white1 | what's the most high-quality way to record in jackd from playback? | 11:56 |
falktx` | if you record in float wav format, it's always going to be 100% equal to what you hear | 12:03 |
falktx` | jack_capture can do that. see cadence-render for an UI for it | 12:03 |
white1 | i know about jack_capture is it similar to alsa_out or not? | 12:08 |
*** yann-kaelig has joined #kxstudio | 12:08 | |
white1 | i came across zita-j2a client and it's said it's higher quality than alsa_out and i wonder if system:playback is the same thing as alsa_out? | 12:09 |
white1 | i mean system : playback | 12:10 |
falktx` | those have nothing to do with capturing audio | 12:10 |
falktx` | alsa_in/out and zita-a2j/j2a are to bridge alsa and jack audio together | 12:10 |
falktx` | jack_capture is to record audio as it's being played | 12:11 |
white1 | so jack_Capture is the best way to record in jackd? | 12:12 |
yann-kaelig | white1: see jack capture as you audio card input | 12:13 |
falktx` | the other tools you mentioned do not record audio | 12:13 |
white1 | i have 2 audio cards and i had strange thing that i set qjackctl to hw:1,0 but jack used hw:2,0 instead | 12:14 |
falktx` | is that related to the previous question? | 12:14 |
white1 | yes | 12:14 |
falktx` | how so? | 12:15 |
falktx` | didn't you want to capture audio from your pc? | 12:15 |
falktx` | or do you want to capture audio from outside? | 12:15 |
white1 | listen, jackd ignored settings in qjackctl and used another audio card, i had to use zita-j2a -d hw:1,0 to get additional output because jackd added another card to sysem playback ignoring the settings | 12:16 |
white1 | i want to capture from pc | 12:16 |
white1 | not from outside | 12:16 |
white1 | i used jack_capture all the time but last time when i gave jack_capture command it did not record anything since jack was using the wrong card | 12:17 |
falktx` | try using cadence instead of qjackctl to configure jack | 12:17 |
white1 | why is cadence better than qjackctl? | 12:19 |
white1 | my cards are assigned numbers in random order at each boot | 12:20 |
falktx` | cadence doesn't use numbers, it uses IDs | 12:20 |
white1 | though i indicated the default card in asound.conf strangely the file was ignored | 12:20 |
white1 | i will try cadence then | 12:21 |
white1 | thanks | 12:21 |
falktx` | asound.conf is useless for jack | 12:23 |
yann-kaelig | white1: what are you two audio card ? take a lok at aplay -l then lsmod |grep snd-* then give the priority of each card module into the alsa.conf file | 12:26 |
white1 | how to give the priority? | 12:26 |
yann-kaelig | then again aplay -l and you will see the change | 12:26 |
white1 | i have audigy card, realtek hd card and nvidia hdmi is also deteced as a card and also usb midi adapter is also deteced as a card so i have random numbers assigned at boot | 12:28 |
falktx` | again, cadence doesn't use numbers | 12:28 |
yann-kaelig | white1: like this options snd-aloop index=0,1 id="LoopCard1","LoopCard2" options snd-hdsp index=2 id="Multiface" This is only an example from my conf, a loopback for non-jack audio applications to became jack compatible and the RME. Then go into qjackctl and configure to the car you want to use globally or for input/output | 12:28 |
falktx` | it uses device IDs | 12:28 |
falktx` | they will remain the same across reboots | 12:28 |
falktx` | yann-kaelig: that is not needed | 12:29 |
white1 | anyway i would like to assign one card as 0 for alsa applications | 12:30 |
white1 | but i think they will observ asound.conf | 12:30 |
white1 | the only thing which irritates is alsemixer because it shows the first detected device | 12:31 |
yann-kaelig | white1: which card is the first device into your aplay -l output ? actually | 12:31 |
white1 | now? | 12:31 |
yann-kaelig | yep | 12:31 |
white1 | hda nvidia | 12:32 |
yann-kaelig | ok and so you dont want this one to be the default first card | 12:32 |
white1 | right | 12:32 |
white1 | i want realtek to take index 0 | 12:32 |
yann-kaelig | ok, to into your alsa.conf give this nvidia module card index=1 and for the realtek module give the index=0 | 12:33 |
white1 | one moment is it /etc/alsa.conf? | 12:33 |
yann-kaelig | /etc/modprobe.d/ it really depend of you OS | 12:34 |
white1 | i use gen2 | 12:34 |
yann-kaelig | so this is the right folder | 12:34 |
yann-kaelig | lokk int oit you will find alsa.conf | 12:34 |
white1 | yes it's there where u told | 12:35 |
yann-kaelig | i know i'm using funtoo ;) | 12:35 |
yann-kaelig | so you have to change some conf for alsa give the output of lsmod |grep snd-* | 12:36 |
yann-kaelig | white1: pv | 12:36 |
falktx` | guys guys | 12:37 |
falktx` | stop | 12:37 |
falktx` | there's no need to use hw:numbers | 12:37 |
falktx` | use hw:NAME | 12:37 |
falktx` | like hw:Intel,0 | 12:37 |
falktx` | or hw:USB or hw:CODEC | 12:37 |
falktx` | aplay -l tells you this value like this "card 0: <NAME>" | 12:38 |
falktx` | take that <NAME> and use it | 12:38 |
white1 | yann-kaelig: one moment i will paste it | 12:38 |
white1 | yann-kaelig: https://bpaste.net/show/9e3c83aba6f6 | 12:40 |

andrew_ | Have a question about fluidsynth and carla plugin host | 16:02 |
*** white1 has quit IRC | 16:05 | |
andrew_ | ok got the fluid synth working but no tux guitar have it installed with jack and it wont show up in carla host | 16:09 |
falktx` | it never does | 16:14 |
falktx` | it's blacklisted | 16:14 |
falktx` | carla handles soundfonts, no need for fluidsynth-dssi plugin | 16:15 |
andrew_ | well then im confused trying to get tux guitar to work,i had to reinstall the iso and now cant seem to get it to work | 16:16 |
holstein | the iso is not working? | 16:17 |
holstein | you reinstalled the OS? | 16:17 |
andrew_ | yes | 16:17 |
andrew_ | sorry really new to all this | 16:18 |
holstein | no worries.. its just that, you didnt *have* to reinstall the OS.. you may have chosen to, and details as to why, and how, can be helpful for a volunteer | 16:18 |
andrew_ | oh somehow the computewr seems to have been corrupted | 16:19 |
holstein | if the "computer" has been corrupted, then, you wont address that with hardware | 16:19 |
andrew_ | so i did a fresh install of the os | 16:19 |
holstein | you *will* address that with hardware | 16:19 |
holstein | not software | 16:19 |
holstein | *if* your hardware, for example, is "corrupt", or broken, you cant reinstall the os to "fix" that | 16:20 |
holstein | so, is your computer corrupted? if so, how? | 16:20 |
falktx` | is tuxguitar-jack installed ? | 16:20 |
holstein | bios? bad hard drive? bad memory? | 16:20 |
andrew_ | well nothing would open it was running real sluggish no i think i got a virus | 16:21 |
holstein | you "think"? you got a virus in what, kxstudio? | 16:21 |
holstein | not likely.. | 16:21 |
andrew_ | i dont know but i reinstalled the os yesterday and everything seems to work now | 16:21 |
andrew_ | tux-guitar jack is installed | 16:22 |
holstein | *everything*? but, not tux guitar? and what else? | 16:22 |
andrew_ | well right now everything seems to work but tux guitar and yes i installed tuxguitar-jack | 16:23 |

falktx` | they changed a bit | 17:19 |
falktx` | if you have issues, update the sources again | 17:20 |
ssj71 | hmm. still no go. I updated to 15.04 so I'm trying to reinstall them | 17:22 |
falktx` | try a purge, the update will have stuff disabled | 17:25 |
falktx` | sudo apt-get purge kxstudio-repos | 17:25 |
falktx` | then enable them again | 17:25 |
falktx` | (see new instructions on site) | 17:25 |
