I'd like to contribute an ebuild but haven't done anything like this before. Any advice where to start? I've got a lot of experience with php and a little with shell scripts.

The ebuild would be for alo: a little app which allows ardour to be controlled via LIRC. It's nice to sit back and use the remote.

That sounds useful.

The best thing to do would be to look at other ebuilds and look up info on writing ebuilds. They're really quite simple. If you have a lot of PHP experience and a little shells scripting experience, you'll get the hang of it instantly, I'm sure.

I do not use any of those, so I don't know whether those errors cause troubles when they are actually emerged. Therefore I didn't fill in MantisBT and post here instead.

I'd ignore them and worry only about actual emerge errors.

JACK2, jack-audio-connection-kit, is up to 1.9.6 but this version isn't in the pro-audio overlay. Here's the ebuild for it: http://audiodef.com/gentoo/proaudio/ebuilds/jack/jack-audio-connection-kit-1.9.6.ebuild

I'm newly on amd64 from Intel but mostly doing this sound stuff as a hobby so no big worries if it doesn't all work. But have played around a bit on this new system - got ardour installed no problem (with VST flag) - it is ardour-2.8.7. Installed qjackctl and couldn't get it running with jackdbus until I found this command:
Code:
qdbus org.jackaudio.service /org/jackaudio/Controller StartServer
which seems to work fine - I can start qjackctl and fire up Ardour.

Problem is then getting it to stop and go back to my default system of I suppose alsa/pulseaudio/phonon. I have some media players installed - amarok, etc.. as well as audacity. I've tried that command with ending it in StopServer which seems to work. But what command shall I use to get back to other pulseaudio type apps.. should be pretty easy but my head is swimming on all the googling I've been doing just to get my kernel and some apps like audacity, skype, etc working on this new computer. I know I could just as easy log out and log back in - but cli command or gui would be nice..

thx, JD

How did you get Ardour installed with the VST use flag? That isn't supported on 64-bit systems! 8O

For pro-audio setup on Gentoo, see this.

Well, your inquiry made me double check. Maybe I didn't - I just looked at the emerge -pv ardour and it doesn't directly ask for vst as a USE flag so maybe it didn't. I do have vst and vst-sdk in my make.conf file and didn't have to put any -vst in package.use - so assumed it built with it.

and thanks for the link! Although I read it and doesn't really answer my questions. It uses Pappy Seeds and as far as I can tell he has no kernel seeds for amd platforms, unless I missed 'em. There's some stuff in the link provided about using raw1394 as modules but no explanation - I think I built that into the kernel but I since my system seems to be working as is I don't want to muck too much with it. Is that needed to start jackdbus from qjackctl or does the command I referenced above do it as well?

thanks,
/jd

You missed 'em. 8) Pappy covers things pretty well.

I don't know about jackdbus, as I don't use it. How does it compare to jackd? What advantages does it have over jackd?

raw1394 is for firewire devices, in this case, such as mixers and other audio devices, so I don't think it has anything to do with jack directly, except to be able to start jack to run firewire devices. You also want the ieee1394 use flag rather than freebob. In my experience, freebob causes xruns; ieee1394 doesn't. I don't know why.

Thanks for info! I'll take another look at the kernel seeds.

I'm about to try to re-emerge jack-audio-connection-kit without the dbus flag and my hope is that it gives me back jackd. Right now I have no jackd in /usr/bin/ - just jackdbus (plus other jack stuff). I just cannot find enough info on how to properly use jackdbus - though I did find a few gems. With my setup now, I am unable to get Ardour to output to my speakers. I've followed a few nice tutorials and it seems like it would work, but doesn't. In the past I had several outputs - pcm devices and whatnot (iirc) but now all I have for Ardour outputs on busses and tracks is System playback 1 and 2. (I have the Delta 66 card, as well as built in sound on mb). Audacity outputs fine to the card through alsa - but it must be that jackdbus I don't have configured properly. Looks like I could spend hours configuring the asound.conf file as another variable.

I've also read that pulseaudio can be a problem so last night I got rid of it. Can always bring that back if I figure out this other stuff.

cheers, JD

I see the kernel seeds for x86_64 - that must include AMD64 as well as Intel_64 based.

Anyway - reemerged qjackctl and jack-audio-connection-kit with -dbus and have jackd back. Still can't get it to run as I get the error:
"unknown driver alsa"
same with oss. It seems to start with "dummy"

I've made sure all the apps that would be grabbing alsa were turned off, including trying it under FVWM.

Hey - spent about 3 days mucking around trying to get this to work and could not get past the "unknown driver: alsa" error. Finally went for it and installed jack-audio-kit-2.9999 and all my troubles went away. Back in business... not sure what trouble lay down the road by using that svn version - but for now I've got ardour pumping through my monitors..

I use the svn version, too - the one from the overlay.

Glad you got it working!

I fixed this bug long before for jack-audio-kit-2.9999, that's why it works for you. I remember we were trying to fix freebob support with audiodef at that time. Now I fixed jack-audio-connection-kit-1.9.6, too, also with regards to bug #106 by nilekurt at proaudio.

Thanks keenblade - you're the best! (one of many I'm sure).

Funny that bug never came up when I googled "jackd unknown driver alsa" - perhaps I didn't go far enough back into the results - but the pro-audio bug page didn't ever show up in my search. (Amazing how much Ubuntu comes up these days in searches). I didn't know about the pro-audio bug page or would have searched there first before posting here. Thanks for that link. [edit] oh - I see - no keywords in the metadata of the page... and looks like it was just opened and fixed Nov. 16 - today[/edit]

I probably still have something a bit misconfigured as I have to start jackd from command line - qjackctl doesn't do it. But I will play around with some settings in qjackctl to see if that is the problem.

Did you try qjackctl-9999.ebuild? Actually I use jackdbus not jackd. It should work fine with jackdbus. In qjackctl settings, use something like this:
Server path: jackdbus auto
Driver: alsa
Also check the box "Enable D-Bus interface" from misc tab.
Using both jack-audio-kit-2.9999 and qjackctl-999 works great here.

whoa - as part of my struggles I purged my system of jackdbus. Reason was I couldn't get it working - Audiodef was skeptical sounding - there was little to no info I could find about it on the web. For instance it took me a long time in google to find out how to start it. And I couldn't kill it after it was started short of logging out. Still don't know how to do that.

But on the problem of not getting it to work - perhaps that was because of the bug that wouldn't let it use alsa. (I could get it started, get ardour all hooked up with jamin, jkmeter, jackdbus, etc.. see all the meters happily pumping away.. just no sound through the card.

So - you've issued me another challenge - maybe I'll look at it again. Audiodef asked about why one would use jackdbus - can you explain the advantage over jackd?

appreciate all your help! cheers, JD
