[07:44] <phaidros> just as short question, maybe someone knows: how can I enable pulseaudio to keep on playing, even when switching to another user ? (12.04)
[07:45] <ailo> phaidros: I haven't investigated this. It seems it is configured for one user session only
[07:48] <ailo> You want to play music with one user, and then switch to another user to do something else?
[07:49] <phaidros> ailo: exactly, and I want the sound to not stop .. as this is really annoying when switching back and forth :)
[07:50] <phaidros> afaik one could configure pulse as a system service, but there should be a way to do that on a user level ..
[07:54] <phaidros> any ideas?
[07:55] <ailo> phaidros: I just tried doing this in Debian, and it worked (all though it says during boot something about "per user session" for PA)
[07:56] <ailo> phaidros: At which point is audio stopped? When you switch to the login screen, or when you login with the new user?
[07:56] <ailo> I'm on Debian Wheezy which is in many ways quite similar to 12.04
[07:57] <ailo> I did make sure the new user is apart of "audio" groups
[07:57] <ailo> I could try without it
[07:57] <phaidros> ailo: sound stops as soon as I see the login screen
[07:57] <ailo> Ok, so then it is a config thing
[07:58] <phaidros> both users here are group audio, as both can play sound .. just not continuously the same sound :D
[07:58] <phaidros> any idea where that might be configured?
[08:01] <ailo> The audio group is actually not important for PA
[08:01] <ailo> Or, I don't think so anyway
[08:01] <ailo> It is needed to get realtime privilige though
[08:02] <ailo> There's some confusion on that. It seems audio groups is used for two different things or something
[08:03] <phaidros> ailo: realtime is only granted when adjusting so in /etc/sysctl.conf (e.g. for group audio) .. so it is not directly related to the audio group in general (imho)
[08:04] <phaidros> afaics the membership of group audio grants access to the sound system
[08:04] <phaidros> tho, both is no issue here. I still wonder where the "session" is configured and that it "stops" (or better pauses) when switching to a login screen
[08:06] <ailo> phaidros: You can't have access to realtime with jack, if you're not a member of audio group
[08:06] <ailo> While PA is supposed to use another method
[08:07] <ailo> On Ubuntustudio, you become a member by default, for the first user
[08:08] <ailo> But the second will lack membership to some groups, as well as audio group
[08:08] <ailo> phaidros: There are some setting files for PA at /etc/pulse/*
[08:09] <ailo> I don't know much about how pulse is configured, but I guess google is a friend
[08:09] <ailo> pulse is a member of audio group, but to use pulse you should not need to be
[08:11] <phaidros> ailo: yeah, /etc/pulse is a way, but that is a global pulse server .. tho, I am looking for a way to configure that with pulse as it is running ootb
[08:13] <ailo> They are global settings for PA, not for a global server
[08:13] <ailo> If you make settings in  /etc/pulse, they affect all users, not only one
[08:14] <ailo> Let me make a diff between ubuntustudio and debian to find out what the difference is
[08:15] <phaidros> thanx!
[08:25] <phaidros> ailo: any hints?
[08:26] <ailo> phaidros: I only have one clue. I will try change the setting, and see what happens
[08:26] <ailo> bbs
[08:31] <ailo> phaidros: Ok, so I think I may have found it
[08:31] <ailo> Wait, let me try one more thing
[08:44] <ailo> phaidros: I just tried switching users on Ubuntu Studio, and that worked too
[08:44] <ailo> phaidros: Perhaps this only happens when you start a flash players stream?
[08:46] <ailo> I read something about playing flash has worked before, when switching users, but it's not only audio. Also video, so that is interrupted as soon as you get to login screen
[08:46] <ailo> With audio files on hard disk, I don't have this problem. They keep playing
[08:47] <ailo> Ok, gotta go. Hope things get sorted out
[13:29] <studio-user087> hola
[17:49] <dutchie> hey
[17:50] <dutchie> not actually an ubuntu studio install per se, but i've got ubuntustudio-audio installed on my vanilla 12.04 install and i'm having jack issues
[17:50] <dutchie> mainly that there is no system output in patchage or the qjackctl patcher thingy
[17:50] <dutchie> i tried installing pulseaudio-module-jack, but that didn't seem to help
[17:55] <holstein> dutchie: no output from what?
[17:56] <holstein> qjackctl makes no output
[17:56] <holstein> nor does patchage
[17:56] <holstein> i would try running jack as root...
[17:56] <holstein> sudo qjackctl
[17:56] <holstein> if that works, then you can assume the config is good
[17:56] <dutchie> holstein: output to headphones/speakers
[17:56] <holstein> then, if it doesnt work as normal user, you can assume its permissions
[17:57] <holstein> then, when JACK is running as normal user, i would route something simple such as yoshimi or zynaddsubfx to the output
[17:57] <holstein> OR, something like audacious set to use JACK as output
[17:58] <dutchie> there is no output to route yoshimi to
[17:59] <holstein> dutchie: is JACK running?
[17:59] <dutchie> http://imgur.com/ihpww
[17:59] <holstein> dutchie: do you have it configured properly?
[17:59] <dutchie> jack seems to be running fine, at least the console output from qjackctl says so
[17:59] <holstein> dutchie: do you have is set to "duplex" in qjackctl's "setup"
[18:00] <holstein> dutchie: sure, but maybe not configured to work with your hardware
[18:00] <holstein> dutchie: i would close jack and start qjackctl as root
[18:00] <holstein> when you see JACK running as root on your card, and all looks as it should, then you can move on to as normal user
[18:01] <dutchie> same error with root
[18:01] <holstein> dutchie: well, its not an "error"
[18:02] <dutchie> well, no
[18:02] <holstein> dutchie: if you dont have it configured to use your device properly in duplex mode
[18:02] <holstein> OR, if the alsa drivers are not supporting the device
[18:02] <holstein> dutchie: is it set up in duplex mode?
[18:02] <dutchie> yes
[18:03] <holstein> dutchie: you are in the audio tab in "connect" ?
[18:03] <dutchie> yes
[18:03] <holstein> dutchie: i would remove the pulse sync thing, thats not the issue
[18:03] <dutchie> ok
[18:04] <holstein> you can try going one way or the other with alsa
[18:05] <dutchie> what do you mean?
[18:05] <holstein> dutchie: upgrading or downgrading
[18:06] <holstein> i usually try some live CD's...
[18:07] <dutchie> oh right
[18:21] <dutchie> well i just rebooted and now there is a system output
[18:22] <holstein> \o/
[18:24] <dutchie> now i just have to work out what system/capture_{1,2} and system/playback{1..6} are
[18:27] <holstein> yeah?
[18:27] <holstein> just route to them all
[18:28] <dutchie> foolproof!
[18:42] <dutchie> hmm, can't seem to record anything
[18:44] <holstein> dutchie: with?
[18:44] <dutchie> anything
[18:45] <holstein> from?
[18:45] <dutchie> tried ardour, qtractor, audacity
[18:45] <holstein> use ardour
[18:45] <holstein> route *every* input ot *every* output
[18:45] <holstein> its likely you are just getting used to the way it looks/feels
[18:45] <holstein> do you need JACK?
[18:46] <holstein> maybe you'd be OK with pavucontrol and audacity
[18:46] <dutchie> this is the sort of thing i'm not sure about
[18:47] <holstein> keep it simple
[18:47] <dutchie> i have a feeling i'm going to be woefully underequipped for what i want to do hardware-wise
[18:47] <holstein> route a piece of software to another peice of software
[18:47] <holstein> test JACK connections that way
[18:47] <dutchie> makes sense
[18:47] <holstein> if you are using an internal sound card, i would just get *any* USB device
[18:47] <holstein> you can ask in #opensourcemusicians about what is the best around now
[18:47] <dutchie> what i want to do is record some singing, and put it on top of some synthy type stuff
[18:48] <holstein> best for the cash
[18:48] <holstein> dutchie: "recording some singing" is quite challenging
[18:48] <holstein> lets say you want to do that professionally
[18:48] <holstein> you would go somewhere and pay $80/hour
[18:49] <holstein> you are trying to repicate that harware workflow on a sound card that cost 18 cents
[18:49] <holstein> im not saying it cant be done, but you are going to get sub-par results
[18:49] <dutchie> quality is not a huge issue, it's basically supposed to be a romantic surprise for my girlfriend
[18:49] <holstein> i would get an all in one USB device with a preamp
[18:49] <holstein> OR, just use what you got, and deal with it
[18:49] <holstein> OR record the tracks, take them to a studio and sing over them
[18:50] <holstein> dutchie: its *drastic* the difference
[18:50] <holstein> they are not equivalent tools
[18:50] <holstein> the USB device with the preamp is something i would say to use if you are not worried about  the quality
[18:50] <holstein> the internal sound card and mic you are using now is just not for that purpose at all
[18:50] <holstein> thats for skype at best
[18:51] <dutchie> *nods*
[18:51] <holstein> depending on what you are doing, you might knock it out in an hour at a studio
[18:51] <holstein> OR, grab a device for $60 somewhere (or $30 used)
[18:52] <dutchie> fair enough
[18:52] <dutchie> so the singing is going to be hard, but what about the synthy type stuff?
[18:53] <holstein> software synths are just that
[18:53] <holstein> they are generated "in the box"
[18:53] <holstein> so, that'll sound the same on your box, or some studio machine
[18:53] <holstein> doesnt matter
[18:53] <holstein> you'll sound the same as if you are paying $80/hour
[18:53] <dutchie> yep, i got that
[18:55] <dutchie> what would the actual workflow be? put something together in a midi sequencer, feed that into a synth and twiddle dials until cool noises come out? or have i got the wrong end of the stick?
[18:55] <holstein> nah
[18:55] <holstein> its all open, so the workflow can literally be what you like
[18:55] <holstein> i dont do a lot of midi
[18:55] <holstein> i would suggest asking in #opensourcemusicians
[18:56] <holstein> most folks use qtractor as a sequencer
[18:56] <holstein> there are lots of synths and samplers.. but sampling gets into the hardware again
[18:56] <holstein> assuming you want to use your own samples
[18:56] <holstein> otherwise, the tracks are as good as the samples you use
[18:57] <dutchie> right
[18:57] <holstein> with JACK, and a nice interface, you can run out to hardware modules, or effects
[18:57] <holstein> the only limitations with JACK and these open tools are your imagination, skill and cash flow
[18:58] <dutchie> awesome, thanks a lot
[18:58] <dutchie> if we were anywhere nearby i'd probably buy you a drink by now
[18:58] <holstein> hehe.. well, check out my CD...
