[02:09] <mikef187> Hello.... I have been using US for about a year and could use some help on 10.10...... one workd.... jackd.... OMG
[02:09] <mikef187> how do I get pulseaudio alsa and jackd to play?
[02:09] <mikef187> play nicely together.
[02:13] <persia> You can try playing with pulseaudio-module-jack, you can use different audio interfaces for pulse and JACK.
[02:14] <persia> There's some discussion planned for UDS to try to figure out what can be done to improve the experience, but I don't think anyone currently *knows* all the problems, let alone how to resolve them easily.
[02:15] <mikef187> First TY for the help, I have tried to use this mod with limites success on 9.10-10.4 but the whole deal confuses me to no end..
[02:16] <mikef187> to complicate matters more, I use a USB sound card when editing music and the built in sound card for daily driver..
[02:17] <persia> Actually, that should simplify matters.
[02:17] <persia> Just have pulse talk to the built-in card and have JACK talk to the USB card.
[02:17] <mikef187> So I sit here at a fresh US 10.10 install with no config edit.. ready to write some scores,..... would you recommend using rosegarden/ardor/hydrogen via USB sound card without jack?
[02:19] <mikef187> OK,, so to use the USB sound I have trouble using ardour as it wants to play via hw:0 ( i think)
[02:23] <mikef187> OK I would like to have Jack use the USB sound card and pulse use the build-in... before plugging in USB SC I have in /proc/asound/cards
[02:23] <mikef187> 0 [Intel          ]: HDA-Intel - HDA Intel
[02:23] <mikef187>                       HDA Intel at 0x97420000 irq 53
[02:23] <mikef187> In the jack config, would this card be hw:0?
[02:24] <persia> Yes.
[02:24] <persia> the "0" at the beginning is the key.
[02:24] <mikef187> ok.... let me slap the secondary SC on and give you more
[02:26] <mikef187> now /proc/asound/cards reads:
[02:26] <mikef187> 0 [Intel          ]: HDA-Intel - HDA Intel
[02:26] <mikef187>                       HDA Intel at 0x97420000 irq 53
[02:26] <mikef187>  1 [Pro            ]: USB-Audio - FastTrack Pro
[02:26] <mikef187>                       M-Audio FastTrack Pro at usb-0000:00:1d.0-1.1, full speed
[02:27] <mikef187> now... how would jack address this card? hw:1 or hw1:1
[02:27] <persia> I think it's hw:1
[02:29] <mikef187> ok.... on the config in jack control config I have ...
[02:29] <mikef187> hw:0      HDA Intel
[02:29] <mikef187> hw:0,0  STAC92xx Alnalog
[02:29] <mikef187> hw:1      Fastrack Pro|
[02:29] <mikef187> hw:1,1 USB Audio 1
[02:30] <mikef187> So I'm guessing that jack sees a total of 4 cards?
[02:31] <nevyn> well 2 cards.
[02:31] <nevyn> hw:1
[02:32] <nevyn> mikef187: to get the wierd modes like 4x48 and 2x96 you may need to patch your kernel.
[02:32] <nevyn> 2x48/24 I think can be done with the stock driver.
[02:32] <persia> mikef187, JACK sees 2 cards, each of which has one set of outputs.
[02:33] <mikef187> OK ... great.... now what (if anything) do I need to change in the "Sound Preferences" app (hardware tab)
[02:33] <persia> Nothing.
[02:33] <mikef187> ok ok ...cool.... this is gerat info
[02:33] <persia> You can check, but you want Sound Preferences to continue to point at the built-in.
[02:34] <persia> Then you tell JACK to point at the USB card (I use qjackctl preferences for this)
[02:34] <persia> You're lucky.  Pulse and JACK don't play together well, but you have two playgrounds :)
[02:34] <mikef187> yeah... well I want youtube, and totem etc to play through hw:0
[02:35] <mikef187> ok I think I'm following you here...
[02:35] <mikef187> so pretty much have the "System" ignore the USB (hw:1) card and have jack alone access this card..
[02:36] <persia> If by "System" you mean pulse, yes :)
[02:36] <mikef187> right.... now... sometimes I won't have my USB card with me... (laptop)....
[02:36] <persia> Two choices in that case.
[02:37] <mikef187> ok
[02:37] <persia> 1) stop pulse if you use JACK, 2) don't use JACK.
[02:37] <persia> Mind you, you *could* fiddle with pulseaudio-module-jack, but I'm not convinced it's perfect, and you probably don't want system alerts over your JACK transport anyway.
[02:38] <mikef187> now ... correct me if im wrong, but without jack my midi timing get real sloppy
[02:38] <persia> Without JACK, you don't want to use ardour, hydrogen, rosegarden, etc.
[02:38] <mikef187> exactly.... smoked a couple sesstions with freaking error "bonks"
[02:40] <persia> Which basically means either A) only use studio apps in the studio when you have your USB card, B) accept that other audio (system alerts, youtube, etc.) will be silent when you use studio apps on the road, or C) carry your USB sound card anyway (or a different one: USB headsets are a popular way to have something portable)
[02:40] <mikef187> right,....
[02:40] <mikef187> Intersting headphone Idea...
[02:40] <persia> Again, the exception is if you fiddle with the pulse jack module, but that's well into experimental territory.
[02:41] <mikef187> ok... now.... I have messed with that mod in 10.4 ... it twisted my brain to hard...
[02:41] <mikef187> now.... with jack running on and killing the pulse server.... I will lose totem and flash etc ...correct?
[02:43] <mikef187> Ty both for your help guys.... I will try this out.
[02:45] <mikef187> ok... one last question... its probably a loaded one...
[02:45] <mikef187> What is ALSA and Pulseaudio to each other?
[03:16] <mikef187> Can I run my system without pulseaudio?
[03:28] <persia> mikef187, Why do you ask?
[03:29] <persia> It will probably only complicate the handling of audio (including coordination with JACK).
[03:29] <persia> But you can stop pulse whilst you use JACK.
[17:49] <vlada> hi guys
[17:50] <vlada> where can I find lowlatency kernels for ubuntu 10.10?
[17:59] <vlada> I'm installing US packages from ubuntu 10.10 vanilla install, to be precise.
[18:23] <astraljava> vlada: Nowhere, they don't exist.
[18:24] <vlada> astraljava, hi
[18:24] <vlada> why's that?
[18:26] <astraljava> vlada: Because the person who maintained the packages felt he wasn't provided enough support from users or developers alike. No testing etc.
[18:31] <vlada> :(
[18:32] <vlada> And I was like... using 10.10 since alpha days. Really sad news. Any plans for the future? Long term releases or such?
[18:32] <astraljava> We're hoping to get -lowlatency as the default kernel, but it's still early in the devel cycle.
[18:33] <astraljava> vlada: https://wiki.ubuntu.com/RealTime
[18:33] <astraljava> vlada: If you care about RealTime, please participate.
[18:33] <vlada> Should be in ubuntu standard repository if you ask me... But, I'm just a user...
[18:34] <astraljava> vlada: Then you might wanna chat with Ubuntu Kernel Team about that.
[18:34] <vlada> astraljava, Not -realtime, but -lowlatency would be great to have installable immediately.
[18:35] <astraljava> vlada: Please read the link I provided, it's covered there...
[18:36]  * vlada is reading
[19:28] <Sebboh> Hey TheMuso, you around?  May I message you?
