[01:44] <vihari> erm hey guys
[01:45] <vihari> i guess the laptop died while it was on, and now refuses to boot!
[01:45] <vihari> just a blinking cursor, and cursing
[10:27] <drcce2001[m]> Hi, I have an old Bahringer Eurorack MX2004 analogue mixing console that I use for recordibg. But I am thinking of getting a smaller digital mixer (USB?) to control DAW and NLE mixers more easily. Can anyone recommend one that is known to work well with Ubuntu Studio?
[11:33] <shibetpc> hello. just installed latest ubuntu studio.  all working great, but trying to add HDMI output as a routing possibility in addition to the analog card capture & playback.  ubuntu studio controls sees the hdmi and lets me connect it as an 'Extra Device', but it doesn't show up in Carla. Any idea why? thx :)
[11:50] <vlt> shibetpc: Jack by default only uses one physical device. You’d have to use adapters to attach another one.
[11:51] <shibetpc> how would I go about setting that up?
[12:05] <vlt> shibetpc: Good question. I remember having done that years ago. But unfortunately https://jackaudio.org/faq/multiple_devices.html#2-use-the-jack2-audio-adapters-jack2-only doesn’t have more than "More information is needed on this option" :D
[12:07] <shibetpc> ok.  i'll dig deeper. thanks for the response :)
[16:05] <Eickmeyer> vlt: Ubuntu Studio Controls allows for more than one audio device at a time in Jack.
[16:06] <OvenWerks> vlt: actually, ubuntustudio-controls does add extra devices almost seemlessly. However, hdmi requires very large buffers to work (4096)
[16:06]  * OvenWerks adds hdmi to his list of special casing to do.
[16:15] <OvenWerks> drcce2001[m]: the X32 series and the xair19 work well.
[16:15] <OvenWerks> drcce2001[m]: The xair does not have physical controls though.
[16:18] <OvenWerks> drcce2001[m]: I don't think there are many (any) digital mixer with physical controls that have less than 16 (17 with master) physical faders.
[16:19] <OvenWerks> Allen and Heaths QU series is reported to work well too. (their newer series is unfortunately 96k only, so I would not concider it)
[16:20] <OvenWerks> Soundcraft has a similar unit, but the x32 is probably the cheapest and there are Linux utilities available for it... and better docs than the others.
[16:23] <OvenWerks> The x32 comes in 3 styles: X32, X32 compact and x32 producer.
[16:30] <vlt> Eickmeyer, OvenWerks: Ahhh, thank you! TIL. Hope they’ll come back or find out themselves.
[16:36] <OvenWerks> drcce2001[m]: I think the x32 uses floating point math, beware that the A&H mixers all use int math and so advertize 48 bit or greater (int math requires one extra bit per channel pretty much) but the USB output will still be 24 bit (same with MADI, Dante, etc) The 48 or 64 bit internal bit depth is just to get around using int math. I think using int math allows simpler DSP or is a limitation DSP
[16:36] <OvenWerks> blocks inside. It doews allow lower latency for live use.
[19:37] <drcce2001[m]> <OvenWerks "drcce2001: I think the x32 uses "> Many thanks for the replies.
[19:48] <drcce2001[m]> Do you mean the xair18 or 19?
[19:53] <drcce2001[m]> I found the Behringer XR 18 X Air. Is that the one you recommended?
[19:53] <drcce2001[m]> The x32 looks too big really.
[19:59] <drcce2001[m]> Is there a way of controling DAW mixers from a tablet app? Wirelessly?
[20:24] <OvenWerks> the xair allows that (x32 as well but it is too big) and in fact that is where the air comes from.
[20:26] <OvenWerks> drcce2001[m]: I did not know there was an x19. Check for number of USB channels. I think the smaller versions are onlu 2 USB channels but the larger ones are 18 or so
[20:26] <PLC> mmm X32 here ...?
[20:27] <PLC> hi' :)
[20:27] <PLC> who have X32 under ubutustudio ?
[20:29] <OvenWerks> PLC: I do not know of anyone in this group who has one but on the linux audio users mailing list I have read about a number of people who have
[20:29] <OvenWerks> PLC: the x32 is fully USB 2.0 complient and so works fine.
[20:30] <PLC> I'm going to buy one ... So I'm interesting by thread ^^
[20:30] <PLC> I hesitate between models ...
[20:30] <PLC> X32 Rack , X32 Compact & X32 STD
[20:31] <PLC> of course I need console, but X32 rack may a very interresting solution for stage
[20:31] <PLC> (sorry for my poor english ...)
[20:33] <PLC> I know X32-edit, and it works under Ustudio
[20:33] <PLC> (not under Linux Mint)
[20:33] <OvenWerks> Wow, I guess the x32 has been around a while: https://community.musictribe.com/t5/Mixing/X32-and-Linux/td-p/104718
[20:34] <PLC> yes of course
[20:34] <OvenWerks> http://linux-audio.4202.n7.nabble.com/Ardour-4-X32-and-USB-port-td100819.html
[20:34] <PLC> but it's a very low cost solution for middle app
[20:35] <Eickmeyer> I have used the Behringer X-series in live environments. You really can't go wrong.
[20:36] <OvenWerks> Thats about what I got out of it
[20:36] <PLC> I really hesitate to buy a Mac ... I think , I can't go to win ...
[20:37] <OvenWerks> The normal thing with audio interfaces, if it works with a mac with no drivers, then it will work fine on Linux too
[20:38] <Eickmeyer> The Behringer X-32 works OOTB on Linux. I have first-hand experience with this.
[20:38] <PLC> ohhhh :)
[20:38] <Eickmeyer> So, really any of the X-series is good. I have yet to find Behringer hardware that *doesn't* work with Linux.
[20:39] <PLC> I had a bad trip with my old Mac, so I go underground with Linux .... but it's ok
[20:39] <Eickmeyer> Considering the Behringer consoles actually run Linux.
[20:39] <PLC> I sold ALL my native instruments hardware/software ...
[20:39] <PLC> but I'm not sure I can reproduce all under UBS
[20:40] <Eickmeyer> PLC: There are literally >100 instrument/effect/utility plugins on Ubuntu Studio.
[20:40] <PLC> for home, I think I'm going to buy a X32 Rack
[20:40] <Eickmeyer> And that's pre-installed.
[20:41] <PLC> Eickmeyer, sure, but I take mark under Logic PRo with NI ... (like 1176 / LA2A ...)
[20:41] <PLC> some reverb
[20:41] <PLC> very good one
[20:42] <PLC> I never start a real project with UBS / Ardour for now
[20:42] <Eickmeyer> PLC: if you're on the fence, just try the live ISO. It's all there. You can browse all of the plugins in using Carla to explore your options.
[20:42] <PLC> I'm running UBS on my ssd
[20:42] <PLC> no prob with that
[20:42] <Eickmeyer> If you want a really good reverb plugin, we have dragonfly-reverb in the backports repo.
[20:42] <Eickmeyer> !ubuntustudio-backports
[20:42] <PLC> but I have somy issue with jack
[20:43] <PLC> In fact, I don't really understand how it really work :p
[20:43] <PLC> (the side chain ...)
[20:43] <Eickmeyer> Ubuntu Studio configures Jack. It just runs. You can use Carla to patch different applications and effects together.
[20:43] <Eickmeyer> Rather, Ubuntu Studio Controls configures Jack.
[20:43] <PLC> ok but about Firefox, or other app who don't use Jack ?
[20:44] <Eickmeyer> Those use PulseAudio, which shows up as a device that Jack recognizes.
[20:44] <PLC> (only work with pulseaudio, for example)
[20:44] <Eickmeyer> That's called a PulseAudio Bridge, which you can configure also in Ubuntu Studio Controls.
[20:44] <Eickmeyer> !ubuntustudio-controls
[20:44] <PLC> I look
[20:44] <Eickmeyer> Those links I just posted tell you everything.
[20:45] <PLC> thx for help ! :)
[20:45] <Eickmeyer> You don't need anybody to walk you through it so long as you read those pages.
[20:45] <PLC> I've got a problem for now (without external card for this time)
[20:46] <PLC> I have internal soundcard , and HDMI TV ...
[20:46] <Eickmeyer> Again, all configurable using Ubuntu Studio Controls.
[20:46] <PLC> when I put "HDMI" as default audio output ...
[20:46] <PLC> every boot, every sleep, its swap with internal card
[20:47] <PLC> I think HDMI is discovered after internal card, so routing into it
[20:47] <Eickmeyer> PLC: In that last link, scroll down to where it says "Extra Devices".
[20:47] <PLC> ok :)
[20:47] <Eickmeyer> You're overthinking it and not reading enough. :)
[20:47] <OvenWerks> PLC: for HDMI the buffer size probably needs to be "really high"
[20:48] <Eickmeyer> HDMI and low latency don't mix.
[20:48] <PLC> yes I had a little slow rate to read english ^^
[20:48] <PLC> but it's ok
[20:48] <OvenWerks> every time alsa starts up the device numbers may change. Best not to use "default" as the device
[20:48] <OvenWerks> always use the device name explisitly
[20:48] <PLC> ok not this thing
[20:49] <PLC> I select HDMI is default output
[20:49] <OvenWerks> buffer size 4096?
[20:49] <PLC> Eickmeyer, I read the F**k manual ^^
[20:49] <PLC> I dont know
[20:49] <OvenWerks> most HDMI audio devices need 4096 for buffer size
[20:50] <Eickmeyer> PLC: Please don't even obfuscate foul language here. That's against the Ubuntu IRC guidelines.
[20:50] <Eickmeyer> PLC: OvenWerks is referring to Jack Buffer Size (Latency).
[20:51] <PLC> oops sorry
[20:51] <PLC> jack seem no start at startup
[20:52] <OvenWerks> if the buffer size is too small for the device jack will not start
[20:52] <OvenWerks> (it tends to hang actually)
[20:53] <OvenWerks> also jack does not start at session start unless it was running at session end before
[20:54] <PLC> I have some "human bugs" ... for example I start computer, but not the TV...
[20:54] <PLC> (because remote don't start TV...)
[20:55] <PLC> And I wait behind black screen and in my mind ... Grrrr, this IR remote dont work again ...
[20:55] <PLC> and I start it after boot sequence & startup sequence
[20:56] <OvenWerks> :) jack also won't start if the device name doesn't exist and some hdmi audio doesn't exist unless the monitor is alive in some cases
[20:56] <PLC> What I don't understand, under linux Mint, the lasted selected output source is automaticaly detected if its start (TV for example)
[20:57] <PLC> after
[20:57] <OvenWerks> There is a difference between pulse and jack
[20:58] <OvenWerks> Pulse has spent a lot of time making sure it auto detects everything. jack is quite manual and studio-controls tries to add that automatic part to it. However, studio-controls is very young
[20:59] <OvenWerks> and it does not have the corperate backing behind it that pulseaudio does
[21:00] <PLC> ok
[21:01] <PLC> but for now, I spoke about Pulseaudio , but ok I try to understand jack setup
[21:04] <Eickmeyer> Really, unless you're doing professional low latency audio work and/or require advanced routing, there's no real reason to use Jack.
[21:10] <Minh> hi guys, I have recently updated from 16.04 to 20.04 LTS, and I am currently running into problems using 2nd monitor.
[21:10] <Minh>  partition my laptop to dual boot Mint and Ubuntu Studio. I use a monitor for second display, connected to the laptop via HDMI.I know the monitor works, because it works fine when I run Mint.When I boot into Studio, the login screen is fine for dual display. But once I log in, both screens are messed up. I can still see some images enough to make
[21:10] <Minh> out the taskbar, and some minimal text, but it looks like the image is fragmented into small pieces and stacked on each other.Please let me know how to fix it.
[21:28] <Eickmeyer> Minh: Your upgrade route (EOL 16.04 to 20.04) wasn't supported.
[21:28] <Minh> i didnt do it like that
[21:28] <Minh> i wiped the 16.04 partition
[21:29] <Minh> so my laptop had Mint running first,
[21:29] <Eickmeyer> Ok, then I'd suggest checking in #xubuntu since they maintain the desktop environment.
[21:29] <Minh> oh ok, thanks
[21:31] <Minh> hopefully this works. Ardour 5 seems like a much better software to use than Ardour 3
[21:31] <Eickmeyer> Minh: Barring any help in there (sometimes it can be sparse there) you can always tryin in #ubuntu since it could be a video driver issue.
[21:31] <Minh> yea, lets hope for that
[21:32] <Minh> I know it's not my monitor problemn, because when I boot to Mint, it works fine
