Soundblaster Live! 24-bit USB External Setup

REW (SB Live! 24-bit external)

Hi,

I have a Creative 24 bit external soundcard but have been unable to calibrate it despite messing with all the various settings there was always some feedback. The only way I can get a normal looking curve was to use the internal card as output and the external card as input. This gave me a calibration curve similar to that for an internal card.
I then tried a sweep for the sub but it seems with limited success :scratch:
I've spent all day on this and achieving very little so far. Can anyone help?

Cheers.

Thanks. I think the main problem is that I am not reading the help file directions completely and carefully.:rolleyesno:

PLEASE, I am looking for anyone that can help me enable the "Enable Monitoring" feature in Vista OS with the 24-Bit SB Live system. The feature that was available in XP and earlier is no longer there and I can't figure it out.

Thanks
Attention Vista Users

There are new Soundblaster Live 24-bit USB external sound card drivers dated August 23, 2007 for computers using the Vista operating system available here

http://us.creative.com/support/down...&driverlang=1033&OS=26&drivertype=0&x=28&y=14

Special attention should be paid to the instructions about uninstalling your previous driver.


What does it fix?
This resolves button functionality issues for Sound Blaster Audigy 2 NX, Sound Blaster Live! 24-bit External, Sound Blaster Surround 5.1 and Sound Blaster Digital Music SX
Removes distortion found in the recorded file when selecting Wave, MIDI or CD as your recording source

It has been quite a few months since you described that new drivers were available dated Aug, 23, 2007.
Did these drivers fix the issues with REW use under Vista? (I will probably be purchasing this sound-card, since it seems to be well supported with REW, and my newest laptop runs Vista.)

Did the newest driver resolve the issues with the differences in controls available that you described in the post you made back on 6/13/2007.

Can I use my optical out into the receiver instead of my line out? When I use the line out I get a 58dB loud crackling and whining noise where as if I use the optical connection it is dead silence. I don't see not much difference in my test results and there is not much difference for volume level but I don't have to listen to the noise. I have left output and input looped for reference and I loaded the mic calibration file. I checked the scope and it looks good still. Is that an acceptable connection?

Generally we don't recommend using the digital output of the soundcard, since you aren't able to accurately create and use a soundcard calibration file. Using the new alternate method of the left channel calibrate cable isn't a good idea either, since it will compensate for the soundcards analog driver section that you aren't using.

It would be better in my opinion to use no left channel calibrate and no soundcard calibration file. It won't be as accurate as using the analog output and input, but if it's a decent card and you assume the digital response is good, then go ahead.

I would try and get the analog working. No reason it shouldn't be fine....

It looks more like what I was used to seeing and is at reference level again since getting the new card. :whew: I will use the analog. Looks like this right now with my ceiling partially open while I am trying to figure out what to put in it etc.



Thank you

Hi,

I'm trying to use the SoundBlaster Live 24bit USB card with REW, but it doesn't seem to be working. Whenever I select it in REW's settings under "input device and input", I get the following error message:

Unable to access the selected device
javax.sound.sampled.LineUnavailableException: Line-In/Mic-In (Sound Blaster Live! 24-bit External) does not have any lines supporting PCM_SIGNED 48000.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian

Same thing if I leave it to "default device". Does anyone have any clue as to what is going on? I purchased this sound card specifically because the REW Help claimed that it works. I've tried it on my Macbook (running 10.4 Tiger) and on my Vista PC and I get the same issue with both computers. Thanks.

I believe that the Help files are fairly specific that it doesn't work with VISTA, where it says:

Note that the Creative software does not function properly under Windows Vista, the card can still be used but only by loading the Vista-compatible drivers from Creative's website and using the Windows mixer, do not install the Creative software under Vista..

With respect to the Mac, I believe that Leopard OS has proved to work better with this card.

brucek
Thanks, I appreciate the response. When it said it doesn't function properly on Vista, I didn't know if that meant the included CD or something else. My dad's laptop has Leopard, so I'll see if it works with that. It also has XP, so it's bound to work SOMEHOW! Thanks again :).
I believe with the new creative drivers and the new software, as of March 11 2008. the software works under VISTA, can any one confirm this.
You're right. I got things to work today just fine - had one of those "DUH!" moments regarding my SPL meter I was using as a microphone. Everything works fine on my Vista PC.

Interesting.

So, in the Settings page, do you see the SoundBlaster card in the Output Device and Input Device selection pulldowns? Previously, REW had no access to the card and Default had to be chosen.

If you are indeed able to select the SoundBlaster card now, then is the Wave Volume and Output Volume and Input Volume not grayed out anymore? Do you have control of these parameters in VISTA?

Would you mind posting some instructions for those of us not quite at the DUH! stage? I can't find a way to turn the monitor off to prevent feedback. I'm using Vista on a Toshiba laptop.

Thanks,
Doug

Well, things aren't great, but I got an input signal. I do get to choose the SoundBlaster card in the Output and Input device pulldowns. However, Wave Volume, Output Volume, and Input Volume are grayed out.

Here's my current issue. When calibrating my sound card, I cant get the output and input any closer together than about 8dB. That's way too far off to be making accurate measurements. I've maxed the input for the SoundBlaster, and maxed the output as well, as REW suggests when you can't adjust with REW itself, but I'm seeing about 8dB of separation. Any suggestions?

Edit: the input volume is too low and can't get high enough in relation to the output volume.

I don't see a real problem there. I might suggest to simply use the left channel calibrate method and then you don't go through the soundcard cal routine.

Connect a cable on both left and right channels with the left channel calibrate checkbox ticked and take a measure and see if you get a nice flat line...

brucek
Ok I'll try that right now and I'll let you know what happens in a few minutes :)
Ok, I just calibrated it and it seemed to work fine. Here's a link to a picture of the calibration. Please tell me if it looks ok. Thanks :).

:). Thanks for your help, Bruce. Looks like the SB Live! 24 USB works with Vista. Incidentally, I installed the drivers on the CD that came with the card and updated the drivers, but ended up deleting them all from my PC. Creative's "Vista" drivers might actually cause problems. I don't know that for a fact, but just thought I'd let everyone know that this is without Creative's drivers.
