No sound through browser upon wake

I've been posting this question, but nothing helpful. It is SO frustrating to have no sound when visiting a website after the computer has been in sleep mode. I may have a dozen browser tabs open, but I have to close the browser and reopen it to immediately get sound back. It's very consistent. Surely Apple is aware f this and must be able to provide a solution?
I am using google chrome (horrors) as browser. I HAVE NOT been using Safari so don't know if it also happens with that, but I'll bet it does.
I'm using the most current OSX on a late 202

Sometimes computers have minds of their own, they decide to change something that has worked perfectly for years, and then stymie us. Resetting the SMU is not that simple, it's just one of a number of things one can do to deal with a recalcitrant machine, and I'm sure you would have arrived at it on your own, after all, you had already tried several other things.
Anyway, glad that the problem has resolved, and happy that I was able to help,
Miriam

  • No Sound through HDMI - Mac Mini

    Hello Forum, New user to this forum, I have a problem, I have bought Mac Mini ( August,2010) for home use and recently bought LG -32LD450 - 32". I have connected my TV directly to Mac Mini using a 1.3X HDMI cable. I have video/ display - however no sound. All i can hear is sound from the Mac Mini's internal speaker. I tried to change the setting through - System preference/sound/output. It displays - LG / HDMI - however i cannot select, the setting is active with internal speakers only. Please advise how i can obtain audio from the TV.
    I forgot to mention the message seen in System Preference/Sound/Output - LG TV HDMI - Settings for the Selected Device : The Selected Device has no output controls.
    In addition to the above, i have tried to check the output controls through Utilities/Audio Midi Setup. Here too i am not in a position to alter HDMI Settings.
    Help in this regards is highly appreciated...thanks
    Please help

    Krusdublin: I am experiencing similar issues with no real solution yet:
    I have a Mac Mini 2010 connected to a Sony Bravia HD TV via an HDMI cable
    sound output via TV speakers was not working when I first connected the two (about 4 mos ago)
    couldn't figure it out- and just used an headphone cable to connect the mac mini to a stereo
    somewhere between then and a month ago I disconnected all incl. power, and reconnected as I had to re-setup my tv (all reconnected in the same outlets via HDMI) (also got rid of the stereo at this point)
    then about a month ago I was back in the Sound preferences and found that I was able to get audio output via the TV speakers.
    about a week or so ago I disconnected all incl. power, and reconnected as I had to re-setup my tv (all reconnected in the same outlets via HDMI)
    however, about 3 days ago, sound output via TV was no longer an option
    when I say it is not an option, I have two lines under name and types as follows:
    "Internal Speakers" > "Built-In Output"
    "SONY TV" > "HDMI"
    when I switch from internal speakers to HDMI, I notice that the sound volume bar at the bottom of the screen goes faint, and I can't adjust the volume using the sound keys on my keyboard (bluetooth)
    the speaker icon in the top right of the screen is also greyed-out and not changeable...
    I notice that when I switch input on my TV aerial to the MacMini (HDMI 1) I get a little yellow triangle with exclamation mark in it, and the text: "AUDIO only" at the bottom right of the tv screen. (In not sure if I had this before or not - dont completely remember seeing it, but vaguely do...)
    I've also updated my macmini whenever an update is released (within a few days)...
    I've spoken with an Apple tech over the phone and went through a number of reboot (while holding down certain keys, etc.) to no avail. She then recommended that I go into the Apple store and have the mini checked out....
    At the apple store, the apple tech took the machine to the back, out of sight, and returned about 20 mins later to say that it was working fine. I asked to have it hooked up to one on display - so I could see for myself. We hooked it up to an HDTV via HDMI and booted up. Went to System Preferences > Sound and selected: "Panasonic TV" as the output device. I still could not adjust the volume bar (it went greyed out) - but I could crank up the tv volume directly and get sound. Great! Sort of... While now I could get sound - it was not the same as before where I could control the sound through the mac - only directly through the TV. The Apple guy said that he didn't know what I was talking about - and said that they way the machine was now working was the proper way. He unhooked my mac mini, and gave it to me, and walked away.
    Frustrated, I walked down to the Sony Store to try out the mac mini there. Same result as in the Apple store. I could control sound directly via the TV, but not through the mac mini controls.
    Took the mac mini home, reconnected everything and now get sound through the TV - but I cant control it with the mac mini on-screen controls, nor the volume buttons on the mac blue tooth keyboard.
    Today, I was watching a movie via itunes, hit pause, and went to do something for a few minutes. When I returned, the TV indicated 'no signal' via the HDMI (I assume because the mini went to sleep.) Tried to wake the mini - but couldn't. Had to resort to pressing the button at the back. When the mini came back, I had no sound at all coming through the TV speakers, even though the sound preferences settings were still the same. I had to resort to shutting down the mac mini, and then unplugging the power on the mini for a few minutes. Powering back up, sound was again able to comefromt eh mac through the TV speakers - but still could not control sound using the mac mini controls.......
    Thats where Im at so far....
    Aarrgh.
    THOUGHTS?
    Thanks in advance,

  • 10.4.10 - no sound in browser

    Hi guys,
    Since updating to 10.4.10 (Power PC) I can no longer get any sound through my web browser (neither Firefox nor Safari - both latest versions).
    I've heard of people having sound 'popping' problems but not a complete lack of sound. For instance, Youtube videos etc have no sound, nor do websites that are supposed to have sound.
    Apart from that, software such as iTunes works fine.
    Is anyone else experiencing this or can offer any advice?
    Many thanks,
    Rick

    I tried both your suggestions but still no change.
    The 10.4.10 update has definitely increased my Mac's maximum sound output. It's now a lot louder than it used to be, but at the expense of killing sound in my browser

  • HT1338 no sound through hdmi after sleep mode

    I have no sound through the hdmi cable after mac mini wakes up after sleep mode but I do have sound when I resart my mac although Im unable to ajust the volume and the sound icon at the top bar is greyed out..system preferences says the selected device has no output controls for this device and the slider bar it also greyed out..

    If you don't already have a current backup, back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

  • No Sound through amp when viewing content onlineon my 55L7200U only on TV Speakers

    When ever I view video clips through the browser on my TV there is no sound that is sent back to my AMP. I can only get sound out of the built in speakers on the TV. Is this normal or should I be able to hear the sound through the sound system tha is hooked up to the TV. All other attchements, Blu Ray, Game console etc work through the amp just the TV does not.

    Is it on specific content? Have you tried rebooting all devices and making sure they are up to date?

  • Connecting MacBook to Sony Bravia KDL-40XBR9 - No sound through TV

    I recently bought a Sony Bravia KDL-40XBR9. I have it hooked up to my MacBook using an HDMI to DVI connection. But, I'm not getting sound through the TV. So, I bought a 3.5mm to RCA (one red, one white connection) cable. I've plugged the red and white connections into all of the red/white ports on the back of the tv but I'm still not getting sound out of the tv.
    Can someone please help me with this setup?
    Thanks!!

    Does your Bravia also have red and white input jacks on the side of the TV (my Bravia does, on the left). On my Bravia, those are the only audio inputs that are active for all inputs, and they are what I use when I am playing my MB through HDMI (which, as you found, only transmits video).

  • Hi i upgrade from lion to mountain lion to day on my mini mac,Since the upgrade i am getting no sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever

    Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
    I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.

    Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.

  • High memory use when checking downloads folder through browser

    High memory use when checking downloads folder through browser.
    I have a total of 3 DDR2 Gbytes of ram. Pentium(R) Dual-Core CPU T4500 @ 2.30GHz Win 7 home pr. 64bit. Firefox 27.0 beta
    I right click on a file to "open containing folder" from the drop down menu in downloads.
    When the folder has been opened, explorer is trying to index the folder (which it never does completely or well after 5 minutes I close the folder and shut down the dllhost process cause laptop is blazing hot) and memory keeps increasing till no more is available.
    I checked task manager and see that dllhost is the particular process that is causing the spike in memory usage even after closing the folder I right click and stop the process and memory is restored after awhile.

  • Sound through hdmi to my tv works but not when watching video online like 4OD

    the sound through hdmi to my tv works with music and videos I have downloaded, but not when watching video online like 4OD and youtube.
    How can I get it to work?

    Ok so I happened to figure it out while on the phone to apple support. Even though the guy was very nice, I think I knew more than him! He was explaining very basic resolution principles I played about. I had the second option in displays resolution. All I did was unplug the HDMI cable, click on 'best for display' then plugged the HDMI in and my resolution on the normal monitor changed to the normal blue, then went black momentarily and then changed to a strange resolution but another window appeared that said SONY BRAVIA HDMI at the top! Hey presto! Don't know why it didn't do it yesterday - I probably left the HDMI cable in or something! Oh well. Problem solved!

  • 5g nano no longer plays sound through (any) dock!?

    I recently got a brand new dock, and it is, without a doubt compatible, with the 5G nano.
    It played out loud through the dock with no problems for a few weeks, but it suddenly stopped transferring the sound through to the dock the other day, and instead, now, it just plays through the external speaker on the actual iPod. I tried it through my friend's dock too, and the same thing happened.
    This is all to do with the internal connection, because when it first happened, I found that if i wiggled it around in the dock and held it at a certain angle, it played. However, that only lasted a few minutes and then it just stopped playing through the dock altogether.
    It's strange because it connects to the computer fine through the exact same slot, and I can transfer music fine.
    Saying that...on the day ot happened, the song I had just transferred from the comp onto the iPod magically disappeared from the device. That was weird. So I had to put it on again. And it definately went on the first time; I saw it in the playlist.
    Anyway, all I can think of is that I have 'dislodged' something inside the iPod when connecting it into to the dock, or i've 'pushed something out of place internally' maybe...because I have not been using the dock adaptor (the iPod doesn't fit inside the adaptor because it has a plastic case over it). So maybe i've pushed it too far down into the dock slot or something?
    Can anyone tell me if they've had this problem too?
    Or if so, how much would this kind of thing cost to get repaired? Or have I mucked it up so bad I may as well give up now and get a new one (unless I never want to use a dock again)?

    I just purchased my 30gb video iPod, and am running into almost the exact same situation. The only difference is that I don't have to reset it. It just won't play a movie at all. It starts the little "timer" thing that clicks around, but then goes back out of the movie. I know the movie is a good download, because I can watch it from start to finish within iTunes.
    Anyone got any ideas? I really don't want to stay on hold for 1-2 hours waiting on a person to talk to with tech support!

  • Ipod touch no longer charges with USB nor does it output sound through the connector

    2 problems after the latest iOS update:
    (1) my 3rd generation iPod Touch no longer changes when connected to the computer through the USB connection.  It says that the device is not supported for connection through USB.  My computer is running Snow Leopard and all software is up to date.
    (2) it also does not output sound through my clock radio nor through the built-in ipod connection in my MINI. 
    This all worked great until the latest iOS update.  Something broke in the latest update.
    anyone else seeing this issue?

    You can try the standard fixes:
    - Reset. Nothing is lost
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup
    - Restore to factory defaults/new iPod.
    If still problem then the iOS broke full compatibility. you have to then wait for either Apple to fix the problem in an iOS update or for Honda to fix it via a firmware update/
    Have you contacted Honda?

  • No sound through headphones/microphone ALC892

    I've been trying for days to fix this issue, and am lost.  I've got a new desktop and cannot get sound to come out my headphones, or take input from my microphone.  I believe my sound card driver is installed correctly, and that it is a pulseaudio problem.  I've gone through the troubleshooter on Arch's alsa, and pulseaudio wiki pages.  I do get sound through my monitor speakers when I use HDMI, but would prefer headphones.  I have tried Debian, Linux Mint, Manjaro, and crunchbang and none of them have had working audio for me. 
    where I see a problem is in pavucontrol, all my profiles, and input/output devices say (unplugged).  So in output devices, and next to Headphones it says (unplugged) when it is plugged in, same with my mic.  i see the visualizer playing to the music under headphones though.
    everything is unmuted in alsamixer.
    I've tried both the front panel mic/headphone port, and the back panel.
    thanks in advance.
    EDIT: i did get sound to play through my roommates USB headset, they have there own sound card. So sound does work, but I cannot always use these and still want to get sound through my headphones/mic.

    Perhaps you have previous configuration files on your system (~/.asoundrc or similar)? You might want to look at you mapping of signal paths/jacks with hdajackretask found in alsa-tools (Frontpanel might be inactive on your particular hardware setup). Double check if correct module model is loaded for your card (line 36).
    If you kill pulseaudio, does aplay produce sound?
    To unload jack detection module this should work:
    pacmd unload-module module-switch-on-port-available
    Some people have issues with pulseaudio since upgrade to 5.0, so checkout changelog for configuration changes, here in forum there are several topics on this matter.

  • MacBook Pro loses wifi connection upon wake since I bought a new AirPort Express

    Hi. I've been using Apple devices and computers since february 2008 and had no problems until now. I currently own an early 2011 13" MacBook Pro and a PC running Windows 7 and Ubuntu 12.10. Until early February, I used a 2nd gen AirPort Extreme to connect to wifi upstairs, being connected via Ethernet to my ISP's modem located downstairs which provides a weak wifi signal (of course my ISP says it's impossible since their modem is the best on the market), not even compatible with Apple's wifi systems (all other French ISPs modems are compatible with it), that's why I had to get a 30 ft ethernet cable running down the stairs. My connection was lost everytime I went upstairs/downstairs so I bought a new Airport Express to replace my ISP's modem wifi signal and I'm using my AirPort Extreme to extend the wifi network upstairs. Now all my devices and computers have a strong wifi signal anywhere in my house with only one downside: My MacBook Pro (and only it) loses the wifi connection upon wake after sleep and I have to disconnect/reconnect it manually. I didn't bother installing Windows on it as I removed the Superdrive to setup a DIY Fusion Drive a few months ago so I can no longer boot optical medias and I can't know if it's a hardware or software problem. Again, everything was working all right on it until I changed my Wifi network configuration a month ago when I bought my Airport Express.
    Can anyone help me ?
    Thanks in advance.

    Well this isn't making sence. 
    What is the model # on your extreme?

  • Windows 7 on my iMac won't play sounds through headphones

    On Windows 7, I can't make sounds play through my headphones plugged into the audio jack; the internal speakers always do it instead. The headphones don't appear in the "Playback devices" column, even though RealTek recognises that something's been plugged in/unplugged to it.
    Also, the latest version of Boot Camp software drivers I burned to a DVD after upgrading to Lion (v.4.0) refuses to start; it keeps saying that 'Boot Camp x64 is unsupported on this computer model"; I was able to install the v.3.0 drivers by using "Troubleshoot compatability" within the Drivers/Apple/BootCampx64 before, but now it insists I use setup.exe- which refuses to install, even in compatability mode!
    It's incredibly aggravating, since I always use my good headphones for gaming so I don't disturb my wife! Help!

    So the Bootcamp 4.0 drivers won't work with my 2008 iMac? I'm running 3.3 then, and the problem persists.
    I've just tried uninstalling the RealTek drivers; Windows seems to auto-install a "High Definition Audio Device" that DOES play sounds through the headphones... albeit incredibly quietly. Barely perceptible at full volume. I've tried to install the Cirrus drivers from the 4.0 Bootcamp disk; they claim to install correctly (in less than a second, which makes me skeptical), but they still don't appear.
    It seems I can have Realtek and no headphones, or no Realtek and minimal sound...
