Sound Muted - Unable to Switch On

The Sound Icon is with the mute setting and and clicking on it does not clear the mute, or bring up the volume bar.  When calling up the HP Support Assistant it states :
ATI High Definition Audio Device - Enabled -  Driver AtiHdmi.sys Version 5.0.7000.4
IDT High Definition Audio CODEC - Errorr (52) - stwrt64.sys Version 6.10.6276.0
Also whenn clicking on the sound icon windows says it dectects a problem, but does not offer any solution.  I have a HP Pavilion dv6 running Windows 7.   Does anybody have any ideas please?  Thanks.

The sound has been working fine, not sure when is suddenly stopped, but I have always done the HP updates when they have come up, so whether a file/driver has got corrupted then?
Try this driver. There are also previous versions available at the support page for your notebook . Look in the Driver - Audio section.

    Post the installed operating system version ( and whether it is 32 or 64-bit)
    Have you gone to the device manager to see if the sound drivers are loaded and enabled?
    Your drivers are located here. Download and install the operating system appropriate version that you have in your notebook.

  • Sony Xperia Z1 No Alarm Display and Unable to switch off alarm

    Eversince I had the first Android Kit Kat update, my Xperia Z1 C6903 was not able to hear any notification sounds, my alarm sound worked but unable to switch it off or delete it and when my contacts call me, it send it straight to voicemail and I don't even hear the notifcation call sounds either. Did a reboot and went on safe mode, I still had the same problem. Found out online that there is a sound bug with my current firmware version: 14.3.A.0.681.
    When the new update 14.3.A.0.757 was available, I downloaded it. After this, my sound notifications worked fine, however, my alarm is still not working. Both on normal and safety mode, my alarm does the following:
    1) The alarm sound works
    2) Side key behaviour does not show up on my screen, so I am not able to dismiss my alarm
    3) I manually go to my "Alarm and Clock" app and press the "OFF" indicator. Alarm sound does not stop.
    4) I have to go to > alarm settings >Delete alarms >Choose the current alarm to delete > Alarm Sound then stops.
    This has been happening eversince the Android Kit Kat version was available for download (the previous and current one). I have reboot my phone, gone on safety mode, I have gone to >Settings >APPS> All> Clock > Clear Data, and went to the Sony PC Companion > Support Zone > Repair phone/tablet, as well as deleted all my apps.
    I do not know what else to do. I can only conclude that this is an existing problem with the new software update. I need my alarm working or else I am unable to get up for my morning meetings. PLEASE HELP!

    so i have been having the exact problem on my Z1. the alrm goes off at the right time....the notification works perfectly but you just cannot switch it off or snooze it. if i go to the drop down menu the active alarm is not listed there...the side buttons dont work or have no effect even when configured.
    you literally have to power the phone off for it to stop sounding. this is really annoying and i notice that teh last comment here was a month ago and Sony have still not addressed this problem. if you google this issue there a stacks of people with the same problem and more frustarted as we keep getting suggested fixes like clear clock cache which EVERYONE knows will not work as the problem is not with the data of the alarm....its a bug in the software that prevents the app from excuting teh way it was intended to.
    my alarms worked perfectly fine before teh update was applied. ever since teh update i ahev had this problem. i dont believe that a solution is to install another alarm app from google play store. i bought the phone which advertises the alarm as a feature and if sony cannot fix or address this probelm then you have falsely advertised...
    i am a sold out sony fan...i will never purchase any other brand of phone based on my past experience with sony products but this problem is making me think otherwise. give us a proper fix for this alarm issue and dont treat us like ignorant fools with your suggessted fixes like start in safe mode or reboot your phone....that will never ever fix the problem....its just a way of avoiding the fact that you dont know what to do to fix this problem...

  • HT1349 i am unable to switch on my phone

    I am unable to switch on my Iphone 4s, can any one help

    Hello,
    I have the same question. If the iPhone 4 is any indication then please use USB 2.0 port and the new accessories to charge it. I know that this sounds obvious but I found out later :(
    Hence when you connect your iPhone to the iTunes via USB 2.0 port does it detect it? (since it should try to turn it on to sync)
    Hope this can give you a little more insight.

  • Unable to Switch Audio Sync Settings

    Hey everyone,
    I'm trying to create an animation based off of a 5-minute mp3 audio recording. I need to be able to switch my audio sync settings to Stream so that I can preview audio anywhere in my animation. Currently if I press play just anywhere in the animation it doesn't play the audio. I have to play from the beginning to hear.
    After doing some searching on the Internet, I figured out I have to switch my audio sync setting to Stream so that I can play audio anywhere in the timeline. However, the only option I have available is Event. The other ones are greyed out, as the screenshots below testify. Any help would be appreciated. Thanks!
    Hardware and Software Statistics:
    Adobe Flash Professional CC (CS6) - Version 13.1.0.226
    Windows 7 Home Premium - Version 6.1 - Build 7601: Service Pack 1
    Intel Core i7, 4GB RAM, NVIDIA GeForce GT 525M

    The first the thing a person should always do when they encounter a problem is restart their computer. No worries, I did that.
    I tried converting the file to OGG and WAV to see if it would work better. Apparently Flash Professional handles WAV fine, allowing me to switch between Stream and Event audio sync settings. That's kind of strange, because WAV files are so huge and aren't practical when developing a game or something like that.
    Thankfully, I'm just using Flash Professional to export a video, so I don't care about file size, but it's a disturbing bug.
    If anyone knows why I was unable to switch to Stream audio sync settings with MP3 files, please speak up.

    Hello Kiira Doon,
    The troubleshooting steps detailed below may help get your iPhone's display to function.
    Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
    Try turning iPhone off and then on again.
    While connected to the iPhone charger, try to reset the iPhone.
    If the low-battery screen appears, charge the iPhone.
    My issue is still not resolved. What do I do next?Contact Apple Support.

  • Unable to switch Central System Administration into Change Mode

    Hi,
    I am bit rusty on the Solution Manager - Central System Administration.
    While experimenting with my Solman system I did the following.
    1. Logged into Solman and started transaction Solution_Manager
    2. Switched to the Solution that has been configured and then followed Operations Setup->Solution Monitoring -> System Administration -> Central System Administration for <My System> (here my system is the system I wish to monitor).
    3. After following the navigation to the selected item as described in step 2, I selected the menu items Session Components->Complete.
    4. After this action of selecting the Complete session from the menu, my Central System Administration for <My System> is continuously showing Display Mode.
    I am unable to switch back the system to Change Mode.
    Am I missing something ? What needs to be done ?
    Regards,
    Siddhesh

    This was the wrong step. By setting the Session Component to "Complete", no further changes are allowed (and you receive a pop-up).
    The procedure to reopen the session component is not documented for customers. Please create a customer message on SV-SMG-MON-CSA, open the service connection and provide logon information.

    my iPhone 4 has switched off for no reason, and now I am unable to switch this on again???if anybody could help about a reboot tip , he's welcome, many thanks...

    1. On your iPhone 4 press and hold both the button and the Home button for about ten seconds. After ten seconds you should see the Apple logo showing up.
    2. Now try to run you phone again and see if it works.
    If a hard reset the still can't get the device back to a working order.
    1. Plug in the device to the cumputer and start iTunes.
    2. Press and hold the Sleep/Wake + Home for 10 seconds.
    3. Once you see the Apple Logo appears, release the power and continue to hold down the home button for about 5-10 seconds. Look iniTunes and see if your device have shows up.
    4. iTunes will notify you that you are now in Recovery mode. Click on OK to continue with the restore process.
    5. Next press and hold on the SHIFT button and click on the Restore button. Select the latest IPSW file and the prompt appears.
    6. iTunes should now attempt to get your device back to the manufacturer setting.
    7. iTunes will later give you an opportunity to restore you content from the PC. Every time when you do a sync, iTunes makes a backup so you can choose the latest backup from the sync.

  • Error sound on mac when switching tab with cmd+right arrow

    On Firefox 3.6.9 and OSX 10.6.4, when I switch to a tab to the right using cmd+right arrow, I get an error sound but Firefox successfully switches to the tab. The error sound is the same sound you get when you press a keyboard shortcut that doesn't exists (ex: cmd+?)
    However, if I use cmd+left arrow I don't get the error sound.
    How can I eliminate the error sound?

    I am just finally posting a reply. Looks as though the sound card went out. I was told that I could purchase a new open and install myself. I did not do that, but rather my step-dad just decided it was time to buy a new Mac Mini.
