[05:22] delt: i would disable or remove one card... it'll make things a lot easier [05:22] that SBlive mic input is no "better" than the other one, likely [06:42] holstein: thanks :) but i [06:42] holstein: thanks :) but i've figured it out... plus having two sound cards is very practical for some uses [06:43] now i just need to figure out how to route the pcm from one app (ie. pianoteq) to the input of an app that's limited to using pulseaudio (ie. skype) [06:44] see, i was just looking for a patch cable that would solve that problem easily (play through one card, sample from the other) ..... but i'm wondering, is there a "cleaner" way to do it? [06:44] oh btw i use that old sb live mainly for the 15 pin midi connector, i have this old yamaha keyboard that i use..... [06:49] anyway, looking to find either a) that patch cable i KNOW i had lying around here just recently, or b) my soldering iron so i can make another one..... can't find either and it's kind of aggravating :/ [06:50] ...so, while we're in the subject -- is there a way to feed the audio output of one alsa/jack program into the input of a program that uses pulseaudio? === Pici is now known as to === to is now known as Pici [17:02] delt: yes.. you can "feed" those.. routing in JACK [17:12] holstein: but i don't see the pulseaudio apps in qjackctl... how do i do it? [17:13] delt: you wont [17:13] delt: *any* application is able to write for pulse audio, since pulse is open.. but, what you are going to have to do is use the pulse dbus [17:13] you wont see a particular applicaiton, but the pulse system where you can route pulse sources to jack [17:14] ah, i see. but how do i do that? [17:14] delt: i can tell you how i do it [17:14] pulseaudio uses alsa as a backend, right? (normally?) [17:14] delt: i open qjackctl, and look in the "misc" tab, anc make sure the "jack dbus" checkbox is checked to enable the pulse dbus [17:15] *then*, i start jack, and look in "connect" in qjackctl, and route what i want where i want [17:17] http://en.wikipedia.org/wiki/PulseAudio [17:17] "In a typical installation scenario under Linux, the user configures ALSA to use a virtual device provided by PulseAudio. Thus, applications using ALSA will output sound to PulseAudio, which then uses ALSA itself to access the real sound card. PulseAudio also provides its own native interface to applications that want to support PulseAudio directly, as well as a legacy interface for ESD applications, making it suitable as a drop-in replacem [17:17] what do i do? i stop jack, and use whatever "normal" audio i want [17:17] i dont see *any* advantage to use jack all the time.. [17:17] ah, thanks for the pointers. i have a lot of reading to do :3 [17:18] or, just load up a live CD, and test [17:18] running multiple audio devices is not trivial [17:18] the alsa labels can change between boot.. [17:19] yeah, that can be a pain :( [17:20] the way i see it, pulseaudio is pretty much equivalent to the windows sound system [17:20] (from a user's perspective) [17:23] oh, i do have "jack dbus" checked normally [17:24] hello? [17:24] hello [17:24] hallo [17:24] wie geht's? [17:25] delt: well, the windows stuff isnt open.. and you dont have a choice about using it or not.. [17:25] first time here, where am i actually? [17:25] delt: the pulse dbus should be enabled by default [17:25] schuster: this is the ubuntustudio support channel.. IRC, on freenode.. [17:25] schuster: freenode #ubuntustudio channel [17:25] schuster: how can we help you? [17:26] well every thing works fine for me. [17:27] i just have a question about pulse audio, I donßt get it. What is it good for? [17:27] great :D [17:28] schuster: http://en.wikipedia.org/wiki/PulseAudio [17:28] it's an audio API that's meant to be easy to use. [17:28] schuster: it provides an easy way for advanced audio features to be implemented [17:29] oh really, it seems to slow down my computer a little bit, is tjat possible? [17:29] that [17:30] when programs are using pulseaudio? [17:30] or just having the process running? [17:31] i guess all the time, it sucks cpu power as shown in top [17:31] schuster: not likely.. how are you determining that pulse is slowing down your machine? [17:31] schuster: how are you testing? with what applications runing what audio? and how? [17:33] it's just a question. i'm not sure its pulse audio. when i run jackd somtimes the computer freezes and pulse audio is indicated to use 70% of cpu power in top [17:36] computer freezes? [17:36] i mean i can't even move the mouse anymore [17:37] ouch.... something's wrong then :/ [17:38] is this a fresh install? [17:38] really? i have firefox running too. When i use ONLY jack and music software everything is fine [17:38] totally fresh install [17:39] schuster: why are you running firefox? i suggest, *not* testing with that, or flash audio [17:40] holstein can probably help you much more than i can. [17:40] schuster: i would do this.. in the "misc" tab of qjackctl, you can disable the pulse to jack dbus.. you untick the checkbox for the jack dbus.. then, test jack [17:40] schuster: then, *if* you dont need both jack and pulse, dont use both jack and pulse [17:40] you can expect a higher CPU usage using pulse through jack.. that is not a realistic test for pulse audio [17:41] ok. i will try this [17:42] i thought pulse audio was the way to use jack and other audio apps together [17:42] schuster: no [17:42] schuster: pulse is *completely* seperate from jack [17:42] schuster: *any* application can write in jack or pulseaudio support [17:42] ok, so no firefox during a jack session. i can live with that [17:43] schuster: i didnt say that [17:43] schuster: i say, dont *test* with that [17:43] schuster: if you are using flash in firefox, thats version 11.. [17:43] http://www.adobe.com/software/flash/about/ [17:43] thank you very much. i will try it tomorrow [17:44] thats not a short-coming or issue with firefox, or linux. not a limitation at all.. adobe is welcome to release flash for linux.. and they did in the past, but now, only chrome gets current flash [17:45] *so* its not a realistic test of the audio subsystems to run older unsupported versions of flash [17:45] you can test with the chrome browser, or the chrome browsers flash version in chromium.. *or* , just isolate the pulse support from the jack support.. and if you dont need both, dont use both [17:46] hmm.. chromium was even worse when using jack. it crashed almost instantly. [17:47] schuster: chromium has *no* jack support.. so, it cant be using jack at all [17:47] schuster: if you mean, when using chromium, the pulse jack dbus crashed, we can troubleshoot that.. but, you need the *newer* version of flash, if you are going to test flash [17:48] schuster: is that what you are doing? flash media? through pulse through jack? [17:48] i understand you. i will try the different settings and see what happens. thank you for your advices. they are very helpfull [17:49] i use ubuntu studio to make music [17:49] i don really care for chromium and firefox. when i use them i simply stop jack [17:50] schuster: thats what i prefer.. i disable the dbus to get "better" jack performance [17:50] when i want "normal" desktop audio, i stop jack and use that.. but, i dont personally need pulse sources typyically in my jack setup [17:50] i used to use it for recording a skype session.. [17:51] yeah, skype only uses pulseaudio [17:55] ok. i really like ubuntu studio. we will use it at live performances. i'm doing all the preparations now. thank you all, it's time for dinner. bye bye [17:56] i try my best to computers off the stage ;)
