Audio not working / Video flashes to black every ~5 seconds

Hi. For some reason, when we turn on our TV as of late, every channel is having this issue where upon turning on, the video will flash to black every 5 seconds or so, and there is no audio. The only thing that solves the problem is unplugging and replugging in the STB (Motorola QIP7232-2).
I've replaced the HDMI cable with a new one. No dice.
Netflix via the X360 works without a hitch, so it's not the TV.
Scanning for repair/errors on the STB comes back with no issues detected.
Any reason why this is happening, and is anyone else experiencing this?

I am having the same issue. Unplugging and repowering on resolve the issue, also disconnecting and reconnecting the HDMI cable fixes it. Output from the 7232 goes to a Sony Google TV device. I also have DirecTV and never had this issue. Seems like an HDMI switching problem. Is there an easier way to reset the 7232 than just unplugging it? Or - better yet - what's the cause and how do I resolve?
Here are some troubleshooting steps you can try on your own for the problematic STB.
From your FiOS TV remote, go to:
Menu -- Customer Support -- In Home Agent -- Reboot STB
Menu -- Customer Support -- In Home Agent -- Set Top Box Auto-Correction

Youtube video not working its blank and black every browser has same problem and i have installed new flash player but same problem????help me

I don't have any real players. nothing shows when open videos it is black no error messages its black. i have clear the cookies. but no answer?????????????

You can check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in Flash 11.3 and later
*disable hardware acceleration in the Flash plugin
*http://kb.mozillazine.org/Flash#Troubleshooting
Try to disable hardware acceleration in Firefox.

NetStream.send not working in Flash Player 11.2 Beta with Cirrus, Please confirm if it is a bug

Title
NetStream.send not working in Flash Player 11.2 Beta with Cirrus, Please confirm if it is a bug or feature
Description
Problem Description:
NetStream.send can not send data to peerstreams when using with cirrus. Conflict with documents.
Sorry for tag the build as 11.0.1.3 while the bug is actually on 11.2 beta since the bug report system didn't have 11.2 beta yet.
If you are not responsible for 11.2 beta bug fix, please help a hand to handle this bug to 11.2 team.
This bug is "killing" to your application, so we really appreciate your help. Thanks.
==Publisher==
nc.connect("rtmfp://");
var ns:NetStream = new NetStream(nc, NetStream.DIRECT_CONNECTIONS);
ns.publish("sendtest");
...//after connection success.
ns.send("clientfunction", "ok"); // this line cannot reach subscribers. even if subscribers have client object correctly.
==Subscriber==
nc.connect("rtmfp://");
var ns:NetStream = new NetStream(nc, cirrusid);
var client:Object = new Object();
client.clientfunction = clientfunction; // target function
ns.client = client;
ns.play("sendtest");
Steps to Reproduce:
1. compile the code in the attachment to SendTestExample.swf (not be able to paste it here)
2. run it under flash player 11.2.202.19 beta
3. run it under flash player 11
Actual Result:
HeartBeat is:
Start HeartBeat:
send hello
send hello
send hello
which means NetStream.send was not able to call "clientfunction" as expected.
Expected Result:
Start HeartBeat:
send hello
in client function: hello
send hello
in client function: hello
send hello
in client function: hello
which can call into the clientfunction as flash player 11 did.
Any Workarounds:
I can not find it out since it's an api level bug. But this can be very important for lots of applications which rely on send to do rpc.

My ipad streaming purchased video from itunes stops every few seconds. does not happen with any other streaming video service.

my ipad streaming purchased video from itunes stops every few seconds. This does not happen with any other streaming video service. I have restarted and rebooted already.

I've tried both things, but video still stutters.. Have also tried removing profile, and complete reinstall of firefox.
I'm on 24 Mbit cable and the only user atm. IE and Chrome seems to work without stuttering.
I've having this stuttering every ~5th second, like a small "1/4 sec buffering".

Without knowing all of the specifics in your situation, you may want to try these options:
- If you have a DTA, and your remote control has a LANG button on it, press it.
- If you have an HD or SD full cable box:
Most low or no audio issues can be corrected by setting the Optimal Stereo output of the cable box. Here are the steps: Press the Menu button twice on your remote control. Select Setup. Select Audio Setup Under the Optimal Stereo setting, choose "Select to Optimize" and press OK/Select on the remote control
- The audio settings on your cable box may have accidentally been changed:
Press the Menu button twice on the Comcast Universal Remote Control. A new screen below will appear, with the top-left option automatically selected.
Use the down-arrow key (above the Info button) to navigate to Setup and press OK/Select (the center key on the remote control in the middle of the 4 arrow/directional buttons).
Use the down-arrow key (above the Info button) to navigate to Audio setup and press OK/Select.
The Default Audio Track will default to the first option–Channel default–which which is always the channel’s main audio track (unless it was previously changed).
Press the right-arrow navigation key to change the audio track. Changing this selection will instantly change the audio.
1. Press once for English
2. Press twice for Spanish (Español) OR to activate Video Description (DVS)
3. Press three times for French (Français) 4. Press four times for Portuguese (Portugues).
5. Then press the Exit button (above the Volume button) to resume program viewing
Please note: These audio options can only be heard if the program provider or cable channel is providing that additional audio option.
- If the above does not help, look at the remote control for your TV set (not your cable box) as the TVs language settings may have been accidentally changed (sometimes labeled as MTS or SAP on the remote or via your TVs settings menu).

TS3276 I can receive emails, but I cannot send emails. This just started happening. I have an iPhone and I can send emails from my phone fine. It's just not working on my Macbook. Every time I try to send an email it goes straight to my outbox. Can anyone

I can receive emails, but I cannot send emails. This just started happening. I have an iPhone and I can send emails from my phone fine. It's just not working on my Macbook. Every time I try to send an email it goes straight to my outbox. Can anyone help?

Thank you for heading me in the right direction. I reset my Mail account for Outgoing Mail Server to outbound.att.net:(customer ID)@att.net (instead of smtp.att.yahoo.com, per Apple's online troubleshooting information). I'm not sure what "(Offline)" means when it appears at the end of my Outgoing Mail Server (SMTP)?? In the Advanced box I clicked on "Use custom port: 465" and checked "Use Secure Sockets Layer." Authentication: Password; I have correct User Name and Password put in. After doing all this, when I try to send emails again today, they go directly to the Outbox and sit there.
What's curious is that my first sent email this morning did go out using the Outgoing Mail Server, smtp.att.yahoo.com: (customer ID)@att.net(Offline) but subsequent emails I tried to send with this server were rejected with the message: "Cannot send message using the server smtp.att.yahoo.com (etc.). The SMTP server doesn't support TLS(SSL) on port 587. Verify your account settings and try again." That's when I tried resetting my Outgoing Mail Server to outbound.att.net (etc.), as mentioned above, and was unsuccessful in sending out any further emails. I guess my next step is to contact my email service provider, AT&T, and see if they can help me. Thanks, again, for taking the time to respond and for giving me your input! Much appreciated!

Captivate 4 AS2 Text Entry Box not working with Flash Player 11

I am having issues with text entry boxes not working at all in flash 11. I am using Captivate 4 and exporting an AS2 swf. When you get to the slide you can type but you cannot see anything nor does the button or keystroke to move on. Also there is no cursor. Any ideas?

You said it is not working with Flash 11, so does that mean you tested with previous version and that worked?
While publishing choose Flash player as 9 and publish that, verify if that plays in a compatible web browser.
AS 2 is a legacy scripting, it has been said not too be supported with even Flash Player 10 --
http://help.adobe.com/en_US/AS2LCR/Flash_10.0/help.html?content=Part2_AS2_LangRef_1.html
I believe if you switch back to version 9 while publish your project, it should work.
Thanks,

AIR SDK 17 (BETA) is not working with Flash CS6

Hi,
The latest AIR SDK 17 is not working with Flash CS6.
I tried to publish and install an iOS app to my connected device via USB but I always get an error "Check if iTunes is installed".
The latest stable AIR SDK 16 is working fine, and yes, iTunes is installed on my PC.
DETAILS:
- Flash CS6
- AIR SDK 17
- System: Windows 8,1
- iPodTouch with iOS 8.1
REPRODUCE:
Open new AIR iOS template and publish/install it to a USB connected iOS 8.1 device.
Anyone else got that error?

I was getting this intermittently. Not a super problem. A remove and install in iTunes gets it loaded (after you tell ITunes where it is).

HT201210 AUDIO NOT WORKING PROPERLY AFTER INSTALLED IOS7

After installed ios 7
photos not able to see fully
audio not working properly.... [no treble, no depth in sound, very low soung even the volume is full]
get strucks while playing games

This board is full of people that are update crazy...
even when they have perfectly good working systems.
i know i thought well it's just a security update not a major update.
Best advice... whenever updating the OS, unplug all
firewire devices.
will take note of that from now on.
Was this auto-update? Try downloading the file and
running the update again with all firewire devices
unplugged.
While the 828 is disconnected perform the factory
reset
again.
Disconnect the firewire cable from the 828mkII
-Press the Setup knob
-Turn the Setup knob all the way to the right
-Press the Select knob
-Press the Value knob
-Power off the interface and plug the firewire cable
back
in
-Power the interface back on
i have the original 828 not mark 2, so no reset i know of, just power on off.
After the Mac updates... reboot and plugin the 828,
see if that doesn't get you going.
pancenter-
cheers pancenter, i'll give it a whirl updating without the interface plugged in. thanks for all your help.
