I stream a lot of TV on my Mac book pro and use a small portable speaker for a few hours at a time. Then when it's removed I see a small circle with a line thru it indicating I have no sound. This has just started happening in the last week. What causes t

I hope someone can help me with the above question about using a porable speaker for awhile and then being unable to have sound on my computer after I remove the speaker. I don't know how to recover the sound unless I turn off the computer...and this is frustrating when I'm receiving a Skype call ( we live overseas and receive callls fairly often). Thanks for any help on this problem. It just started a week or so ago though I've been streming TV with this speaker for several months without the problem.

Have you tried a PRAM reset?

    My iMac has started sending emails to all those in my contacts list. It's the same email friends are getting but there is nothing in my sent box. Have I got a virus (don't want to mention that word!!) or something on my Mac and how can I get rid of it?
    Thanks

  • Computer will not boot up.   a circle with a line thru it appears.

    All of a sudden my computer will not boot up and a circle with a line thru it comes up.  What is the problem and what can I do to fix it?

    Hi, master hunter. 
    The most common meaning of this symbol is that something in the operating system is damaged.  Here is the best resource when troubleshooting this behavior.

  • What does the red circle with a line thru it mean?

    I'm exhausted! Trying to find an answer to WHY iTunes won't allow me to drag a song to my iPod Nano?  It was originally an MP3; I unzipped the file; I played it in iTunes song list; it had a ! next to it; iTunes asked if it should find the file; iT found the file; the ! was removed; I played it again in iT; when I tried to drag it to my iPod, THERE WAS A RED CIRCLE WITH A LINE THRU IT????  I have yet to find--i googled and youtubed and appled til my eyes and brain and fingers ached and burned ;(--what the SYMBOL means?!?!?!?!?!?!?!?
    I have been able to download similar audio of this nature...Not sure why this one is BLOCKED?
    Thank you!

    What version of Premiere Elements are you using and on what computer operating system is it running?
    From your description "little circle with a line in it", that sound like a symbol when you are trying to do a cannot do operation.
    What exactly are you doing in your edit activities when you see this circle with a line in it? Is it at the end of the mouse cursor?
    Can you post a screenshot of it?
    If my first impression of what this is happens to be correct, then "How do I get rid of it?" answer comes from
    a. defining what you want to do
    and
    b. correcting any mis-steps you are taking in doing that
    We will be watching for your follow up.

  • How can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder which does not have firewire out/input? it comes only with a component video output, USB, HDMI and composite RCA output?

    I need to do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder (http://store.sony.co...ber=HDRAX2000/H) ..this camcorder model does not have firewire out/input ..it comes only with a component video output, USB, HDMI and composite A/V video output..
    I wonder how can I plug this camcorder to the firewire port of my laptop? Browsing on internet I found that Grass Valley Company produces this converter http://www.amazon.co...=A17MC6HOH9AVE6 ..but I am not sure -not even after checking the amazon reviews- if this device will send the video signal through firewire to my laptop, in order to live streaming properly? ..anyone in this forum could help me please?
    Thanx

    I can't broadcast with the built in iSight webcam... how would I zoom in or zoom out? or how would I pan? I've seem people doing it walking with their laptops but that's not an option for me... there's nothing wrong with my USB ports but that's neither an option to stream video because as far as I know through USB you can't connect video in apple operating systems ..you can for sure plug any video cam or photo camera through usb but as a drive to transfer data not as a live video camera...  is by firewire an old interface developed by apple that you can connect all sorts of cameras to apple computers... unfortunately my new sony HDR-AX2000 camcorder doesn't have firewire output...

    For what it's worth, you posted this in 2011, and here in 2014 I am still having this same issue. Over the last two days, I have had to unlock my apple account 8 times. I didn't get any new devices. I haven't initiated a password reset. I didn't forget my password. I set up two factor authentication and have been able to do the unlocking with the key and using a code sent to one of my devices. 
    That all works.
    It's this having to unlock my account every time I go to use any of my devices. And I have many: iMac, iPad, iPad2, iPad mini, iPhone 5s, iPod touch (daughter), and my old iPhone 4 being used as an ipod touch now.  They are all synced, and all was working just fine.
    I have initiated an incident with Apple (again) but I know they are just going to suggest I change my Apple ID. It's a simple one, and one that I am sure others think is theirs. I don't want to change it. I shouldn't have to. Apple should be able to tell me who is trying to use it, or at least from where.
    Thanks for listening,
    Melissa

  • Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book.  Cannot turn these off.  They repeat several times per session and every time computer is used.  How to diagnose this

    Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book.  Cannot turn these off.  They repeat several times per session and every time computer is used.  How to diagnose this?

    First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
    If you have more than one user account, these instructions must be carried out as an administrator.
    Launch the Console application.
    Step 1
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
    Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
    Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
    PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
    Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
    Step 2
    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

    Hi,
    Check the iChat Menu > Preferences > Video Section > Bandwidth setting.
    iChat needs to see a Minimum of 128kbps to do 1-1 chats in Video
    For 3 and 4 way chats it needs 384kbps
    Set the Bandwidth to 500kbps if it is set lower.
    Also check the speed you are getting from your Internet supplier.

    You'll have to read the terms of your warranty for India and see what your availalbe options are.
    There are plenty of service providers in India, so that's not a problem.
    Your location isn't a problem, what likely happened is your out of warranty period or you purchased the machine through another country and it got registered with a different warranty period. Once Apple discovered your in India, the warranty for that country is applied.
    For instance in the EU the warranty period is 2 years by law, so Apple has to honor that. But elsewhere it's 1 year and perhaps that's why you were denied replacement. Not because your from India, that the warranty period for machines in India is one year, like it is for everyone else.
    I guess you could fly to the EU and then make a warranty claim from there, but it's already too late, your machine and conversation with Apple was already recorded.
    Now if your indirecting asking folks here to service your machine by shipping it to the EU, you better watch yourself around here.

  • I need advice on a quality color-laser printer to work with my Mac Book Pro and my wife's Mac Book

    Hi:
    I have a Mac Book Pro and my wife a Mac Book, both with Intel Chips.
    I'm running OS 10.7.5 while she is running 10.6.8.
    Our budget is between $200 and $400,
    We would like the following features:
    1. Wireless printing over a linksys router home network. It would be very nice to have the printer in a central location without having to have it USB'd directly into the router.  Our router has a fixed location in the house and the printer will be located elsewhere in the house.
    2. Reasonably fast to fast printing (pages /minute)
    3. Color and black/white printing if the cost isn't too much higher to get color printing capability.
    4. AirPrint from iphone 5, if possible.
    5.  High quality photo printing is not a requirement......looking more for high quality document printing (Word, pdf's, etc) and printing of material from the web.
    Thanks in advance for advice!
