=== frederickjh is now known as frederickjh_away [12:53] 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? [12:58] Adriannom, It's always the same device that doesn't appear? What is it called? [12:58] Two of the same kind? [13:00] it's not always the same device that appears, it's whatever is plugged in first ailo [13:01] and yes two of the same kind [13:01] 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] How about jack=? [13:03] never used jack, how do i check? [13:04] Adriannom, Well, ok. If you open sound preferences, and look in the tab "hardware", you only see one device? [13:04] pulseaudio, that is [13:04] Or, are you using UBuntu Studio? [13:04] In which case it would be opening pulseaudio volume control from the menu [13:04] correct, only one device. i'm using studio 9.10 [13:05] yup, only one in volume control [13:05] Adriannom, If you do: cat /proc/asound/cards [13:05] Do you see both? [13:06] yup [13:06] Adriannom, They will both work with jack, then, most probably [13:06] Don't know why pulseaudio is not showing them both. What is it that you want to do with them? [13:07] Why do you want to connect two at the same time? [13:07] the soundcards are inside a mixer, i'm using ultramixer to send to two hardware channels [13:08] http://djkit.com/jb-systems/mix3-usb-mixer.html?highlight=mix%203 [13:08] looking at the image of the back of it should make it clear [13:08] Adriannom, Ok, so it's usb1 + usb 2 [13:10] hm? [13:12] grr, some apps are just not loading on here [13:12] like sound preferences :s [13:12] and some jack apps [13:12] Adriannom, jack apps won't load if you didn't start jack first [13:12] aha [13:12] go error messages ;) [13:13] so do i need to replace pulseaudio with jack? [13:13] Adriannom, I'm not sure how that device is supposed to work [13:13] Adriannom, pulseaudio is the desktop audio system. Jack is a pro audio system [13:14] You don't need to replace pulseaudio [13:14] Just start jack [13:14] You can install it by doing: sudo apt-get install qjackctl [13:15] That will install the jack control program called qjackctl and jackd, the sound server [13:15] Adriannom, But, to use two cards at the same time, that won't happen automatically [13:15] Adriannom, You would need to create a custom configuration, and I'm not sure if that can be done [13:16] :o [13:16] Adriannom, Still, I don't know how your device is supposed to work. 2 devices sounds a little strange [13:17] Adriannom, Try talking with people on #opensourcemusicians and #jack [13:17] There's also #alsa [13:17] ailo, do you know normal mixers? [13:17] Sure [13:17] Adriannom, What do you need to know? [13:18] it's like that except instead of just plugging audio jacks in as inputs you can plug usb cables in [13:18] so i can change the volumes of the music playing through each channel independantly on the hardware mixer [13:18] Well, usb cables are not like audio cables. Each needs a driver [13:19] And, for two devices to work at the same time, you need to create a common interface for them [13:19] correct. in computer terms the mixer just has two normal usb soundcards in it [13:19] well, i had another very similar mixer which worked fine like this before [13:19] no extra config or anything [13:19] Two usb cables, on Linux? [13:19] same os, i just got a new mixer cause the old one broke [13:20] yup [13:20] making 3 soundcards in total [13:20] (onboard included) [13:20] all worked fine [13:20] With pulseaudio? [13:20] yup [13:20] all appeared on pulseaudio separately [13:20] So, you are sure they are not working as one now? [13:21] well, maybe they are working as one, i don't know. i don't know how to check [13:21] It would sound strange to me, though [13:21] If they did [13:21] yeah [13:22] So, you used pulseaudio mixer to choose which card was used with which program? [13:22] seems i can play music out of both soundcards fine [13:22] Ah, but you use a special program, you said [13:23] Ultra mixer, right? [13:23] yeah, but i bet it'd work with any program, it's jsut using oss to play to the sound cards [13:23] i can see both soundcards fine [13:23] just not in the volume control, and one channel is quieter than the other [13:23] oss would be a different story all togehter [13:23] ah [13:24] oss has nothing to do with pulseaudio? [13:24] In oss you can use two cards just fine. But not with pulseaudio [13:24] pulseaudio is using alsa [13:24] oooh, sorry, my mistake [13:24] So, does ultra mixer not work? [13:24] it works [13:24] so i guess i could try an oss mixer [13:25] I don't know the specifics of oss. It is the oldest audio system [13:26] What else do you want to do, if ultra mixer already works? [13:28] 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] I think you have that on Karmic. Not sure [13:29] 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 [13:30] pasuspender only suspends PA [13:30] Don't know what you are intending to use OSS for [13:30] Adriannom, I have to go, though [13:31] all i need to do is adjust the volumes of each soundcard because they are off [13:31] i'm researching that now. thanks a lot for your help :) [13:31] you've basically solved my problem [13:31] Adriannom, Sure. Good luck [13:31] later! [13:32] Adriannom, Try alsamixer, btw. Don't know if that will work [13:32] Use F6 to switch between cards [13:32] fixed :D [13:32] Ok. Good [13:33] ok i'll try that, might make it easier [13:33] thanks again :) === frederickjh_away is now known as frederickjh === frederickjh is now known as frederickjh_afk === frederickjh_afk is now known as frederickjh [21:45] hey im trying 2 get ubs to work on vmware for test but only get the terminal [21:46] taddaaaaa, Which one did you install? [21:46] 10.10 [21:46] 64 bit [21:47] taddaaaaa, Sounds odd. [21:47] taddaaaaa, You could try 32bit. [21:47] taddaaaaa, I've had no problems [21:48] Don't try it that often, though [21:48] it's in vmware [21:48] if i have to boot interface or something?? [21:49] taddaaaaa, Actually, I've never tried wmware. Only Virtual Box [21:49] yea i just need to get into the interface [21:49] taddaaaaa, But, if there is some strange problem with the graphics, you could try recovery mode [21:50] i just get the terminal [21:51] taddaaaaa, When you boot, press down shift to get to the grub boot menyu [21:51] There, you'll find recovery mode [21:52] taddaaaaa, But, I would bet, that won't help [21:52] taddaaaaa, It works on Virtual Box for me [21:53] ill try 2 c ok babai
