Audio problem with HP Notebook DV7

Hello:
I have a 4-year old HP PC laptop running Windows 7 Home Premium on 4GB Ram, 64 bit OS.
I'm not a Techie person, so please bear with me... I have been having a LOT of issues with programs like Word or Excel (and now also my IE) that give me a "Not Responding" message and almost shut down at various times. I completely cleaned my computer about three months ago by restoring it from a restore disc set that was prepared when I bought the laptop, and Best Buy assured me that doing that would restore my computer to "factory fresh" condition. However, that condition lasted just a few weeks.
Anyhow: Last week, I took the advise of a Microsoft Community advisor and cleaned my computer using Malwarebytes and then searched for Driver updates on the HP site and installed them, and my computer is behaving slightly better, but I have cmpletely lost my audio. I tried to troubleshoot this and the message said that my audio is "Not connected"...
Any suggestions?? Would GREATLY appreciate some easy-to-follow advise.
Thank you.
This question was solved.

Hi,
No problem
To answer your questions in order:
1. Hold down the power button for 30 seconds, release the button and then re-insert the battery - this procedure just dispels any residual charge from the system board which can sometimes affect connected components such as speakers ( or the audio chip ).
2. There's nothing in the procedure that will affect your current files.
Best regards,

Firewire audio problems with OS X 10.5.6

Hello,
I’m experiencing audio problems with Firewire 400 on my Macbook running Mac OSX 10.5.6.
I’ve got a 2.4Ghz IntelCore 2 Duo with 4 GB RAM and 59 GB available on the internal HD.
It’s hooked up to a brand new Mackie D.4 mixer with 2 Firewire outputs. The problems occur on both Firewire outputs.
I’ve installed automatically from the software update (which I will never do again) to 10.5.6. I never tried the D.4 with 10.5.5 so I can’t tell if the problems occur there also.
The main problem is that after a couple of minutes of recording the sound starts to break up and get really distorted. After a while the sound comes back again.
The second problem is that Soundtrack Pro or Audacity don’t get any audio input from the D.4, although audio input is clearly visible in System Preferences – Sound.
The only sound program that works with all 14 Firewire channels is Ableton, but also in Ableton the distortion occurs.
An example of the distortion can be checked here:
http://media.kaalslag.com/firewire-distortion-problem-mackieD4+Macbook.mp3
I’ve roamed several forums and sites to solve the problem and I tried these solutions:
I updated again to 10.5.6. with the full combo download from the Apple site. Restarted. Problem still there.
I shut Airport off, because lots of sites mentioned problems with Airport conflicting with audio/firewire. Didn’t work.
I did the work around with shutting the Macbook off, disconnecting the D.4, restarting the Macbook, opening Audio/Midi Setup, connecting the D.4 again, toggling the format frequencies a couple of times. Again, no use.
Right now I’m using my “old” Macbook again to record from vinyl. This one is still running on OSX 10.4.11. No problems so far.
I’ve had the distortion problems occuring before with an USB interface. Hoped that the Mackie Firewire would solve the problem, but it seems now that there’s a serious audio Firewire problem which is still not solved in OSX 10.5.
Any help, tips and/or a work around would be much appreciated. Thanks!

You could try using another computer in Target Disk mode (as an "external HD"), or you can connect the firewire cable and disconnect all other network cables (turning off airport). Then on each computer go to the "Network" system preferences and select "Built-in Firewire" from the list of ports and choose "Manually" from the drop-down menu next to "Configure". Enter the following IP addresses and subnet masks, apply the changes.
_Computer 1_
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
_Computer 2_
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
After those ip addresses are entered and you've clicked "Apply", ensure that for both computers you have file sharing enabled (done in the "Sharing" system preferences), and then check the Finder sidebar to see if the computers can see each other (their names should appear under "Shared" in the sidebar--if not, try restarting).
If the computers dont appear (even after restarting), using the "Connect To" option that's available in the Finder's "Go" menu. In there, to connect to another computer enter it's IP address as follows:
afp://IP_ADDRESS
If you're on the computer with the ip address of 192.168.1.1, you would enter 192.168.1.2 as "IP_ADDRESS". The "afp" is the protocol (just like "http" for web), and stands for "Apple Filing Protocol"...Apple's file sharing protocol.

Problem with a Pavilion dv7 - Not Booting

Hello,
I've a problem with a Pavilion dv7 wich is not booting.
When I turn on the PC the F12 key (Wireless) is fix and red and Capslock is blinking.
After search on the forum, I try several things, turn on PC without its battery, turn on without RAM module (2 module with no module, only on,...) but each time I obtain the same F12 red and Capslock Blinking continuously (1 per second).
If someone have any idea to help me I stay tuned.
Thanks In Advance,
Cyrille

Hi Visruth,
I've clean the laptop with a compressed air bomb, so i don't think it's a overheating problem.
When I take out the hard drive I obtain the same symptoms, F12 LED Orange fix and Caplock LED flashes continuously (every 2 or 3 secondes). I did not find this combination (F12 Red + Caplock Continusly blinking) ?
For the record, this is the laptop of my stepmother and I am sure she did not make BIOS update ...
Anything else to help you to make the good diag ? A tools to boot with ? A hardware test to do ?
Regards
Cyrille

USB audio problems with 2013 iMac

I'm having a strange audio problem with USB microphones and headsets. The issue with my Logitech H650e is shown in this screencast I recorded. In the first part of the screencast, I am not speaking into the mic—yet you can see the levels fluctuating as if there is static playing (not in a natural pattern that you'd see when someone is speaking). In the next part of the video I demonstrate that selecting the built-in iMac mic for input, and then re-selecting the Logitech headset temporarily solves the problem. You can see the input start to fluctuate normally as it should when I am speaking. But at 0:31 in the screencast, you can see the input levels freeze and stop registering anything. I continued to speak until the end of the screencast, but no input was detected. For this screencast, I was on a Go To Webinar call, but the problem occurs regardless of whether I'm using Skype, Go To Webinar, GarageBand or any other software.
The problem with my Blue Yeti USB microphone is also different. In that case, the input does not freeze as it does with the Logitech headset. The levels appear as you would expect, and it seems to work. However, the person on the other end can hear static in the background, even though I don't hear it in my own headphones. I learned this because I just tried to do a Skype interview with the Blue Yeti, and the interviewer told me they could hear static. We closed Skype and called each other back twice, but the problem persisted. Then, suspecting the problem was related to what I described above with the Logitech, I unplugged the Yeti and then plugged it into my Macbook Air 2013 (also running Mavericks). Lo and behold the static completely disappeared.
My Griffin iMic and Audio Technica lavalier mic (attached to the iMic) behaves similarly to the Yeti, except in this case I can hear the static when I speak with my monitoring headphones. The input works but I get a lot of cracking and static in the background. This was confirmed by calling the Skype Test Call number and recording a message, which is then played back.
Here are the facts:
All 3 of my USB audio microphones/headsets do not work with my 2013 iMac running Mavericks
All 3 of these microphones/headsets worked fine with my 2008 Mac Pro running Mountain Lion
All 3 of these microphones/headsets work fine with my 2013 Macbook Air running Mavericks
In this other thread, several people are reporting similar issues with the iMac 2013 and Mavericks. At least two people did not have the issue when the iMac 2013 was running Mountain Lion. This of course suggests the issue is the combination of the iMac 2013 and Mavericks.

Audio problems with Droid/X

When sending voice messages using Cloudtalk, the recipient hears only garbage. I contacted Cloudtalk technical support, and it appears that the 3gp file sent by the phone is not recognized. This problem is known by them, and happens only on Droid/X.
Anyone else is experiencing audio problems with the droid/x?

That doesn't sound like an audio issue with the X, it sounds like a compatibility issue between the X and the service.

Audio problems with CHS 435

Hello all, I'm having audio problems with my FiOS set top box. When I start to change channels I lose audio and can't get it back unless I turn the TV off/on or I change the HDMI source on my TV . Seems after changing a couple of channels the problem happens. I've tried the in home agent auto correct, and different HDMI cables. I have a Westinghouse TV and I'll try a firmware update for the TV and see if that fixes it. Any fix for this and the possibility that it might be the set top box ? I just got FiOS and all is going well besides this issue. Seems that the other STB that are model # 335 aren't having this problem.

Some TVs have had issues with the HDMI handshake and the Audio. You may be required to use the separate bulkier HD Component cables with separate audio cables. Or try it as a solution on that TV.
I have CHS 435 DVR on a Samsung, and 2 CHS 335s on different model Vizio TVs, all with HDMI, and no issues. Others have reported different issues. I did a search here with the following results. Perhaps this information will help.

Audio Problems with some HD channels (HBO mostly)

I'm experiencing sporadic audio problems with a handful of HD channels. Most noticably on HBO.
When the audio is output through the television itself, it sounds OK... however if the audio is output through my home theater receiver and speakers, I can hear a lot of static and "crackling" on certain movies and shows.
The issue isn't the home theater setup, as I have several other components that use it (AppleTV, Bluray, Xbox, etc.) and the audio sounds perfect from them.
The only device that displays that poor audio is the FiOS Set Top Box and even then it's only on a few channels.
I thought maybe that the optical audio cable between the set top box and the receiver may have been bad, so I replaced that. Same problem even with the new cable.
The problem is either with the Set Top Box itself or the audio levels on the stream from the channel provider.
Has anyone experienced anything similar to this, and if so... did you resolve it somehow?
Any help you could provide would be most appreciated.
Thanks!

Check the following.

You need 'HD Extra' for channels 446 - 453. I have the free 'BT Sport HD' but that does not cover entertainment HD channels. You need to subscribe to the HD Extra bolt-on for £3 for them. Have you ordered HD Extra (it only became available from last Sunday)?

Problem with HP pavillion dv7 giving message (a problem with the internal fan enter = shutdown

I am trying to identify a problem with my HP Pavillion dv7 laptop
Several months ago it started getting hot and showing messages about problems with the internal fan and battery. It would say enter = shutdown and shut off. I suspected a bad battery so I checked it without it just plugging it in with the power cable. It seemed to work better so I assumed that was the problem.
I ordered a new battery and it worked for a while. The problem came back and is getting worse. I can run it without the battery for a while but it gets got and shows the same message.
I read on here that flashing and updating the bios worked for some but the latest update gives me an error IHISI not support BIOS then Insyde flash not supported.
any help would be great this PC has a lot of info on it and I dont think it is a lost cause

Audio problem with 2gen ipod touch

Recently I've been having issues with my second generation Ipod Touch and I'm hoping that someone will be able to help me. The problem is a bit strange, so please bear with me as I try to explain it.
As I said, I have a second generation 8GB Ipod Touch that hasn't been too problematic until now. Recently it has been having major audio issues. I was listening to it with my headphones one day when the audio cut out. I thought I had paused the track by accident, but according to the screen, the audio was still playing, however the volume bar had vanished as though no headphones were connected at all. I popped the headphones out and then in again; it worked for a few moments before the problem happened again. I had thought it was just a problem with my headphones until it happened again with a different set and then the audio jack for my car stereo. All the cords are fully pushed in, I checked that problem immediately. It will randomly happen where the audio will cut out and the volume bar will vanish, like it would with nothing connected to it.
Another issue that I noticed is with my external speakers. For whatever reason they are no longer working, just like the headphones, the volume bar is gone and will not return no matter if the music is playing/paused or if I attempt to adjust it with the buttons on the side.
I have never had a real issue with this Ipod and I'd love to know if there's an explanation or if I should just attempt to take it into the Apple Store and see what they can make of it.
Thanks in advance, feel free to ask any questions and I apologize if the explanation was rubbish.

I've seen that kind of issue when there's a problem with the dock connector. It's somehow detecting something plugged into the bottom. You should try to make sure there's nothing stuck in or around the dock connector such as lint or some thing else.
Also make sure you backup and restore your ipod to make sure you take care of any software issues that may be causing this to occur.
Lastly if it still happens, you should definitely take it in for service.

Audio-Problem with Adobe Premiere Pro CC 2014 by using long Clips in AVC-Intra Codec (4Gb Border)

Hello
We own a Panasonic camera (AJ-PX5000G) and we film in 1080p50 with the AVC-Intra100 Codec. When importing longer clips in Premiere Pro, the video is fully loaded, but the waveform of the sound ends at the Time Code 00:02:28:35.
Sometimes the sound could be played after this Timecode but otherwise there is no audio. Even if we use the same clip several times we see that it works sometimes and sometimes not. It looks random.
We also tried to import the Clips with Adobe Prelude directly from the P2-Card but there are the same problems.
The Clips in 1080p50 AVC-Intra100 have a bitrate of 227Mbps. After 2 Minutes and 28 Seconds 4Gb are written on the P2-Card and the Camera starts a new picture file and 4 sound files..
It looks like Adobe Premiere Pro has problems with the correct relation of the files that all get together to one clip.
Is there anybody who can confirm this problem? Can anybody help me with this Premiere Problem?

Audio problem with one episode of iTunes tv show on two apple tvs but audio works fine on same show on iMac

I have a season pass to Dr Who and all 30+ other shows purchased on iTunes work great. Last night's episode (Hide) has a hissing sound so loud it drowns out all the audio in the show when i try to watch it on my Apple TV. I then downloaded the episode to my iMac and my iPad and no audio issues there. However when I tried playing it shared from my iMac to the Apple TV and the audio problem was there again. Same thing happened when I tried to AirPlay from my iPad to Apple TV.
I have two Apple TVs. One is latest model w latest upgrade, the other is generation before without latest upgrade. Same audio issue on both. I have tons of iTunes TV shows and movies and this is the only episode with an issue. Something is wrong with this file that causes it to screws up the audio on Apple TV.
Has anyone else seen this kind of audio issue specific to just one TV episode or movie? Anyone know support path for iTunes problems?

If other episodes play Dolby Digital fine this could be a file encoding problem - they sometimes get it wrong.
I suggest you all contact Apple about the problem via itunes store support here:

Weird audio problems with Motion when exporting quicktime videos

I have a Motion project with 2 video clips of people talking. When I create a RAM preview everything plays back fine. When I export a quicktime, the first second or so of each video clip (within the quicktime) have no audio. I've adjusted the in and out of each clip in Motion but I don't think that would make the audio disappear on export. Thinking it was just a bad export, I tried just exporting the audio and the same thing happens.
Here's what i'm using:
Mac Pro dual 3.0 Xeon
10 gigs of RAM
Motion 2.1.2

hi,
motion 2 had some odd audio problems that surfaced now and then. The only way round it was to bring the clip into FCP and edit the audio in there, and then export from fcp.
Motion 3 might have fixed this. Not sure havent had the problem for some time, since I make sure all finnishing is done in FCP.
hope this helps
