| Adriannom | hi. i have ubuntu studio 9.10 and two usb soundcards. when i plug one in, it appears in pulseaudio. when i plug the second one in, it does not. it doesn't matter which order i plug them in. here's /var/log/messages: http://pastebin.me/052dcc9003cca903c754e4039e098106 - any idea what's happening? | 12:53 |
|---|---|---|
| ailo | Adriannom, It's always the same device that doesn't appear? What is it called? | 12:58 |
| ailo | Two of the same kind? | 12:58 |
| Adriannom | it's not always the same device that appears, it's whatever is plugged in first ailo | 13:00 |
| Adriannom | and yes two of the same kind | 13:01 |
| ailo | Adriannom, When you say, only one appears, do you mean, you only find one of them from the devices menu in pulseaudio preferences? | 13:01 |
| ailo | How about jack=? | 13:01 |
| Adriannom | never used jack, how do i check? | 13:03 |
| ailo | Adriannom, Well, ok. If you open sound preferences, and look in the tab "hardware", you only see one device? | 13:04 |
| ailo | pulseaudio, that is | 13:04 |
| ailo | Or, are you using UBuntu Studio? | 13:04 |
| ailo | In which case it would be opening pulseaudio volume control from the menu | 13:04 |
| Adriannom | correct, only one device. i'm using studio 9.10 | 13:04 |
| Adriannom | yup, only one in volume control | 13:05 |
| ailo | Adriannom, If you do: cat /proc/asound/cards | 13:05 |
| ailo | Do you see both? | 13:05 |
| Adriannom | yup | 13:06 |
| ailo | Adriannom, They will both work with jack, then, most probably | 13:06 |
| ailo | Don't know why pulseaudio is not showing them both. What is it that you want to do with them? | 13:06 |
| ailo | Why do you want to connect two at the same time? | 13:07 |
| Adriannom | the soundcards are inside a mixer, i'm using ultramixer to send to two hardware channels | 13:07 |
| Adriannom | http://djkit.com/jb-systems/mix3-usb-mixer.html?highlight=mix%203 | 13:08 |
| Adriannom | looking at the image of the back of it should make it clear | 13:08 |
| ailo | Adriannom, Ok, so it's usb1 + usb 2 | 13:08 |
| Adriannom | hm? | 13:10 |
| Adriannom | grr, some apps are just not loading on here | 13:12 |
| Adriannom | like sound preferences :s | 13:12 |
| Adriannom | and some jack apps | 13:12 |
| ailo | Adriannom, jack apps won't load if you didn't start jack first | 13:12 |
| Adriannom | aha | 13:12 |
| Adriannom | go error messages ;) | 13:12 |
| Adriannom | so do i need to replace pulseaudio with jack? | 13:13 |
| ailo | Adriannom, I'm not sure how that device is supposed to work | 13:13 |
| ailo | Adriannom, pulseaudio is the desktop audio system. Jack is a pro audio system | 13:13 |
| ailo | You don't need to replace pulseaudio | 13:14 |
| ailo | Just start jack | 13:14 |
| ailo | You can install it by doing: sudo apt-get install qjackctl | 13:14 |
| ailo | That will install the jack control program called qjackctl and jackd, the sound server | 13:15 |
| ailo | Adriannom, But, to use two cards at the same time, that won't happen automatically | 13:15 |
| ailo | Adriannom, You would need to create a custom configuration, and I'm not sure if that can be done | 13:15 |
| Adriannom | :o | 13:16 |
| ailo | Adriannom, Still, I don't know how your device is supposed to work. 2 devices sounds a little strange | 13:16 |
| ailo | Adriannom, Try talking with people on #opensourcemusicians and #jack | 13:17 |
| ailo | There's also #alsa | 13:17 |
| Adriannom | ailo, do you know normal mixers? | 13:17 |
| ailo | Sure | 13:17 |
| ailo | Adriannom, What do you need to know? | 13:17 |
| Adriannom | it's like that except instead of just plugging audio jacks in as inputs you can plug usb cables in | 13:18 |
| Adriannom | so i can change the volumes of the music playing through each channel independantly on the hardware mixer | 13:18 |
| ailo | Well, usb cables are not like audio cables. Each needs a driver | 13:18 |
| ailo | And, for two devices to work at the same time, you need to create a common interface for them | 13:19 |
| Adriannom | correct. in computer terms the mixer just has two normal usb soundcards in it | 13:19 |
| Adriannom | well, i had another very similar mixer which worked fine like this before | 13:19 |
| Adriannom | no extra config or anything | 13:19 |
| ailo | Two usb cables, on Linux? | 13:19 |
| Adriannom | same os, i just got a new mixer cause the old one broke | 13:19 |
| Adriannom | yup | 13:20 |
| Adriannom | making 3 soundcards in total | 13:20 |
| Adriannom | (onboard included) | 13:20 |
| Adriannom | all worked fine | 13:20 |
| ailo | With pulseaudio? | 13:20 |
| Adriannom | yup | 13:20 |
| Adriannom | all appeared on pulseaudio separately | 13:20 |
| ailo | So, you are sure they are not working as one now? | 13:20 |
| Adriannom | well, maybe they are working as one, i don't know. i don't know how to check | 13:21 |
| ailo | It would sound strange to me, though | 13:21 |
| ailo | If they did | 13:21 |
| Adriannom | yeah | 13:21 |
| ailo | So, you used pulseaudio mixer to choose which card was used with which program? | 13:22 |
| Adriannom | seems i can play music out of both soundcards fine | 13:22 |
| ailo | Ah, but you use a special program, you said | 13:22 |
| ailo | Ultra mixer, right? | 13:23 |
| Adriannom | yeah, but i bet it'd work with any program, it's jsut using oss to play to the sound cards | 13:23 |
| Adriannom | i can see both soundcards fine | 13:23 |
| Adriannom | just not in the volume control, and one channel is quieter than the other | 13:23 |
| ailo | oss would be a different story all togehter | 13:23 |
| Adriannom | ah | 13:23 |
| Adriannom | oss has nothing to do with pulseaudio? | 13:24 |
| ailo | In oss you can use two cards just fine. But not with pulseaudio | 13:24 |
| ailo | pulseaudio is using alsa | 13:24 |
| Adriannom | oooh, sorry, my mistake | 13:24 |
| ailo | So, does ultra mixer not work? | 13:24 |
| Adriannom | it works | 13:24 |
| Adriannom | so i guess i could try an oss mixer | 13:24 |
| ailo | I don't know the specifics of oss. It is the oldest audio system | 13:25 |
| ailo | What else do you want to do, if ultra mixer already works? | 13:26 |
| ailo | Well, if you do have problems with pulseaudio, one way to turn pulseaudio off is to run a command like this: pasuspender -- mycommand | 13:28 |
| ailo | I think you have that on Karmic. Not sure | 13:28 |
| Adriannom | well, if i can get an oss mixer to work then there's no problem, probably best to not try to fix it any further, after all this is a production machine :p | 13:29 |
| ailo | pasuspender only suspends PA | 13:30 |
| ailo | Don't know what you are intending to use OSS for | 13:30 |
| ailo | Adriannom, I have to go, though | 13:30 |
| Adriannom | all i need to do is adjust the volumes of each soundcard because they are off | 13:31 |
| Adriannom | i'm researching that now. thanks a lot for your help :) | 13:31 |
| Adriannom | you've basically solved my problem | 13:31 |
| ailo | Adriannom, Sure. Good luck | 13:31 |
| Adriannom | later! | 13:31 |
| ailo | Adriannom, Try alsamixer, btw. Don't know if that will work | 13:32 |
| ailo | Use F6 to switch between cards | 13:32 |
| Adriannom | fixed :D | 13:32 |
| ailo | Ok. Good | 13:32 |
| Adriannom | ok i'll try that, might make it easier | 13:33 |
| Adriannom | thanks again :) | 13:33 |

| taddaaaaa | hey im trying 2 get ubs to work on vmware for test but only get the terminal | 21:45 |
| ailo | taddaaaaa, Which one did you install? | 21:46 |
| taddaaaaa | 10.10 | 21:46 |
| taddaaaaa | 64 bit | 21:46 |
| ailo | taddaaaaa, Sounds odd. | 21:47 |
| ailo | taddaaaaa, You could try 32bit. | 21:47 |
| ailo | taddaaaaa, I've had no problems | 21:47 |
| ailo | Don't try it that often, though | 21:48 |
| taddaaaaa | it's in vmware | 21:48 |
| taddaaaaa | if i have to boot interface or something?? | 21:48 |
| ailo | taddaaaaa, Actually, I've never tried wmware. Only Virtual Box | 21:49 |
| taddaaaaa | yea i just need to get into the interface | 21:49 |
| ailo | taddaaaaa, But, if there is some strange problem with the graphics, you could try recovery mode | 21:49 |
| taddaaaaa | i just get the terminal | 21:50 |
| ailo | taddaaaaa, When you boot, press down shift to get to the grub boot menyu | 21:51 |
| ailo | There, you'll find recovery mode | 21:51 |
| ailo | taddaaaaa, But, I would bet, that won't help | 21:52 |
| ailo | taddaaaaa, It works on Virtual Box for me | 21:52 |
| taddaaaaa | ill try 2 c ok babai | 21:53 |
