Does not automatically select default audio playback device

***beware: do not purchase the Lenovo Thinkpad Yoga 14 - it is a lemon through and through***
Hi there - I am back again with a new problem:
The laptop does not play through my external speakers when I plug them in, even when I set the external speakers to as the default.
Sometimes, the sound does not come out of anywhere, at all.
Sometimes, it plays sound just fine.
Always a restart fixes the problem.
However, I would like to not have to RESTART THE COMPUTER every time I want something on it to work.
Anyone know a work around? Thankyou,

Open the Realtek audio control panel, click Device advanced settings, and choose classic instead of multistream.

USB-6509 Stops being recognized by Windows 7 device manager.

I am currently using a USB-6509 under Windows 7.
On a freshly formatted machine I have no trouble setting up the device using the National Insturments Measurement & Automation Software version 9.4.
Some windows updates were pushed to the computer that my USB-6509 was connected to, causing the computer to reboot in the middle of use. When the machine came back up the USB device couldn't be found by the Measurement & Automation Software, nor by Windows Device Manager. I did a complete uninstall of the software and reinstalled, this did not fix the issue. I uninstalled 9.4 and installed 9.5 and this too has not resolved the issue.
Inside device manager windows will show "Static Digital Firmware Loader" under "Data Acquistion Devices". But there is nothing installed pointing to the USB-6509.
The green light on the back has yet to come back on. I would prefer not to reformat if at all possible. Any suggestions?

I was having this exact issue. "NI Device Loader" was running on the machine, but stopping and restarting this service by itself was what finally caused the device to start working again after lots of rebooting and other troubleshooting steps. Thanks for the tip.

IPhone 3GS Not Recognized by PC, iTunes or Device Manager

I'm hoping someone can help me out here, my laptop isn't recognizing my iPhone when I plug it in, it doesn't show in iTunes and it doesn't show in Device Manager either. I've already restored my computer back almost a week, I've reinstalled iTunes, and I've stopped/started the Apple Mobile Device service, I've taken a screen shot to try and force my laptop to see it as a camera, along with whatever else I could find that pertained to my issue, and it still isn't being recognized when I plug it in. It works on another PC (an older HP laptop with the newest iTunes), I'm currently using a Sony VAIO VGN-FW480J Vista 64 with the newest iTunes installed as well. The odd thing is that when my phone was acting up the other day, it put itself in restore mode and my laptop picked it up right away as did iTunes. But when the phone is functioning properly it doesn't see it, and its only been recently that its doing this. Does anyone have any ideas as to whats causing this to happen, and how can it be resolved? Just to save the question from being asked, no the phone is not jailbroken, I did it with my 3g a year or so ago and saw no real gain out of it, so why do it to my 3GS. Thanks in advance for any and all help with the issue.

Apple Mobile Device USB Driver shows up with an ! in Device Manager (Windows 8)

When trying to sync my iPhone 5C with iTunes for Windows 8, the device is not recognised on the software. I have checked that my devices are up to date and uninstalled and reinstalled iTunes. I've uninstalled and reinstalled 'Apple Mobile Device USB Driver' in Device Manager, yet it continues to come up with an '!' next to it, and when checking the properties it states "This device cannot start. (Code 10) The specified request is not a valid operation for the target device." How do I fix this problem?

Hi, acxdunicorn.
Thank you for visiting Apple Support Communities.
If your device is not recognized by iTunes, I would recommend the steps in the article below. Start with the section labeled Verify that the Apple Mobile Device USB Driver is installed > For Windows Vista, Windows 7, and Windows 8 > If the Apple Mobile Device USB Driver is not listed.

HP Envy dv4 Windows 8- HP TrueVision HD Webcam not working or showing up in device manager

The subject is fairly self explanatory, I am using a HP Envy dv4 on Windows 8 and trying to use the 'HP TrueVision HD ' Webcam which is not working. When I went to find it in the device manager it was not present. I have restarted my computer already.
Thanks

Hey @kleinhansjy ,
Welcome to the HP Forums!
I understand the webcam in your ENVY dv4 notebook is not working.
Can you tell me if the webcam worked previously, has never worked, or stopped working after updating to Windows 8 (if the notebook did not come with Windows 8 pre-installed).
It would also help to know which exact notebook model you have. For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number?
While I await your answers please try following these troubleshooting guides:
Webcam Troubleshooting (Windows 8).
Fixing Webcam After Changing the Operating System.
Some of the steps may not apply if the webcam is not detected in Device Manager. You may need to show the hidden devices by clicking View > Show hidden devices. You might find the webcam is listed as an Unknown device in the Other devices category.
I look forward to your reply!

T440p (Windows 7) - Realtek wireless not working, repeatedly being disabled in Device Manager

Hi all,
I have a brand new T440p (type 20AN I believe) with a clean Win7 Pro SP1 install and all Windows Updates. Very soon after starting to use it, the wireless started acting strange, it would disable itself out of nowhere. In Device Manager, it shows with a yellow exclamation (it is called 2x2 11b/g/n Wireless LAN M.2 Adapter), and if I go into details, under General -> Device Status, it says "Windows has stopped this device because it has reported problems. (Code 43)"
If I right click and Disable, then re-enable, it pauses for a second, looks ok, then the Yellow ! comes back. In the Windows Event Log, it repeatedly logs Warning, Source=WLAN-AutoConfig, Event ID = 10002. The error is WLAN Extensibility Module has stopped. Module Path: C:\Windows\system32\Rtlihvs.dll
I've tried looking for a different driver, and I've uninstalled the driver from the PC completely and reinstalled, but same thing happens. The driver I have is version 2010.6.807.2013, Driver Provider is Realtek Semiconductor Corp, dated 8/7/2013. This is the same driver I found right on the Lenovo support site.
I've also tried switching the adapters on and off using F8.
I have run all necessary/relevant Lenovo updates also, from ThinkVantage Tools -> Update and Drivers. Can't recall if there was a BIOS update. I also ran sfc /scannow and it did not find any issues.
I do not have Access Connections installed. I had tried installing it to see if it made a difference, but it did not.
I found this article which seemed pretty relevant, but no help there, issues are not applicable.
Any help or advice is appreciated. Thanks in advance

Furmann,
what is the type of wireless card in your laptop? I opened a ticket with Lenovo and asked for a brand new wifi card, and they ended up sending an Intel Centrino card (forget the number, maybe 6235?) and I swapped that out, and it has been working fine ever since.

There is no bluetooth device in the device manager on my pavilion dv7 - 4065ei, does it exist?

I have a HP Pavilion dv7-4065ei on x64 Windows and I have never used the bluetooth device that is supposed to part of this laptop. I just know the specs from HP website say there is a BT device but I dont see it. I bought my laptop second hand so I dont know the original state.
I downloaded BT drivers on the official HP website (broadcom 2070) but I recieve an error during installation that sort of says there isn't any BT device on my laptop. There is no indication of any bluetooth device on this laptop even in the Device Manager.
I know there something I'm missing.
Any help please?

Suggest that you download and install AirPort Utility 5.6 for Mac OS X Lion, which is the full featured version of AirPort Utility for Lion. This version was released at the same time as AirPort Utillity 6.0.....perhaps you missed this.
If you still don't see a NAT tab...that would indicate that the AIrPort Extreme is in Bridge Mode (NAT is turned off...so there is nothing to adjust) and that NAT is being handled by another device on your network.

USB Headphones Not Always Picking Up Audio

I have Logitech USB headphones that I use with Rosetta Stone. They work just fine. They will also work if I'm watching a video that's on my computer (using the Apple "DVD Player") or when listening to iTunes.
However, they don't work for any audio that streams via the internet. For example, on websites like Hulu or if watching a video on NBC.com it won't play the audio thru the headphones. If I unplug the headphones it will play thru the MacBook's internal speakers. If I plug the headphones it it will mute the internal speakers, but no sound comes thru the headphones.
Any ideas on this?

Hi--
Thanks for responding. The USB Headset is set in system preferences for both input and output.
I went into Utilities-->Audio MIDI Setup. The USB headphones had all 3 icons next to it (finder, speaker, and microphone).
Not sure if this problem is related, but I also have a Bluetooth headset. Similar problem, works with iTunes and DVD player, but not with sound via Safari or Firefox. It has an additional problem, where my USB headset will work with Rosetta Stone, it won't respond with either audio or the microphone.
It's possible the browsers are hard wired to the Macs internal sound...
Nope, wrong, I just tried is using my RME audio interface, Firefox played a youtube video through whatever audio device I had set as default audio.
Sounds like Snow Leopard has a different Audio MIDI setup than Leopard. Under Audio MIDI setup I have both "Default Output" and "System Output" that I can use to set an audio device.
Depending on the USB device they need to be run as an aggregate device doubtful this will be of any help but you might take a look. This combines the USB audio device with the internal audio device... it's been known to help some programs "see" the USB audio,

N95 USB id not recognized if behind two levels usb...

Hi,
I spent a lot of hour, to reconnect my N95 via USB, because, explanation at the end, it seems impossible to connect the phone is there is a HUB between the N95 and the computer (else than the native buitin-the-computer).
Before everything was installed since two years. By accident equipement bluetooth have been destroyed and Windowd XP SP3 installation should have to be redone.
Even I many people that I am a professionnal in informatics, expert in some subjects, I have been lost. I pass on erratics ways, and lost hours to go to the diagnostic : mine :
The USB driver is unable to recognize a N95 (always set to the right USB connection PC-Suite or OBVI) if it is connected on a second level USB Hub.
as I have only three USB main ports I use two USB (USB2 and USB ... ) on my portable (DELL Latitude D800 and XP SP3)
During installation of PC-Suite or OVI, the soft see the "new usb device", sometimes says 'N95 master...." but never reaches to end the installation : what happends :
- the windows USB detection sees too at the same time (behind the HUB) the new USB device and propose to install it automatically, while PC-suite says "installing" (what ?).
then :
If you don't make anything this can spend as long siecles you want.
If you say OK to windows : it answers "impossible to install" and later PC-suite say "you have problems with your connection". If you disconnect you N95 you can have the "blue screen on <ousbehci.sys at address F76BE41D based at F76B7000 datestamp 433c099a>
If on windows you answer "cancel" it immediately detects "a new device" and so on... eternally. But it will create for each try an undefined device into the device manager (stopped at 32).
Some times the main N95 is detected and some others are seen but never all the link devices are detected and soft installed you are reconducted to the previous situation.
This as been repeated on clean installations (unistalling part of drivers installed)
If you connect your N95 directly on the first level of HUB it is perfectly installed.
But as my Hub are well alimented and Ucc controlled (7 disks, camera, Micro-cards reader etc...) ir is not a current alimentation problem.
Later when you reconnect your N95 is not detected if it his not connected on the first HUB level (integrated to computer)
So after this bad experience I have one advice to the others users (by security) :
- never install threw a second level HUB
- if after a good installation at a reconnect via an HUB, the 'new USB device found' main USB installer panel appears (if you change of connection this can be normal) but fails, which is not normal, connect directly your phone only on a main USB connection of your computer (and clean your device manager - XP SP3)

im having the same problem i think. When I plug my bionic into my computer nothing happens on my computer or my phone. I can't access any files from my computer. I think I may be stuck in charge only mode but I don't know how to get out of it. I have tried this on multiple computers. Anyone know how to fix this?

USB Issue - Not recognizing ANY device

I am having a problem with my USB ports.
First of all, I have a IBM Thinkpad T42 - model number 2373-9XU.
I have the latest BIOS and all the latest drivers for the USB ports.
The issue just started a couple days ago. Whenever I plug in a USB device, such as my IPod or my Smartphone, it is NOT recognized by my computer. However, any device that I plug into the USB port will start charging. So, I know there is power to the USB ports.
I have uninstalled the USB drivers and reinstalled them, still having the same issue.
Also another note, I was looking through the device manager under System Devices and there was a yellow exclamation point next to "ISAPNP Read Data Port". The error code on it was "This device cannot start. (Code 10)"
Any suggestions?
PS. I have tried to reinstall the BIOS, but when I do that it says "No update is needed at this time" and won't let me install it. Is there a workaround to that?
Message Edited by skiutah1080 on 01-27-2008 07:38 AM

So, I looked at the Services information on the Recover and Restore startup utility (pushing the AccessIBM button during startup) and found the following:
Service: upnphost
Name: Universal Plug and Play Device Host
Status: Stopped
(Previous Status: Running)
Startup: Manual/On-Demand)
Path: c:\windows\system32\svchost.exe
Vendor: Microsoft Corporation

(xpsp_sp2_rtm.040803-2158)
Could this also have something to do with the USB ports not working properly?

My new USBs are not showing up in Disk Utility

HI ! I just purchased 25 new USBs to upload biz marketing content to. The USBs are not showing up in the FInder (I've checked all the options in the Preferences Pane) nor are they showing in Disk Utility. What am I missing? Or should I just return them?

Let's clarify what you have written:
1. My usb drives seem to work with other usbs (that have been used on both mac and windows machines before - still works).
What specific USB drives are you refering to?
Are they the 25 in question?
Have you tested the USP ports on your MBP with other USB drives (not the 25) or other peripheral devices to make certain that the ports are functional?
2. I've had the usb's reformatted on a windows machine and we were able to plug it in to an old mac to see it there.
Are these the 25 USB drives in question? If so, what was the format?
3. It is only when I have returned to my office that ONLY these usbs do not work.
These are the 25 USB drives that have been formatted and are seen on the 'old mac' but do not appear on your MBP? They still do not appear in Disk Utility?
Is this a Mavericks issue? How else would it be visible on older Mac's and not my new Power PC?
It should not be a Mavericks issue
What do you mean by 'new Power PC'? Are you using a MBP or a Windows machine or is this a typo? Exactly what MBP model are you using?
Ciao.
