=== ethermonk_ is now known as ethermonk [12:35] hi there. Please can anyone suggest why I can get Audacity to record my SB0100's line input, but I can't get this input into Jack? [13:16] some days i wish i'd never abandoned microsoft products [13:38] You're probably using alsa or pulseaudio with audacity [13:38] moosebag: If Audacity works with your sound card, you are doing something wrong with jack [13:38] moosebag: How have you determined that jack does not work? [13:39] moosebag: Which application are you trying to use with it? [13:52] hi again zequence. yes it could well all be my own stupidity :) IIRC, I should select Line In as a record source, and it should appear at the "capture" stereo pair on the left hand side of Jack's patchbay. Am I wrong? [13:53] moosebag: I thought you said you saw two capture ports in your jack connections? [13:53] yes, that's the stereo pair of capture sources [13:53] So, what are you connecting those to? [13:53] All I want to achieve is to get Line In audio registering on a meterbridge window [13:54] then i know it will be available for Ardour [13:54] I've tried connecting the capture port pair to meterbridge, no luck so far. [13:54] Let me try meterbridge [13:54] thankyou [13:55] moosebag: I would just try ardour though. [13:55] and a SB0100 if you have one! :) [13:55] Ardour was recording the mic input, but I want it to record Line In because I don't want an unnecessary gain stage in the audio chain. [13:57] thanks for your interest; I'm at work so forgive any delays replying :) [13:59] moosebag: meterbridge works, but it doesn't move easily for me (the VU mode). [13:59] moosebag: I need a very high input volume for that [14:00] oh! are you sure it's not crosstalk getting through? Meterbridge can be (used to be) invoked by command line to give different meter types, maybe there's a more sensitive one? PPM for example... [14:01] moosebag: I connected the pulseaudio jack sink to it, and put a youtube video on with maximum volume [14:01] ok thanks [14:01] The vu meter would only go to half [14:01] hmmmm. what soundcard do you have? [14:02] I wasn't using a sound card at all right now [14:02] Just pulseaudio connected to jack, and from there to the vu [14:02] oh ok. hmm [14:02] When you make pulseaudio use jack as the output, it becomes a jack client [14:03] ok. well i struggle to understand how alsa and/or pulseaudio are supposed to interact with Jack [14:03] !proaudio [14:03] For information on professional audio tools in Ubuntu, see https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro [14:03] pulseaudio uses alsa, as does jack [14:03] the drivers are actually alsa drivers [14:03] ah the plot thickens! [14:04] ok well i'll keep trying things when I get home, maybe see you here again, in any case I'll write up what eventually works. thanks all [14:04] jack presents the card more as it is, the chip itself [14:05] ok let's hope so. haven't tried the jack sink/source stuff yet, that's new to me since I last used Jack [14:06] pulseaudio creates inputs and outputs as stereo pair, 5.1, etc. These are also represented in the alsa card interface instructions, but jack doesn't worry about those [14:06] jack only shows the channels as they are, from 1-? [14:06] ok, interesting. [14:07] The likelihood for pulseaudio working, but not jack is very slim [14:07] Since they basically use the same drivers, where pulseaudio is the one that does more advanced things and where things can go wrong [14:08] thanks. so do you think I need to do anything with a separate mixer app to configure my SB0100, or does Jack even take care of that? [14:09] moosebag: jack doesn't handle leveling or any other hw controls at all [14:10] moosebag: you use alsa mixers for that [14:10] moosebag: you can try the command line tool alsamixer [14:11] ok, thought so. Right, so I still need to find where the line input signal is appearing in Jack, then try for a level in Ardour, assuming that meterbridge is a bit deaf! [14:11] moosebag: It will show you all controls that exist for that card [14:11] yes, been there a lot. [14:12] do you think the AC97 controls need setting for this purpose? [14:13] moosebag: Sure you are not setting levels for you integrated card now? [14:13] moosebag: You choose the card with the F6 key [14:14] I wouldn't worry about it, anyway [14:15] i don't think there 's any onboard sound system, but good point. one of the supplied mixer apps thought I was dealing with a totally different chip. The SB uses the Emu 10K1 or something like that. And cheers for the F6 suggestion. [14:33] when I crack this problem, expect massive credits on the next album :) [15:30] thanks again and bye, keep up the great work [16:59] I am using Ubuntu Studio on my desktop. I have a Sony Xperia SP. I want to backup the information onto the desktop so I can do a factory reset on my Xperia without losing data. [16:59] How do I do that?
