <OvenWerks> I haven't tried upgrading so I don't know. I just save my home directory and start over.
[14:29] <psc> Yes, but then I will need to redo USB policy (I have custom USB hardware in my box), disable CPU governor, memory limits etc)...
[14:30] <OvenWerks> psc: make a package :)
[14:31] <psc> you mean .iso / .img of my whole drive and reinstall that?
[14:31] <OvenWerks> seriously, memory limits should be set right from ubuntustudio install.... cpu governor is coming...
[14:31] <OvenWerks> I am told that performance mode uses less power than ondemand...
[14:34] <psc> thanks for all the help OvenWerks!
[14:34] <OvenWerks> no problem.
[14:34] <psc> I have now a setup that works: no pavucontrol, but bridge is working and I can make music
[14:35] <psc> Will stick around in this channel for a few days. Thanks again!
[14:35] <OvenWerks> cool, making music is the most important part
[16:50] <studio-user416> Hello, anybody there?
