Sound has disappeared mythtv 0.20.2.20071129-1

I've just started looking into this, as we were recording the football game and when we went to watch it, there was no audio. It appears it has disappeared for all recordings after 12.26.07; I did do an upgrade that day that included the kernel, xorg-server, but I don't see anything sound or myth related. I have 2 capture cards, a pvr-350 and a pchdtv (recording analog), not sure whether on one or both. Have checked the alsa setup, looks ok. Just wanted to get this post out in case this is a known issue on the testing version of myth that I'm not aware of.
Mythbackend.log has numerous errors like this:
Error: Error getting codec params using old IVTV ioctl
NVP: Disabling Audio, params(-1,-1,-1)
NVP: Disabling Audio, params(0,-1,-1)
scheduler: Scheduled items: Scheduled 260 items in 1.9 = 0.00 match + 1.93 place

[bump]
A reboot of the system fixed the "no sound" problem, but the above errors continue to appear.

My sound has disappeared-what position should the toggle switch be in? Also my e-mails sticks a lot of the time.

My sound has disappeared - what position should the toggle switch be in? Also, my e-mail sticks a lot of the time, same old problem, no solutions.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

My sound has disappeared

The sound was working a few hours ago, then it disappeared. At the same time I noticed that songs uploaded to Itunes from my record player stopped loading part way. I have no sound at all now - not even on shut down/reboot. I also noticed this application called wbengine.exe was using all the CPU & my lap top heated up alarmingly. According to Norton 360 it is not harmful...
Any help is appreciated. Thank you!
This question was solved.

I was watching a video of a musician on YouTube and all of a sudden, there was no sound. I tried it using Chrome and had no problem. I refreshed Firefox, but still no sound. Can anyone help?

The sound on my video playback has disappeared

I recorded a few videos on my iPhone 3GS this afternoon. When I played them back they were all working. However, a little while later (not more than a few minutes), I played back one video back and the sound has disappeared! The video was of the flypast at Buckingham Palace today in honour of the Queen's Diamond Jubilee. Please help! Many thanks.

you can try doing a reset, hold down the home/power button together until you see the apple logo and then release, then wait for the phone to boot back up, then try the video again.

Headphones stop working after a certain time and the notification for sound change has disappeared

HP Pavilion dv6-6176sa
Win7 64bit.
I have a Pavilion dv6, and occasionally no sound will go through headphones when the jack is plugged in. The headphones themselves are not at fault, they are brand new and work fine.
When the headphones are plugged in, the sound will only go through the laptop speakers. I've tried updating the drivers, fiddling with the jack and socket (as I read on google), the only resolution I have found is to restart the comp, which is a bit of a pisstake in all fairness and I'd rather not do that every time it happens.
5 minutes ago I was watching a TV show, listening through the headphones, when I pulled out my USB mouse (and accidentally the charger with it). The sound then switched from the headphones to the speaker.
If I open the sound settings, it will display the headphones as being plugged in, but the sound indicator bar (thingy) will only rise and fall on the speaker icon bar.
Currently I have the audio jack pulled out about a centimetre, this allows sound through the headphones, but the sound is noticeably different to what it should be.
I had rolled it back to "High Definition Audio Device", then reinstalled it to the most current driver. This hasn't fixed it.
Also, this may be a related issue: (I guess) around the same time, the beats audio notification that pops up on screen when the volume is changed has disappeared and doesn't display when the volume has changed.
In microsoft sound control panel, it has the default speakers and the headphone logo, when i plug in the jack, a green phone circle thing appears by the headphone option, meaning it works i guess. However, the description changes from "ready" to "default communications device" and nothing changes for the regular speaker device.
When I go to >configure, and test each (L/R) speaker, if the headphones are plugged in, the noise is louder then when they're not plugged it
But yeah, brand new headphones, brand new laptop, it's mad. What's madder is that the headphones will work for x amount of time, then stop working when I next try to use them...

Can't locate email content? All of a sudden my email content has disappeared from inside MacMail? The actual emails are coming through but I am unable to view them as the area is just left blank! Nothing has been done to have changed this?

Can't locate email content? All of a sudden my email content has disappeared from inside MacMail? The actual emails are coming through but I am unable to view them in the content area! Nothing has been done to have changed this?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Hi, just updated hubby's iPhone 4 and all of his music has disappeared from the iPhone and from the iTunes library! He does have music still stored on his iPod, but can't get it from the library on his iPod back to phone or itunes. technophobe help pls!

and all of his music has disappeared from the iPhone and from the iTunes library! Luckily he does have music still stored on his iPod, but I can't get it from the library on his iPod back to the phone or to itunes.Please help, but technophobe so put it in simple english please!

Sounds like the music you had on your phone was not the same music on his computer. The iPhone/iPod touch is not designed to be a storage device. When you sync with a computer that doesn't have your music, it deletes your music from your phone.
Was this music you purchased from iTunes? if so, and you are in the US, tap on itunes app, tap updates, tap purchased and tap on the cloud icon to get each song back. If you're not int he us, get iOS5 update later this week and do the same.
But you need to move your itunes library to his computer. Create a user account on his macbook pro for you. From your external drive backup, load your itunes library on it. Then sync as usual! (Don't tell me you don't have a backup for your computer!)

My Quick launch bar at the bottom of my screen has disappeared. How do I get it back?

I was out of town for 1 day and came to use my computer and my quick launch bar has disappeared completely from the bottom of my page.

Apple menu > System Preferences > Sound > Show volume in menu bar.

The airplay icon has disappeared from my desk top. It was there two weeks ago, so I can't watch movies I've downloaded from iTunes and flick them over to my TV.

The airplay icon has disappeared from my MAC desktop. It was there two weeks ago when I successfully used it to 'flick a movie i had purchased from iTunes over to my tv. Also, if I rent the movie through iTunes, why (because of the above issue) when I go to 'Purchased' it doesn't display as an option when actually using Apple TV, it doesn't display but when I go to rent it again a message comes up saying "you have already rented this movie, do you want to rent it again"? Frustrated!!

Ok Fellas, let me give you a clue: Games, particularly those that make heavy use of graphics and sound are notoriously power hungry. In fact, when I was in the Navy many years ago, the folks working on the NTDS (Navy Tactical Data System) computers used a version of Space Invaders to load test the AN/UYK-43 computers.
I have also noticed that all of my laptops (I have a brand new Toshiba dual core, an older Toshiba single core, plus 2 Dell dual core machines) have significantly shorter battery life when I play Company of Heroes than when I am just reading e-mail or surfing the 'Net. I have also noticed the same behavior when I play games on my 4th gen Touch and my iPhone 4.
The fact is, iOS 5 did make some major improvements as well as adding some nice functionality like iMessage, wireless synch, and such, but the down side is that depending on how you use the device battery life can be shorter that what you may have experienced with pervious versions of iOS. Its just the nature of the beast...

My bought TV show has disappeared

I bought a TV show and had it uploaded onto my iPod. When I updated my iPod again it disappeared and still remained in my library (but wouldn't transfer back onto my iPod) But now the entire TV show has disappeared! Any ideas of where it could have gone?

Have you tried adjusting the "Audio Out" and the "Dolby Digital" settings in settings > audio and video? It may be worth trying several combinations of these settings, although typically it is the "Dolby Digital" setting that causes most problems for users.
If you are using a sound system/receiver, make sure that you have correctly mapped the input port on your sound system to the output, if you are unsure about how to do this, refer to the manual that came with your sound system.
Have you tried playing various content sources (i.e. podcasts, music, iTunes Store video, other video etc), do you have the same problem with all types of content? If you use optical you might also check that you can see a red light at the end of your optical audio cable. Is your optical audio cable plugged straight into your sound system, or does it go through a switch or other device?

Sound devices disappeared

I plugged in some headphones that had a microphone built into it. It made my sound preferences go wonky. My Built-In Output has disappeared on the list of devices. For a time, I had to manually control the use of headphones as an "Output" and switch back to "Input". Now I absolutely cannot get any sound. Help?!?

Do you see a red light shining out from the headphone jack? Even if you don't, try connecting a set of headphones & disconnecting them a few times - there's a switch in there that might have gotten stuck.

ITunes 11.01.1.2 - Search Bar has disappeared.

I'm running the latest version of ITunes on a Windows machine. As far as I know, we haven't updated it recently - think it has been updated for a while.
I opened ITunes this morning after using it successfully in the last couple of days and the Search Bar in the top right has disappeared, so I can't search my music collection.
I've looked under the Edit and View menus, checked Help, looked at preferences and I can't work out where it's gone or how to get it back.
Please help!
Cheers.
Don't worry - I've worked it out! Thanks all!

Hey there Man-of-Mystery,
It sounds like you are looking to use the local network sharing feature of iTunes, which can be found here:
iTunes: How to share music and video
http://support.apple.com/kb/HT2688
For the sharing feature mentioned above, you do not have to be signed in to Home Sharing and it does not require the other computers utilizing the shared library to be signed in to your Apple ID. Take care, and thanks for visiting the Apple Support Communities.

HT201335 airplay icon has disappeared everything else is the way it should be

airplay icon on my NEW ipad has disappeared how do I find it?

Airplay missing icon - I saw this fix in another forum when someone upgraded their software and ended up loosing Airplay....sounded crazy but totally worked! My airplay icon is back, and working!!
On your iPad, iPhone or iPod touch, navigate to Settings > General > International > Language and change to a different language (e.g. if you are using English, switch to French). The device will go through a language switch/reset process, and your AirPlay icon should be restored. Next navigate back to Settings > General > International > Language (translated into the new language, of course) and switch back to your original language.

My sons iPod touch has disappeared from my find my iPhone account and it can't be located in the house does this mean someone has stolen the iPod and reset it?

HI my sons iPod touch has disappeared from my find my iPhone account and it can't be located in the house is it possible someone has stolen the ipod and reset it? Please help a confused mum...

Could be. The battery could also have died or it is no longer connected to the internet
lost/stolen
No app on the iPod is required.
- If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected, on a computer browser go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone. If the iPod has been restored it will never show up or continue to show off-line.
- You can also wipe/erase the iPod and have the iPod play a sound via iCloud.
iCloud: Erase your device
iCloud: Use Lost Mode
- If not shown, then you will have to use the old fashioned way, like if you lost a wallet or purse.
- Change the passwords for all accounts used on the iPod and report to police
- There is no way to prevent someone from restoring the iPod (it erases it) using it unless you had iOS 7 on the device. With iOS 7, one has to enter the Apple ID and password to restore the device.
- Apple will do nothing without a court order
