| moosebag | 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? | 12:35 |
|---|---|---|
| moosebag | some days i wish i'd never abandoned microsoft products | 13:16 |
| zequence | You're probably using alsa or pulseaudio with audacity | 13:38 |
| zequence | moosebag: If Audacity works with your sound card, you are doing something wrong with jack | 13:38 |
| zequence | moosebag: How have you determined that jack does not work? | 13:38 |
| zequence | moosebag: Which application are you trying to use with it? | 13:39 |
| moosebag | 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? | 13:52 |
| zequence | moosebag: I thought you said you saw two capture ports in your jack connections? | 13:53 |
| moosebag | yes, that's the stereo pair of capture sources | 13:53 |
| zequence | So, what are you connecting those to? | 13:53 |
| moosebag | All I want to achieve is to get Line In audio registering on a meterbridge window | 13:53 |
| moosebag | then i know it will be available for Ardour | 13:54 |
| moosebag | I've tried connecting the capture port pair to meterbridge, no luck so far. | 13:54 |
| zequence | Let me try meterbridge | 13:54 |
| moosebag | thankyou | 13:54 |
| zequence | moosebag: I would just try ardour though. | 13:55 |
| moosebag | and a SB0100 if you have one! :) | 13:55 |
| moosebag | 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. | 13:55 |
| moosebag | thanks for your interest; I'm at work so forgive any delays replying :) | 13:57 |
| zequence | moosebag: meterbridge works, but it doesn't move easily for me (the VU mode). | 13:59 |
| zequence | moosebag: I need a very high input volume for that | 13:59 |
| moosebag | 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... | 14:00 |
| zequence | moosebag: I connected the pulseaudio jack sink to it, and put a youtube video on with maximum volume | 14:01 |
| moosebag | ok thanks | 14:01 |
| zequence | The vu meter would only go to half | 14:01 |
| moosebag | hmmmm. what soundcard do you have? | 14:01 |
| zequence | I wasn't using a sound card at all right now | 14:02 |
| zequence | Just pulseaudio connected to jack, and from there to the vu | 14:02 |
| moosebag | oh ok. hmm | 14:02 |
| zequence | When you make pulseaudio use jack as the output, it becomes a jack client | 14:02 |
| moosebag | ok. well i struggle to understand how alsa and/or pulseaudio are supposed to interact with Jack | 14:03 |
| zequence | !proaudio | 14:03 |
| ubottu | For information on professional audio tools in Ubuntu, see https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro | 14:03 |
| zequence | pulseaudio uses alsa, as does jack | 14:03 |
| zequence | the drivers are actually alsa drivers | 14:03 |
| moosebag | ah the plot thickens! | 14:03 |
| moosebag | 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 |
| zequence | jack presents the card more as it is, the chip itself | 14:04 |
| moosebag | ok let's hope so. haven't tried the jack sink/source stuff yet, that's new to me since I last used Jack | 14:05 |
| zequence | 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 |
| zequence | jack only shows the channels as they are, from 1-? | 14:06 |
| moosebag | ok, interesting. | 14:06 |
| zequence | The likelihood for pulseaudio working, but not jack is very slim | 14:07 |
| zequence | Since they basically use the same drivers, where pulseaudio is the one that does more advanced things and where things can go wrong | 14:07 |
| moosebag | 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? | 14:08 |
| zequence | moosebag: jack doesn't handle leveling or any other hw controls at all | 14:09 |
| zequence | moosebag: you use alsa mixers for that | 14:10 |
| zequence | moosebag: you can try the command line tool alsamixer | 14:10 |
| moosebag | 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 |
| zequence | moosebag: It will show you all controls that exist for that card | 14:11 |
| moosebag | yes, been there a lot. | 14:11 |
| moosebag | do you think the AC97 controls need setting for this purpose? | 14:12 |
| zequence | moosebag: Sure you are not setting levels for you integrated card now? | 14:13 |
| zequence | moosebag: You choose the card with the F6 key | 14:13 |
| zequence | I wouldn't worry about it, anyway | 14:14 |
| moosebag | 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. | 14:15 |
| moosebag | when I crack this problem, expect massive credits on the next album :) | 14:33 |
| moosebag | thanks again and bye, keep up the great work | 15:30 |
| Guest95969 | 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 |
| Guest95969 | How do I do that? | 16:59 |
