| 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. | 11:18 |
| 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. | 11:19 |
| OvenWerks | zmagii: how are you starting jack? | 14:49 |
| OvenWerks | zmagii: If you use ubuntustyudio-controls to start jack, then on the audio settings tab->sub tab extra devices | 14:51 |
| OvenWerks | you should be able to add your internal audio as a jack client | 14:52 |
| zmagii | OvenWerks: I use the other on, ALSA, in Ardour | 15:15 |
| OvenWerks | with alsa as Ardour's backend, you can not use two (or more) Audio devices. | 15:16 |
| 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) | 15:17 |
| 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 | 15:18 |
| 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. | 15:19 |
| zmagii | Which program should I use to configure Jack? | 15:27 |
| zmagii | There doesn't seem to be one called Jack. | 15:28 |
| OvenWerks | ubuntustudio-controls | 15:28 |
| zmagii | Oh cool alriht | 15:28 |
| zmagii | I can't seem to get it to work. Where do I choose the internal speakers as output? "Default PulseAudio Output Device"? | 15:46 |
| zmagii | It also asked for "Jack Master Device (no USB)" but then it actually sets it to "USB Jack Master" | 15:47 |
| OvenWerks | there is an extra devices tab | 15:48 |
| OvenWerks | where there is an add devices drop down. select your internal device there and hit "Apply Audio Settings" | 15:50 |
| 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 | 15:54 |
| zmagii | Does it use PulseAudio? | 15:55 |
| OvenWerks | yes and no. | 15:55 |
| OvenWerks | there is a pulse->jack bridge | 15:56 |
| OvenWerks | (by default) | 15:56 |
| OvenWerks | which connects pulse to the jack devices | 15:56 |
| zmagii | It looks like it plays back now, yay | 15:57 |
| zmagii | Strangely the volume looks fixed, should I set output volume in Ardour? | 15:57 |
| 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 | 15:58 |
| OvenWerks | if you open Carla and select patchbay. you can see all teh jack connections | 15:59 |
| 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 | 16:00 |
| 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 | 16:01 |
| 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. | 16:02 |
| OvenWerks | the speaker will not auto mute either | 16:03 |
| OvenWerks | so mute "Front" to do that | 16:03 |
| OvenWerks | (on some laptops this is actually labeled "speaker" | 16:04 |
| OvenWerks | There is ongoing work to autodetect phone plugin and do that automatically. for the next release | 16:05 |
| zmagii | There is an "Auto-Mute mode" that actually mutes my speaker | 16:06 |
| zmagii | In QasMixer | 16:06 |
| OvenWerks | nice | 16:07 |
| * OvenWerks doesn't actually have anything connected to his internal audio. | 16:07 | |
| 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 | 16:09 |
| 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 | 16:10 |
| OvenWerks | (Assuiming you mean heqadphones plugged into your computer) | 16:11 |
| OvenWerks | headphones plugged into the USB device should be system:playback | 16:12 |
| zmagii | Yes, plugged into the computer | 16:13 |
| zmagii | TIL my computer has a "Speaker" as well as a "Bass Speaker" | 16:15 |
| zmagii | I got the headphones to work, but the playback is aweful actually | 16:20 |
| zmagii | A lot of static sound | 16:21 |
| OvenWerks | That part I don't know. | 16:24 |
| zmagii | Thanks for the help | 16:27 |
| OvenWerks | that sounds like either buffer size or sample rate problem | 16:27 |
| OvenWerks | sample rate shouldn't be, I think, I added checking the device SR available last release | 16:28 |
| 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) | 16:29 |
| 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. | 16:30 |
| 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 | 16:31 |
| OvenWerks | oh, then 96000 it is. | 16:32 |
| 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 | 16:33 |
| 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 :) | 16:34 |
| zmagii | Was that person you... | 16:37 |
| OvenWerks | no | 16:37 |
| OvenWerks | I have contributed some code to Ardour, but none of it is DSP code. Mostly it has been remote surface control stuff | 16:38 |
| 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 | 16:39 |
| OvenWerks | and using it to control the faders on Ardour. | 16:40 |
| 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. | 16:41 |
| zmagii | Oh that's cool | 16:43 |
| zmagii | I liked that those expensive Hollywood mixers use Ardour (was it Ardour?) | 16:43 |
| 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. | 16:45 |
| 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 | 17:11 |
| OvenWerks | use qasmixer? | 17:12 |
| 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 | 17:13 |
| 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 | 17:14 | |
| zmagii | No problem at least it works now | 17:15 |
| zmagii | I can finally add another track | 17:15 |
| zmagii | Thanks | 17:15 |
| zmagii | I actually wish I had stages to set up at this point... | 17:16 |
| zmagii | Enjoy | 17:16 |
