Problem with SB1240 USB sound card

I'm pulling hair here! I've just bought a SB240. Windows (XP Pro, SP3) detected it and I can select it fine for listening. But when I open Sound and Audio Device Properties and select Sound Recording/Volume, I see the Capture panel with the three inputs, but all the controls are greyed out and immovable. I also use the application "Total Recorder" by High Criteria, in which I can select the SB240 device but the only input line it sees is SPDIF Interface.
I'm stumped. Can anyone help?
John?

&Re: Problem with SB240 USB sound card
Thank you. I did a complete uninstall, including the device itself (from Device Manager) as well as all drivers and any SB related software. As recommended by Creative, I had previously installed the driver software from the supplied CD and that seems to have been the problem.
I let Windows re-detect the SB, but? got a "problem ... device may not work correctly.." during the detection, so I was not hopeful (this had not happened the first time I installed the device).
Nevertheless it now does work fully and is properly configured in "Total Recorder" too.
So I would suggest not using the supplied drivers and software - at least not in WinXP. But it's not very confidence inspiring.

  • UNRECONIZED PROBLEM WITH SB AUDIGY SOUND CARD

    Hi, you all. Pls help me with this problem of my SB Audigy Platinum (SB0060). In Windows XP or even Windows Vista, they can find out my sound card as an Multimedia new hard ware, but when I install sound card driver from CD (original CD driver) fail to install and a message like this: "we cannot find any support products in this computer, pls make sure that is is plugged in your computer already...". I am very disappointed with this 'cause i really like the quality of this Creative sound source. Pls help me. Thanks a lot! Pls answer me : [color="#000099">[email protected](PS: THIS CD DRIVER COMES WITH THIS SOUND CARD BOX, AND I TRY TO INSTALL A NEW FRESH WINDOWS WITH STANDING ALONE SOUND CARD WITH NO CONFLICT TO OTHER PCI CARD, STILL FAILED)

    <EM>. A friend of mine who also has this soundcard, claims he has a Decoder tab in his device controls in audiohq.. But I dont?!?</EM>
    <EM></EM>
    That is quite odd. Your Audio HQ should look like this: http://img23.echo.cx/img23/8494/hqdecode7kl.jpg. If not, then you should uninstall you drivers (using the CTZAPXX.exe app on the CD) and reinstall them.
    <EM>2. When I choose to calibrate my speakers -> basic, FL, FR, RL, RR, C plays ok BUT after that a low freq sound plays for 3 secs then my SL and SR starts to play a high freq beeps respecti'vely...</EM>
    The program does the same thing on my old T5400 and my current Cambridge MegaWorks 550. My brother has the Audigy 2 ZS also and his Logitech Z-5300s do it as well. I think the program is funky, not your speakers.
    <EM>3. Since I want to enjoy DTS, I downloaded Windvd, cofigured it to 8 channels (7.). But the SL and SR wont play anything... So I tried Windvds test and all goes well until it is SL and SR turn, they dont play anything... Almost the same as the speaker calibration app. BUT note that in the Creative THX setup console everything works well...</EM>
    <EM></EM>
    Go into the Options for your DVD software (this applies to any player, not just WinDVD) and set it to S/PDIF Passthrough. This will send the digital signal to your card, which will see it and decode it. Setting WinDVD to 7. mode will try to have the CPU decode the signal. If it doesn't work with WinDVD, then try using Media Player Classic 6.4.x.x and setting the decoder settings to Digital Passthrough. Note that you need to make sure the that decoders are enabled in the Audio HQ (for which you may need to reinstall your drivers.
    Note: DTS-ES supports 6.. Dolby Digital EX supports 7., I think.

  • A problem with ALL creative sound cards i am hav

    All creative sound cards that i've used, three i think in the past year. SB Li've, SB Audigy 2 ZS, and the Audigy 2 Zs Platinum Pro. Every time i connect speakers or headphones to the jack, i get really REALLY low sound output, also before windows loads or shuts down i hear a "bump" coming from my speakers/headphones.... I have no idea whats going on....
    Specs are:
    p4. 3.0
    DFI Lanparty 875 rev. B
    gig corsair pc4000 dual channel
    2x raptor raid 0
    SB Audigy 2 ZS Platinum Pro
    ATI Radeon x800pro
    Headphones i use are bose acoustic 2 headphones
    Speakers are logitech x-530
    If anyone has had this happen to them before or if anyone has any possible remedies for this I would really appreciate, if this doesnt help im done with creative sound cards =/
    [edit]: forgot to mention this is only for the audio jacks on the sound card itself, on the ZS platinum pro, when i connect to the jack on the hub, the sound is alrightMessage Edited by mrkuku on 06-2-2005 06:36 AM

    figured out my problem, my built in sound card drivers were conflicting with the creative drivers. Thought that if i turned off the built in sound card from bios that i wouldn't need to delete the drivers also. Thanks for any that read this and tried to figure it out. Now its working like a charm.

  • [SOLVED] Audio dropouts with USB sound card

    Hi! Recently I bought an external USB sound card (Music Fidelity V-DAC). If I plug in the USB cable the sound device is recognized by Phonon in KDE4 (kdemod).
    If I play an audio file in Amarok (or VLC) the audio is indeed redirected to the USB sound card and played correctly. However, if I use my USB mouse, or USB keyboard dropouts are occurring in the audio signal. It seems that other USB devices are interfering with my USB sound card.
    More details:
    Arch Linux with kernel 2.6.33 and kdemod 4. Phonon backend is Xine. I also tried gstreamer, but this crashes Amarok/
    $ cat /proc/asound/cards
    0 [Intel ]: HDA-Intel - HDA Intel

    I also tried an Ubuntu (9.10) live CD. Using ALSA or Pulseaudio a clean audio signal without dropouts is produced.
    I wonder if someone can help me with this problem, or point me to more information. Thanks!

    Thanks for your suggestion. I added the following line to my /etc/modprobe.d/modprobe.conf file:
    options snd-usb-audio enable_msi=1
    After a reboot the problem still persists. I also tried another suggestion from this forum:
    options snd-usb-audio nrpacks=1
    This doesn't work either. I tried to change settings in /etc/security/limits.conf, which looks like this:
    @audio - rtprio 99
    @audio - nice -10
    @audio - memlock 250000
    The USB sound card doesn't share a IRQ with another USB devices, as can be seen here:

  • USB sound card crackling when changing nr of channels in ALSA

    Hello! I have read the alsa config and some related posts from brebs (https://bbs.archlinux.org/profile.php?id=10353) and I setup upmixing to 5.1 and dmix with a USB sound card. It works, but the sound is constantly crackling. I have simplified my .asoundrc to find out where did this problem came from and I got this:
    pcm.!default {
    type plug
    slave.pcm "dmix6"
    pcm.dmix6 {
    type asym
    playback.pcm {
    type dmix
    ipc_key 567829
    slave {
    pcm "hw:0,0"
    channels 6
    It strill crackles with this config but when I change the channels to 2 there is no crackling anymore. I messed with buffer_size and period_size but the problem persists. Using surround51 does not fix it either. Thank you!
    Edit: Forgot to mention my sound card, it's a Sweex SC016.

  • USB Sound Card by default

    Hi All,
    Since i've upgraded to snow leopard i've been having an issue with my USB Sound Card. It's a Behringer U-Control UCA-202 that's connected via a Belkin 4 port hub through my Dell 2407WFP monitor to my MBP. Everytime i restart Snow Leopard automatically defaults to the Built-In Soundcard instead of my USB Sound Card by default. It's not a major issue but it's annoying having to go into the sound preference or Audio MIDI to select it. I never had this issue on Leopard and i've tried connecting the USB sound card directly to the MBP but the same thing happens on restart.
    Many Thanks,
    MuraliM

    I'm now on 10.6.1 and I still have the same problem. I select "USB Sound Codec" in Sound preferences and when i restart (with everything still connected) my Mac still reverts to the built-in sound card in my MBP. In Leopard (and even Tiger) my Mac would select the last selected sound card by default on restart and if my USB sound card wasn't connected (i.e when I'm on the move) the Built-In Sound Card would be selected. Is there something I'm doing wrong or is it what I think it is, a problem with Snow Leopard and if it is how can I make Apple aware of this problem? Now that my printer and with this soundcard problem i'm considering just reformatting and restoring my Leopard install.
    Many thanks,
    Murali

    gives absolutly nothing (I tested the HDMI output and it's fully functionnal).
    I unmuted everything that could be unmuted on alsamixer and tested varied combo of options snd_hda_intel model=XXXX (as I read that those type of card can have issue of this kind). I try to delete the /etc/asound.state file, various configuration in /etc/asound.conf. But nothing.
    In last resort, I rebooted on a F12 LiveCD and there… everything works fine ! The SPDIF output works just great, without any manipulation (with the same command as above). I tried to import the configuration of /etc/alsa, /etc/pulse and /etc/modprobe.d from this F12 LiveCD (looking if there was any special options about sound card I can just copy/paste to Archlinux) but this failed one more time.
    I really really don't see what I can do to solve this problem (and I already spend 2 entire days on this issue without any result… frustrating). So if someone's got a solution or suggestion (some configurations I can try) on this issue, any help would be greatly appreciated.

    For everyone experiencing the same problem with DG45 intel sound card (Codec: IDT 92HD73E1X5 to be accurate), the documented module is not the right one. Use model=no-jd if you want to have the SPDIF output functionnal.

  • Is Creative Sound Blaster Audigy 2 NX USB sound card compatible with Dell deskt

    Im considering buying the Creative Sound Blaster Audigy 2 NX USB sound card to use with a Dell desktop XPS 40, but recently read a forum message on another page that there was a issue with installing on a Dell Tower but no problems with installing on a laptop
    any help is appreciated if there are any compatibility issues with using this sound card on a Dell desktop, Thanks
    the main reason I would like to upgrade to this card is so my pc doesnt use the integrated audio which Id like better quality performance with a sound card and also dont want to install a internal card on the system

    joaolfb,
    Audigy 2 NX will need to be connected with the power adaptor inorder to run. USB will not be enough to sustain the power consumption of the sound card.

  • USB Sound Card won't Show in Sys. Pref. Sound Pane

    Hi, This has problem has happened occurred recently. I bought a USB Sound Card and it was working fine. I also have a USB Microphone that was working fine. (I am a DJ) I have a USB MIDI Turntable also, it works. One thing I could not get to work at all; MIDI I/O to USB adapter.
    Everything has been working, except the MIDI I/O to USB adapter. All of a sudden everything stopped working except my turntable. It all shows up in System Profiler, but not in the Sound Preference Pane in System Preferences. I don't know why they stop working all of a sudden.
    Plus one thing that I have had problems with. MIDI I/O to USB adapter does not work with any program. I bought it, it is plug and play, and it shows up in System Profiler. But it won't show up in the Audio Midi Setup.
    Any Suggestions?

    UPDATE: I got the MIDI I/O to USB adapter working. Now I just need to get the USB Microphone and USB Sound Card to work.

  • Suggest me a usb sound card for mac mini

    please suggest me a usb sound card for mac mini (i need 5.1 sound)

    The Griffin Technology FireWave will give you the 3 'cables' ("FireWave outputs six channel audio through three 1/8” (3.5mm) stereo mini-jacks: Left/Right, Center/Subwoofer and Right Surround/Left Surround.") connection for surround sound (speakers) audio. Whether or not a particular headphone set is compatible, you might ask Griffin directly about that. If you're playing a DVD with VLC or the Apple DVD Player, you will get surround sound. But, you'd have to find an MP3 with multi-channel audio inside it to play surround sound out of iTunes.

  • USB Sound Card: dual stereo output?

    I recently bought a Channel Audio Sound Card Adapter which would channel sound through my computer's USB port. Pretty standard it would allow for Stereo headphone out and microphone input:

    I opted for it so I could control from my menu bar where the sound was being directed: http://www.cnet.com/uk/how-to/how-to-quickly-change-audio-output-in-os-x/
    However I do not need the microphone in, but do need a second stereo headphone out and would like to know if:
    a) A USB adapter exists that will encompass two stereo headphone ports, not a microphone?
    b) Whether OS X will be able to distinguish the two so I can control which headphones are in use at any one time from a single USB Sound Card dongle? (note: I am not looking for a Y splitter)
    I have read of some OS X software called "SoundSource" from RogueAmoeba, but this has been retired - it would allow for me to flip the microphone port so it would transmit sound, even through the microphone socket, I might have been able to get around it like that? Is there anything else that may be available that could do the job?
    Also, I was wondering, if I had to get another USB Sound Card, could I use a USB splitter so that I could plug two USB spun cards into one port and with no loss of quality? USB ports are a premium on my computer.

    Hello,
    I'd avoid the bus powered 4 port adapter & get an AC powered 4 port hub...

    Audio Midi Setup in Utilities can do some Port aggregation.

  • USB Sound Card

    I'm looking for a USB sounds card so that I can plug my guitar and speakers into my MacBook. It's the 13 inch model so only has the one jack.
    I think it would be good to get a 5.1 usb sound card for the future as I plan on getting some 5.1 speakers. Could anyone recommend a solution thats not too expensive (under £25?).
    I saw one that also had a USB hub and ethernet adaptor in it, but i'm not sure if it worked with OS X...

    Thanks for any advice!

    Hi amck77 and welcome to the forums
    The hub you link to used to cost $130US, and I very much doubt that it would work effectively without appropriate drivers & software (which don't seem to be available for Macs) though it may still be able to perform some functions . Even people with Toshiba notebooks seem to be having trouble with under recent versions of Windows. It has now been discontinued, too, I gather.
    I'm no expert on this stuff butt might be better to focus on something like the "Maya" range for your needs (see http://www.floridamusicco.com/proddetail~prod~mayaex5ce.htm for example), or perhaps some of the "Creative Labs" gear.
