[12:35] <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?
[13:16] <moosebag> some days i wish i'd never abandoned microsoft products
[13:38] <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?
[13:39] <zequence> moosebag: Which application are you trying to use with it?
[13:52] <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?
[13:53] <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
[13:54] <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
[13:55] <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.
[13:57] <moosebag> thanks for your interest; I'm at work so forgive any delays replying :)
[13:59] <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
[14:00] <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...
[14:01] <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?
[14:02] <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
[14:03] <moosebag> ok. well i struggle to understand how alsa and/or pulseaudio are supposed to interact with Jack
[14:03] <zequence> !proaudio
[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!
[14:04] <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
[14:05] <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
[14:06] <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.
[14:07] <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
[14:08] <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?
[14:09] <zequence> moosebag: jack doesn't handle leveling or any other hw controls at all
[14:10] <zequence> moosebag: you use alsa mixers for that
[14:10] <zequence> moosebag: you can try the command line tool alsamixer
[14:11] <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.
[14:12] <moosebag> do you think the AC97 controls need setting for this purpose?
[14:13] <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
[14:14] <zequence> I wouldn't worry about it, anyway
[14:15] <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.
[14:33] <moosebag> when I crack this problem, expect massive credits on the next album :)
[15:30] <moosebag> thanks again and bye, keep up the great work
[16:59] <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?
