L505D-LS5001 no audio / no usb problem

i been having problems with my audio and usb drive, allready try installing drivers  and nothing..
the audio tells me no audio output installed.
and the usb and sd card slot wont work eider.  runnning windows 7 32bit , audio driver is microsoft audio highdefiniton with the yellow (!)
when i try to install laptops drivers go to the best drivers allready install.
usb problem i really dont know whats  the problem..Laptop still on warranty.
Any help please

I have run into this same issue; it seems to occur that in device manager, no USB host is even present.   Audio just has a red "X" on it.
I've tried installing the drivers, updates.
I restored from the Restore discs from Toshiba (which just crash)
I've done an install from a straight WIn7 X64 disc (which works, but then Red "X")
I've tried changing memory, HDD..
I've tried bootable LInux, which also doesn't see a USB controller.
This is very annoying.  This seems to have happened after someone flashed the 1.10 BIOS onto this (I have an L505D-LS5007)
Something here is very amiss, and a laptop with  no USB, no Audio is almost worthless.  It's as though the BIOS control for the southbridge is wrong.  I've tried re-flashing with 1.10, no difference.. I'd love to be able to rollback to 1.00, but I can't even find it.

  • Problems connecting Yamaha P-90 to GB08/Leopard via M-Audio Uno USB

    I am able to connect my Yamaha P-90 to my old G4 Powerbook running 10.3.9 using an M-Audio Uno USB MIDI interface. GB correctly detects that a new MIDI device has been added. I have just bought an 20" iMac with Leopard, but it cannot detect the MIDI device when I plug it in. The Yamaha and the interface clearly work, so I assume there must be an issue in Leopard. Do I need to install any specific drivers to make this work? I don't remember having to do this with the old machine, although admittedly it was a while ago.
    I've read numerous posts bemoaning the issues that seem to surround trying to connect Yamaha to Apple via USB. Any help would be appreciated. Many thanks, Guy

  • No audio after USB audio accessory is connected

    I've discovered what I believe is a rather interesting (and rather serious) bug in the iPhone 2.0 software:
    When an USB IAP accessory (such as a lot of newer car stereos) is connected and disconnected a couple of times the audio output from the iPhone will often stop working. Disconnecting the accessory or plugging/unplugging headphones does not fix the problem.
    And I mean the audio completely dies: I get no audio from the phone, voicemail, ringtones, iPod, or system sounds from the speaker, headphones, or dock output.
    It's like the audio drivers crash. Sometimes the audio will start working again after a long period of time (like if the phone has been sitting idle for hours while I'm at work) but usually I have to reboot to get it working. It seems when I can get audio to work again without a reboot, I get a new crashReporter log about mediaserverd the next time I sync.
    The problem occurs when the phone is connected to an iPod accessory that uses the IAP audio-over-USB capability (I tried my Pioneer car stereo and a Kenwood stereo at Best Buy) It does not occur when connected to an accessory that only uses analog audio. I've seen it happen on my iPhone 3G and the original iPhone, so I know it's not a hardware problem.
    I know for a fact the Pioneer and Kenwood units I tested are stated as having USB inputs compatible with the iPod Video, iPod Nano, iPod Classic, and iPod touch. (I can confirm the Pioneer does work fine with my old iPod Video.)
    Multiple reviews have shown them to also work well with original iPhones running 1.1.4 and below (even if you do get the "not made for iPhone" warning)
    However, both phones I tested are running 2.0. Which leads me to think this is a bad 2.0 bug.

  • Plantronics .Audio 510 USB not detected in Leopard

    Hi guys and gals
    I just updated my OS X from 10.4.9 to 10.5.1, and now I've got a bit of a problem with my Plantronics .Audio 510 USB headset. In 10.4, it would be detected automatically and work just dandy, but in 10.5, no such luck. It will not even show up in Sound in the Pref Panel. I've checked that the USB headset is receiving power, and it is. The mute button works and lights up, and the volume buttons affect OS X. The volume is turned up or down when I press them, but for the built-in speakers only.
    Any ideas?
    Thanks in advance.

    Hi guys,
    I've just bought the .Audio 510 USB myself. My system sees the headset but only as an "Unkown USB Audio Device". I can get it working, but I need to manually go in and select it in my systems settings and Skype preferences each time I plug it in.
    I also use NiceCast streaming software and it's the same deal with that. How are you guys getting on with it. Have you had any success since you last posted?

  • Mac Pro Late 2013 USB problems / freezing

    I have a quad-core CPU Mac Pro late 2013 (Model Identifier: MacPro6,1).  MacOS X 10.9.5.
    I have had all sorts of USB devices hooked up to it.  At any one time, I usually have all 4 ports filled.  I have a 3TB USB 3.0 disk that stores my large files, a USB mouse and keyboard (logitech with a usb mini dongle), a cable to charge my logitech USB cordless mouse, Lightning cable to my iPhone 5, and other things that I rotate in and out, like CF card reader, Audio Box USB audio interface from PreSonus, Sony Webcam, etc.
    About 3 months into having the Mac Pro, I noticed that my keyboard went dead in the middle of using it.  The mouse was dead too.  I blamed the RF dongle that they both share, because the Apple Magic Trackpad (bluetooth) I have still functioned.  Try as I might, I couldn't get the keyboard or mouse to work again, so I used the Magic Trackpad to restart the machine, and then my keyboard and mouse worked again.
    It wasn't until later that I realized that all the USB busses on the machine had frozen or "died" temporarily.  I realized it later because my USB hard drive complained about being "ejected improperly."
    Now I have had the USB die on the Mac Pro at least 15 times over the last month and a half.  Usually once every two days or so.
    I have tried (almost one by one) using some of the USB devices on the mac, and removing others to ascertain if it's a certain USB device that is causing this.  But the odd thing is that I never get a message from the OS like "xxx USB device is drawing too much power."
    I'm going a little nuts here because I cannot see any rhyme or reason to the USB interface lock ups.  And each time it happens, all the USB devices go dead until I restart.  Sometimes, I'm able to SSH into the machine from my iPhone and issue a "shutdown -h now" and even though I see the Mac OS X UI shutdown, it never fully halts.  I often have to hold the power button to get the machine to turn off.
    I really can't say if it's software related, hardware related or what.  I've tried to watch my workflow carefully to see if anything seems to make a pattern, but nothing yet.
    Any suggestions? Is anyone else seeing behavior like this?  Do we think it's a USB device... or is my Mac Pro flakey?
    Thanks!

    I was using a hub, so I immediately removed that upon the first issues.  But the USB has still frozen after the removal of the hub. The HD is a self powered G-Tech drive.  I'll have to play around a bit more will all of your suggestions this weekend.
    I woke up the computer just now to check the discussion, an am greeted with a notification from Mavericks that the "Disk Not Ejected Properly. (Eject disk before disconnecting or turning it off)"  which the disk is still connected, and the usb seems to still work fine.  In fact I was able to unplug the USB cable for the G-Tech HD, and then replug it in, everything reappeared fine.  The USB bus was not frozen (this time).
    But it's this kind of flakiness that has me coming and going.  I haven't (yet) been able to identify whether the USB is the problem or the driver or a third thing I haven't figured out...

  • MSI VOX Audio / Video Sinc problem

    Hi All.
    Last week i bought a VOX TV Tuner.  Nice device works well except for what i want it for.
    When I try to cpature at Full PAL DVD resolution I get audio / video sinc problems.  The audio is usually ahead of the video.  Half PAL DVD or below  it's fine.
    I suspect it is the basic design of the box that is the trouble.  Having the audio feed to the sound card rather than than in the USB2 feed has been a no no ever since the problem was discovered back in the USB 1 days.  USB2 is capable of 400Megbits..  
    However I contacted another user who has no problems and says there is a patch for Direct x PAL video capture.  Does any one know of this patch or has any one had the same problem as I have??
    This device seems so new that there is no info on the net about it..
    TIA.
    System :  P4. 2.4 Gig, 512 Meg ram, fast HDs, Direct X 9.0 (have not installed 9.0b yet) Asus Mobo P4Pe.  Matrox Mystique video card. Win 2K SP4

    I would chase that up as it sounds promising.

  • I have a m-audio producer usb microphone and since the update on Dec. 22, 2013 Logic hasn't been allowing me to record with it. Logic is reading the microphone as the input but the audio tracks don't have the record enable button. What's wrong?

    I have a m-audio producer usb microphone and since the update on Dec. 22, 2013 Logic hasn't been allowing me to record with it. Logic is reading the microphone as the input but the audio tracks don't have the record enable button and won't let me select an input for the audio track on the inspector panel. What are some possible solutions.

    Certain M-Audio USB devices (along with some other USB2 class compliant devices that don't use drivers) no longer work with Logic Pro X 10.0.5
    At this time it is unknown as to why this has happened. Nor is it known if Apple will need to fix it or if it is up to the Developers of said USB2 devices  to remedy the problem.
    In the mean time, assuming you made/could make backups prior to updating to 10.0.5.... the solution is to roll back to LPX 10.0.4...

  • High pitched noise when recording w/ M-Audio Producer USB Microphone

    hello,
    I have an M-Audio Producer USB Microphone. Recording with GarageBand, nothing else connected, using an the Apple AC power cord (three pronged ground).
    When I record with it plugged into the USB port closest to my FireWire port there is a constant high pitched noise.
    When I record with it plugged into the USB port furthest from the FireWire port there is no noise at all (as it should be).
    What's wrong with my USB port closest to the FireWire?

    I am having major problems with iMovie (and iDVD) ever since I upgraded to OS.X.10.5.6. I had to scrap my last promo-video. I am now recreating it very gingerly saving as I go but I am now stuck again. I am getting the digital audio screeching under my video clips when I extract the audio and under insert titles and transitions. Does this describe your 'crickets'?
    I have clean video and audio signal from my camcorder. Check your cam' playback to verify. After three attempts I do have clean material in iMovie but cannot proceed until I resolve this issue. I ruined my last video when I extracted the audio and ended up with a garbled rumble which I could not reverse.
    I have another question elsewhere regarding burning to DVD but I now need to resolve this before I can get to test the recommendations in the reply.
    I hope I have helped focus your symptoms. I also hope there is an answer out there for this issue.

  • Home Recording w/ AT3035 & M-Audio Mobilepre USB

    Hi All-
    I am looking for a good way to get sound from my mic (Audio Technica AT3035) into my iBook (G3, OS X.3.9, 900MHz, 256 MB RAM).
    A friend recommended the M-Audio Mobilepre USB, but I've read about people having problems w/ condenser mics.
    I realize ideally I would get a new computer and an Mbox, but that's not an option. I'm a grad student, and funds are very limited. Even the Mobilepre is stretching it.
    Any suggestions/comments?
    Thanks,
    Wes.
    iBook G3   Mac OS X (10.3.9)  

    Wes: I purchased a Behringer mic200, which is a low priced tube preamp with +48v phantom power for a condenser mic. I have been very happy with the results and features. I know that A.R.T. also makes a good one. Only problem for you is that these preamps are powered via a wall wart. Set up is via the audio input jack as opposed to usb.

  • Latency and the M-Audio mobilpre USB

    I know its like an overworked subject but I have searched and gotten no real answer.
    small but realy annoying amount of latency makes doing overdubs and such a real confusing thing. (aka-beotch).
    playback always lagging just a little behind new input(mic or instr).
    I have an M-Audio mobilpre USB and am having unacceptable latency probs.
    everything as suggested has been done.
    GB-Mobilepre-up to latest rev-driver etc...
    last try was all monitors off-only 1 track-optimized buffer for speed.
    I have a 1.2gig pros-1.62gig ram on a g4.
    could it be that its just the fact of USB as opposed to firewire?
    any guesses?
    thanx

    "be you USB or be you fire wire"
    I am using a simple setup:
    Small unpowered mixer connected to my iBook via iMic. (USB 2 connection)
    For MIDI: I have a Keystation 49e (direct USB) and a Yamaha PSR 520 connected via MIDIMAN usb 1x1.
    I do not plug my headphones into the iMic because the latency was noticeable. I only use the iMic for input. I plug the headphones into my headphone jack and turn on monitoring in each track I am recording live. The latency is barely, barely noticeable.
    You have an even better option via zero latency monitoring. If you can't get past the latency then you will have to monitor using the Mobile Pre. See your manual for details.
    I believe my performance (including latency time) has improved since running the sessions from my firewire external drive. My drive is a Lacie 160GB, 7200rpm, 8M cache firewire drive. In addition to freeing up memory on the hardrive on my iBook, the faster spinning drive seems to boost my performance as well.
    In a recent session a bass guitarist noticed annoying latency. I realized I had a cpu intensive plugin enabled. Turning the effect off removed the latency problem.
    While running Garageband make sure no other tasks are running, such as indexing. File vault is also a performance killer and I finally turned it off.

  • Anybody using M-Audio Transit USB with Front Row?

    If any of you are using Front Row with the external Transit USB D/A Coverter, and are experiencing freezing issues, you may want to read below what I have been able to figure out as to why this is happening.
    After MANY hours of frustration, I have been able to confirm that the Transit USB is causing the following problem:
    I have a Mac Mini with a clean install of Leopard 10.5.2 and all Apple updates. Nothing else is installed. With the Transit NOT connected to the Mini, I installed the latest 1.7-3 drivers from your site and restarted computer. I then connected the Transit and selected AC-3 as the Audio Output. In order to make Front Row see AC-3, you must open "DVD Player" and select its output to "Digital Out - M-Audio Transit USB" instead of "System Sound Output". You then need to restart Mini. With that done, playing movies thru "DVD Player" works fine. However, when you go to watch a movie thru "Front Row", the Transit (for some reason) causes "Front Row" to freeze. It doesn't freeze during movie playback, it freezes when hitting "Menu" and you are sitting at the Menu Screen that asks for the following 3 options: "Resume Playing", "Start from Beginning", or "DVD Menu". There is no way to get out of this frozen state. You MUST restart computer. When computer restarts, if you go into "DVD Player" Preferences and change the audio output selection back to "System Sound Output" and restart computer, this issue disappears and Front Row works fine again (however, without AC-3).
    To reiterate my point: Transit USB works fine with DVD Player but NOT with Front Row. I have confirmed this on 2 Mac Mini's.

    This is indeed an M-Audio issue. I have the same setup you do, except my mini is a 1.25GHz G4 with no on-board Digital audio output.
    To make it work with front row, you have to go to (Settings) and turn off the background music, it will stop freezing and let you select your media.
    My AC3 output from my Transit USB has never worked in this configuration. My receiver just doesn't see AC3 coming out of it.....soooo no sound at all. However I set it to (Outputs 1&2), (24bit) and boom...my receiver plays back in its Pro Logic setting via an optical connection from the Transit. All my movies and music playback just lovely. BUT. If I go on the net and try to play a flash video, like a YouTube, etc... Safari will freeze. I verified it is the Transit and not Safari because the moment I unplug the Transit, Safari wakes up, the video resumes and sound plays through the internal speaker just fine.
    Something's goofy with the M-Audio Driver for Leopard.

  • Mainstage2/air/m-audio fastrack usb/guitar no input

    I just bought MainStage 2 and downloaded to my Macbook Air (13 in) running OSX 10.7.2. Connected my guitar via m-audio fastrack usb and selected the m-audio interface for both sound input and output in system prefs. In mainstage I also made sure to select the fastrack device for input and output. Yet, when I played the guitar no input was recognized in mainstage. I could hear the raw guitar (a Taylor T5) through the earphones I had connected to the m-audio device, but nothing was making it to the computer. Same problem in garageband. I tried another guitar too, but same result. I also made sure to install the most recent m-audio fast track usb drivers.
    Any ideas? I know I've gotten the fastrack to work with garageband before with no problem (on an iMac with an older OS). I'm wondering if the problem is something about the air?
    Thanks for any help. I'm doing a live gig in a few weeks and hope to be able to use mainstage for it.
    Bob

    No sound coming out of what? Your Mac speakers, fast track connected headphone/speakers or no signal getting to garageband?

  • Garage Band : M Audio Duo USB Midi... signal in yes, audio out no

    Dug my M Audio Duo USB Midi out of the closet and trying to lay some tracks in Garage Band, but problems. I could use a hand. When attempting to record...
    - OK: Garage Band recognizes the device and I'm able to 'seemingly' record audio (from external mic via midi device)
    - NOT OK: I'm not able to 'monitor' via line out through Mac - headphones plugged into Mac (line out through midi is okay, but only picks up native signals, not tracks from Garage Band)
    - NOT OK: Also, replaying the track doesn't produce ANY sound (despite the track showing a signal)
    Any ideas? Is M Audio Duo compatible - it's pretty old piece of hardware.
    Cheers!

    First you are not using MIDI you are recording Audio that has been digitized.
    If you can't hear the playback through the interface make sure you choose the interface as your output device in garageband preferences and you have the mix knob on the interface set to the playback/return side.
    I just looked at the interface and it doesn't seem to have any mix knob try toggling the stand alone mode button.

  • M-audio omnistudio usb no longer works after upgrade to mountain lion

    hello. has anyone encountered this problem. after upgrading my intel imac to 10.8, i have discovered that my m-audio omnistudio usb is no longer recognized. i have changed the usb cable and reinstalled the last current driver for the hardware, but still nothing. would like to get it running again as that is what my studio monitors are running thru. i can't play my piano(m-audio studio 88) anymore. any suggestions would be greatly appreciated, thanks.

    It appears that ML no longer supports 32bit applications at all. 
    Therefore, you have 2 options:
    1) Use the built in VPN client, you will need your IT's help for this as it requires the group name and password of your VPN server.   You can configure it by going to System Preferences -> Network and 'adding' an VPN (Cisco IPSec) interface.   I haven't had much luck with it, it works sometimes and sometimes it fails, but other people swear by it.
    2) Move over to the Cisco AnyConnect VPN client, which does support 64bit.  This will also require your IT department as they need to configure the SSL/AnyConnect VPN on the VPN device itself.   I went to this method yesterday and it's worked out great so far.
