[11:18] <zmagii> Hi guys.
[11:18] <zmagii> How can I configure Jack so that in Ardour it would play back over my computer's speakers?
[11:18] <zmagii> Ardour is connected to my soundcard and hence won't play back---the sound card is USB so play back seems not to be possible.
[11:19] <zmagii> I had a chat here a while ago about how this is simply the way Ardour works and that one can use Jack to do play back over another input/output device.
[14:49] <OvenWerks> zmagii: how are you starting jack?
[14:51] <OvenWerks> zmagii: If you use ubuntustyudio-controls to start jack, then on the audio settings tab->sub tab extra devices
[14:52] <OvenWerks> you should be able to add your internal audio as a jack client
[15:15] <zmagii> OvenWerks: I use the other on, ALSA, in Ardour
[15:16] <OvenWerks> with alsa as Ardour's backend, you can not use two (or more) Audio devices.
[15:17] <OvenWerks> with Ardour 6.0 that may be changed
[15:17] <OvenWerks> (I don't know the device handling that well as I just always have jack running)
[15:18] <zmagii> I don't mind using Jack, but Alsa worked for me. Should I just switch to Jack and see if it works?
[15:18] <OvenWerks> if you want to use usb with internal yes
[15:19] <OvenWerks> but use ubuntustudio-controls to run it
[15:19] <zmagii> Alright, let me try that.
[15:19] <zmagii> It's just so that I can do a second track while listening to playback, basically.
[15:27] <zmagii> Which program should I use to configure Jack?
[15:28] <zmagii> There doesn't seem to be one called Jack.
[15:28] <OvenWerks> ubuntustudio-controls
[15:28] <zmagii> Oh cool alriht
[15:46] <zmagii> I can't seem to get it to work. Where do I choose the internal speakers as output? "Default PulseAudio Output Device"?
[15:47] <zmagii> It also asked for "Jack Master Device (no USB)" but then it actually sets it to "USB Jack Master"
[15:48] <OvenWerks> there is an extra devices tab
[15:50] <OvenWerks> where there is an add devices drop down. select your internal device there and hit "Apply Audio Settings"
[15:54] <zmagii> There are quite a few options there.
[15:54] <OvenWerks> PCH,0,0
[15:54] <OvenWerks> is probably the one you want
[15:54] <zmagii> PCH 0,0 playback and capture CS4206 analog
[15:55] <zmagii> Does it use PulseAudio?
[15:55] <OvenWerks> yes and no.
[15:56] <OvenWerks> there is a pulse->jack bridge
[15:56] <OvenWerks> (by default)
[15:56] <OvenWerks> which connects pulse to the jack devices
[15:57] <zmagii> It looks like it plays back now, yay
[15:57] <zmagii> Strangely the volume looks fixed, should I set output volume in Ardour?
[15:58] <OvenWerks> however, right now the options are only for the system: set of devices and you would want: PCH,0,0 for pulse out
[15:58] <OvenWerks> yes setting the volume in ardour for ardour
[15:58] <zmagii> I set the PCH 0,0 as an output in that popup in Arodur that comes up if you select Outputs in the menu
[15:58] <zmagii> That's seems to be what was missing
[15:58] <OvenWerks> but setting the overall volume use alsamixer or QASmixer
[15:58] <OvenWerks> yup
[15:59] <OvenWerks> if you open Carla and select patchbay. you can see all teh jack connections
[16:00] <OvenWerks> you will probably see that pulse_out is connected to system:playback_1/2
[16:00] <OvenWerks> you may wish to change this to PCH,0,0 as well
[16:01] <OvenWerks> (or just make extra connections)
[16:01] <zmagii>  Alright. If I plug in my headphones, does this become another PCH option?
[16:01] <OvenWerks> you can make new connections in Carla Patchbay by dragging an output to an input
[16:01] <OvenWerks> no
[16:02] <OvenWerks> headphones is a work in progress :P
[16:02] <zmagii> LOL okay np
[16:02] <OvenWerks> you probably need to go to qasmixer or alsamixer and turn the headphones up and unmute them.
[16:03] <OvenWerks> the speaker will not auto mute either
[16:03] <OvenWerks> so mute "Front" to do that
[16:04] <OvenWerks> (on some laptops this is actually labeled "speaker"
[16:05] <OvenWerks> There is ongoing work to autodetect phone plugin and do that automatically. for the next release
[16:06] <zmagii> There is an "Auto-Mute mode" that actually mutes my speaker
[16:06] <zmagii> In QasMixer
[16:07] <OvenWerks> nice
[16:07]  * OvenWerks doesn't actually have anything connected to his internal audio.
[16:09] <zmagii> Do you know whether USB soundcards can actually play back too?
[16:09] <zmagii> Maybe it's too general a question. It's an Edirol that connects to USB with only one channel
[16:10] <zmagii> I am trying to get sound playback on my headphones now... Would it still be PCH 0,0 now?
[16:10] <OvenWerks> I don't know that particular audio device. But many USB devices have both inputs and outputs
[16:10] <OvenWerks> yes your headphones are PHC,0,0
[16:11] <OvenWerks> (Assuiming you mean heqadphones plugged into your computer)
[16:12] <OvenWerks> headphones plugged into the USB device should be system:playback
[16:13] <zmagii> Yes, plugged into the computer
[16:15] <zmagii> TIL my computer has a "Speaker" as well as a "Bass Speaker"
[16:20] <zmagii> I got the headphones to work, but the playback is aweful actually
[16:21] <zmagii> A lot of static sound
[16:24] <OvenWerks> That part I don't know.
[16:27] <zmagii> Thanks for the help
[16:27] <OvenWerks> that sounds like either buffer size or sample rate problem
[16:28] <OvenWerks> sample rate shouldn't be, I think, I added checking the device SR available last release
[16:29] <zmagii> should it be lower?
[16:29] <OvenWerks>  too low of a buffer size might do that too. the buffersize should probably be at least 256 for that set up (or 128 with 3 periods)
[16:30] <zmagii> The sample rate is high at 96 but that matches the USB device
[16:30] <OvenWerks> higher is normally better for this sort of thing.
[16:31] <OvenWerks> try 48000 maybe, your usb device should be able to do that
[16:31] <zmagii> Yes, I'll try, but I'm playing back a recording that was at 96000
[16:32] <OvenWerks> oh, then 96000 it is.
[16:33] <zmagii> If I bounce to a .wav file it's fine though everything sounds good. It's just playback that I am trying to set up
[16:33] <zmagii> If I recorded it with Alsa, would that be a problem
[16:33] <OvenWerks> no
[16:33] <zmagii> If I then playback with Jack using Alsa
[16:33] <OvenWerks> no
[16:34] <zmagii> Alright
[16:34] <OvenWerks> it should not make any difference
[16:34] <OvenWerks> ardour uses the same code as jack internally for alsa
[16:34] <OvenWerks> (Jack and Ardour were written by the same person :)
[16:37] <zmagii> Was that person you...
[16:37] <OvenWerks> no
[16:38] <OvenWerks> I have contributed some code to Ardour, but none of it is DSP code. Mostly it has been remote surface control stuff
[16:39] <zmagii> What is remote surface control?
[16:39] <OvenWerks> it is taking something like this: https://mackie.com/products/mcu-pro-and-xt-pro-control-surfaces
[16:40] <OvenWerks> and using it to control the faders on Ardour.
[16:41] <OvenWerks> the mackie control is MIDI based. I have added a bit to that code but most of my work has been with OSC such as touchOSC kinds of controlers
[16:41] <OvenWerks> most OSC controls are glass rather than physical.
[16:43] <zmagii> Oh that's cool
[16:43] <zmagii> I liked that those expensive Hollywood mixers use Ardour (was it Ardour?)
[16:45] <OvenWerks> Harrison does use Ardour inside it's large format mixing desks (the digital ones) as the recorder. I think most people then use their own DAW sw from there.
[17:11] <zmagii> OvenWerks: Do you know how to set playback volume?
[17:11] <zmagii> I think the issue is that it's maxed
[17:11] <zmagii> I don't want to change the tracks actual volume as it's correct for export
[17:12] <OvenWerks> use qasmixer?
[17:13] <OvenWerks> there should be a PCM control and a master control but I think I would try pcm first
[17:13] <zmagii> So not that volume, the Ardour volume
[17:13] <zmagii> But this is completely solves the issue. I can do -20 db on the playback track and later just change back to 0 db
[17:13] <zmagii> And now the playback is great
[17:14] <OvenWerks> anyway, I have to go out for a while so more answers will be hours away :)
[17:14]  * OvenWerks has a stage to set up
[17:15] <zmagii> No problem at least it works now
[17:15] <zmagii> I can finally add another track
[17:15] <zmagii> Thanks
[17:16] <zmagii> I actually wish I had stages to set up at this point...
[17:16] <zmagii> Enjoy
