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