[00:32] <_Tailung_> Sorry I was gone
[00:33] <_Tailung_> Didnt wait for an answer.
[00:33] <_Tailung_> So here is the problem:
[00:34] <_Tailung_> I can´t get pulseaudio working with jack
[01:55] <holstein> _Tailung_: in what way?
[01:56] <holstein> it should literally be setup to work "out of the box".. if you get jack running, you should see pulse sources
[01:56] <holstein> you wont have something running, and be able to switch it"on the fly".. you should test things like this, i say..
[01:57] <holstein> see that jack is running.. with something simple.. yoshimi, or audacious. *then*, try something simple again as a pulse source.. any player playing a file that you know is good
[01:57] <holstein> dont just rush off to the internet with a flash video, and try and play that through pulse and assume the issue is with jack or pulse or jack/pulse
[01:58] <holstein> !proaudio
[11:22] <NoUdevForYou> buenas dias
[12:00] <NoUdevForYou> buenas noche
[12:47] <yabbouno> hello:) i am trying to connect a midi keyboard to ubuntu (acer c720/ crouton based)
[12:47] <yabbouno> it is connected to my pc "lsusb" shows it
[12:48] <yabbouno> but i cannot start a JACK server i think because amidi -l results in "no sound card found"
[12:49] <yabbouno> "Bus 001 Device 025: ID 09e8:0076 AKAI  Professional M.I. Corp. LPK25 MIDI Keyboard
[12:49] <yabbouno> it recognized my midi keyboard already but i cant get the midi signal to the pc :(
[12:51] <yabbouno> whenever i try to open aconnectgui it tells me error opening sequencer, but i managed to open it with sudo and then it even shows me my midi keyboard :s
[12:53] <yabbouno> qsynth regularly fails at creating the audio server
[12:53] <yabbouno> (jack)
[12:54] <zequence_> yabbouno: You don't need jack for midi, and failing to start has nothing to do with your midi devices, unless you are trying to start jack using your midi device as an audio device
[12:55] <yabbouno> hi zequence thank you
[12:55] <zequence> !proaudio
[12:55] <yabbouno> well but what can i do.. i am using qsynth and trying to get a signal :/
[12:56] <zequence> If you need jack audio, then you will of course need to start jack.
[12:56] <yabbouno> i only want midi
[12:56] <yabbouno> i thought it had to use jack
[12:57] <zequence> If you are playing qsynth, then it's not only midi
[12:57] <yabbouno> oh okay?
[12:57] <yabbouno> well i can use different software
[12:57] <yabbouno> im just trying to plug my midi keyboard in
[12:57] <zequence> You are controlling qysnth with midi messages (which is strictly data messages)
[12:57] <zequence> ..but the sound that comes out is pure audio
[12:58] <yabbouno> i see
[12:58] <zequence> So, first, start jack with your audio device
[12:58] <zequence> !proaudio
[12:58] <yabbouno> this is the weird thing, it wont start jack
[12:58] <zequence> Have you selected the correct audio device?
[12:58] <yabbouno> i downloaded the qjackctl
[12:58] <zequence> So, this is not Ubuntu Studio?
[12:59] <yabbouno> :( i dont know ubuntu studio, people in #ubuntu pointed me here because my question was too audio specific
[12:59] <yabbouno> i can use ubuntu studio if its good
[12:59] <zequence> you don't have your system set up for pro audio, but let me show you how to do that
[13:00] <yabbouno> ah
[13:00] <zequence> sudo usermod -a -G audio $USER
[13:00] <zequence> That will put you in audio group
[13:00] <cfhowlett_> #opensourcemusicians
[13:00] <zequence> sudo apt-get install linux-lowlatency
[13:00] <zequence> That will install the low latency kernel
[13:01] <yabbouno> ah the low latency kernel
[13:01] <zequence> Also, make sure /etc/security/limits.d/audio.conf is not named /etc/security/limits.d/audio.conf.disabled
[13:01] <zequence> If so, rename it: sudo mv /etc/security/limits.d/audio.conf.disabled /etc/security/limits.d/audio.conf
[13:02] <zequence> yabbouno: Are you following?
[13:02] <yabbouno> im downloading the kernel and trying to check the audio.conf
[13:02] <yabbouno> but have to reopen a new termianl
[13:02] <zequence> ok, good
[13:02] <zequence> You don't need linux-lowlatency for audio, but it makes performance much better
[13:02] <zequence> you will need to reboot and select that kernel
[13:03] <yabbouno> my audio.conf is named audio.conf
[13:03] <zequence> ThOk, good
[13:03] <yabbouno> :)
[13:03] <yabbouno> yeah i want low latency
[13:03] <yabbouno> i know thats important
[13:03] <zequence> yabbouno: Check this out https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro#UbuntuStudio.2BAC8-ProAudioIntro.2BAC8-1204.Starting_Jack
[13:03] <yabbouno> i didnt know i had to have that kernel though for simple midi input
[13:03] <zequence> It's not only midi
[13:04] <yabbouno> yeah i remember
[13:04] <zequence> If you want the audio to perform well (the sound that comes out), you need low latency
[13:04] <yabbouno> you explained it to me
[13:04] <yabbouno> im on that website already
[13:04] <yabbouno> reading this
[13:05] <zequence> Once you have been able to start jack with your audio card (not your midi device), then go to "Connections" -> ALSA
[13:05] <zequence> You will see midi devices there
[13:05] <yabbouno> okay the low latency kernel even put grub on my system i dont know why but ok
[13:05] <zequence> If your keyboard is connected, it will show there
[13:06] <zequence> Once you open qsynth, or any other application that has midi in/out, it will show in "Connect" -> ALSA
[13:06] <yabbouno> how do i start the low latency kernel?
[13:06] <yabbouno> i see
[13:06] <zequence> You reboot, and select it in the GRUB menu
[13:06] <zequence> If you don't see the GRUB menu, hold down Shift
[13:06] <yabbouno> well im on a chromebook
[13:07] <zequence> ..just before BIOS is done
[13:07] <yabbouno> i dont usually see this
[13:07] <yabbouno> i run ubuntu inside a chroot
[13:07] <yabbouno> i guess this makes it more complicated
[13:07] <zequence> I have no idea
[13:08] <zequence> I would have a computer only for audio and install Ubuntu Studio on it
[13:08] <zequence> Makes things a bit easier
[13:08] <yabbouno> yeah
[13:08] <yabbouno> this is not my main device
[13:08] <zequence> http://ubuntustudio.org/
[13:09] <yabbouno> yeah its nice
[13:09] <yabbouno> i will look into that
[13:09] <zequence> ok, good luck
[13:09] <yabbouno> but without it, is there no way to get sound from my midi keyboard?:( maybe i should ask in #opensourcemusicians
[13:10] <zequence> The link cfhowlett_ gave you is good for anything in linux audio #opensourcemusicians
[13:10] <zequence> In case you have more questions
[13:10] <yabbouno> yeah, ty
[13:10] <zequence> Look, the sound does not come for the keyboard
[13:10] <yabbouno> ill ask there
[13:10] <zequence> Unless you have audio in the keyboard and connect that to a set of speakers
[13:11] <zequence> from* the keyboard
[13:11] <zequence> If you are using the keyboard only as a controller, that is all it does - it controls
[13:11] <yabbouno> yeah
[13:11] <zequence> It can control an instrument, such as qsynth
[13:11] <yabbouno> thats what i want to do
[13:12] <zequence> midi is always on
[13:12] <zequence> if your midi device is working, it should show in Qjackctl -> Connect -> Alsa
[13:12] <zequence> ..even if jack is not on
[13:13] <zequence> In order to get audio from a jack application, jack will need to be runnning
[13:13] <yabbouno> ah okay
[13:13] <yabbouno> then my midi isnt working
[13:13] <zequence> You don't see your device?
[13:13] <zequence> What do you see?
[13:14] <yabbouno> well i see my midi keyboard
[13:14] <zequence> About midi, to make things a bit more complicated - there are two kinds. Alsa midi, and jack midi. But, so far, jack midi is only supported for firewire devices AFAIK
[13:14] <zequence> The "Jack" tab is for jack midi
[13:14] <zequence> Anyway, that's a topic for later
[13:15] <zequence> yabbouno: Do you see it in Qjackctl -> Connect -> Alsa?
[13:15] <yabbouno> lets see
[13:15] <zequence> (jack midi is also supported on a number of applications - and there are ways to bridge alsa and jack midi)
[13:16] <yabbouno> qjackctl says could not open ALSA sequencer
[13:17] <zequence> doesn't matter what it says
[13:17] <zequence> just look in Connect -> Alsa
[13:17] <yabbouno> ah
[13:17] <yabbouno> there is nothing
[13:17] <yabbouno> in neither tab
[13:18] <zequence> trusty?
[13:19] <yabbouno> yep
[13:19] <yabbouno> 14.04
[13:20] <zequence> What do you see from this command: ls -al /dev/snd/seq
[13:23] <yabbouno> crw-rw---- 1 root hwaudio 116, 1 Jul 26 14:27 /dev/snd/seq
[13:26] <zequence> good luck
[22:16] <Munger> Hi guys! I'm trying to use som midi drum patterns and though I'd try using qtractor + hydrogen. Trouble is I don't seem to be getting any sound out. Hydrogen is playing through jack OK, but I can't see any inputs in gladish to connect qtractor to
[22:17] <holstein> Munger: i would start with a2jmidid
[22:17] <Munger> Basically, hydrogen doesn't seem to have any input ports
[22:17] <Munger> Aha...
[22:18] <Munger> I'm a complete newb to midi
[22:18] <holstein> i would try running "a2jmidid" and see if the connections you expect show up where you need. i would be looking in the qjackctl connect panel as well..
[22:19] <holstein> Munger: i would try and simplify the setup.. try connectin *anything* in midi just to make sure you know how
[22:19] <holstein> it'll basically be like you say, though.. and should work like you expect, AFAIK
[22:19] <holstein> Munger: try #opensourcemusicians if its slow here..
[22:20] <Munger> OK. But Am I missing something if I expect hydrogen to have inputs?
