How can S/PDIF just stop working? [Solved! this time for good!]

I have S/PDIF cable as my main output from my computer to my receiver, and it worked fine, up until now.
Earlier today it still worked but I turned my computer off and after a while on again, and then it just didn't work.
I tried to troubleshoot the problem, and noticed that my sound starts working if I mute the S/PDIF (I do have another cable coaxial?) my sound comes back.
After not much luck trying to find a solution. I did check the Wiki page on ALSA and read the part on how to get S/PDIF working...
It didn't work.
Anyway I lost patience and removed alsa-utils and it worked for a while and now it doesn't work again.
I though I'll just ask why would this happen but given it again doesn't work the real question is why is this (keep) happening?

To keep anyone that's interested up-to-date...
Doing the same as previoulsy; meaning that I would just reinstall alsa-utils, use alsa-ctl store and it would magically work; didn't work.
Now I'm starting to doubt that it worked first time round, but it did. Becuase I did tests to see if it really works.
I was muting S/PDIF on and off and quality of sound changed instead of stop working.
I don't know why it worked previously, I doubt it was the reinstalling of alsa-utils.
I have no idea what it actually was the reason.
I'll do more research.

  • [solved, this time for good] openvpn dns issue

    i guys! i'm having some trouble connecting to the university vpn.
    i installed and configured openpvn as said here in the wiki https://wiki.archlinux.org/index.php/OpenVPN
    i installed openresolv too and it seems to work.
    the configuration file provided by the school is ok and it works well with windows openvpn-gui.
    the problem lies in the script for openresolv given in the wiki. it doesn't work for me... these are the output of openvpn at the point it loads it:
    Wed Feb 9 23:28:37 2011 SENT CONTROL [openvpn.unive.it]: 'PUSH_REQUEST' (status=1)

    you can find the openresolve script at the bottom of the openvpn article in the wiki.
    should i edit it someway?? what about that "foreign_option"? i don't get it
    if i try to connect to the vpn avoiding the script it works, i can connect to the ssh servers of the school, but i can't browse the internet, as the dns aren't set properly.

    well, i had the occasion to test this thoroughly, connecting to the school wifi, and still it doesn't work.  the internet browser just shows the not-so-welcome page of the school intranet. openvpn reports no errors or anything. ssh works. it worked connecting from home..
    i connect to the network via wifi, using wicd and a dhcp setup. the dns in resolv.conf are changed accordingly when i connect. they are NOT changed again when i connect to the vpn. is that right?
    i cant figure why it worked from home (and i'm sure i was in the vpn)..
    any hints?
    EDIT: it works disabling the openresolv script. the dns in resolv.conf are always the same!! damn this is nonsense!

  • After getting an update from 10.6.8 many of my programs were no longer able to open. How can I undo the update or solve this problem another way?

    After getting an update from 10.6.8 many of my programs were no longer able to open. How can I undo the update or solve this problem another way?

    Do you have a bootable clone from prior to the update? If so, roll back with that.
    Are your apps that won't open PPC and do they need Rosetta? Do you need to activate Rosetta?
    Have you considered reinstalling 10.6 from your install disc and then coming forward with the 10.6.8 Combo Updater, then doing software update and not including whatever it was you installed that caused this propblem?
    By the way - what update was it that caused this problem?

  • Apple's Mail 4.5 just stopped working. Any Fix for it, please?

    Apple Mail 4.5 just stopped working - no email gets in or out.
    Details:
    Account is set to get me connected to my gmail address.
    When try to send email  the wheel for sending spins endlessly with no result.
    No incoming emails arrive either.
    When I open the same email address directly from Gmail in Web browser  all works OK.
    Settings of Mail are exactly as recomended.
    Did trash the account and tried to re-create again.  The Mail gives message that Gmail server is not responding.
    Did try to create  another account with completely different server - the same result  -message that this server is not responding either.This is incorrect  because I can open and use Gmail and the other email perfectly well with Firefox browser.
    Obviously the problem is with Apple's Mail not able to make connection and operate properly.
    I dont have any special firewall setting, etc. All is set properly. A couple if days back  Email 4.5 worked ok.
    The question is: How to fix  this Email 4.5 and make it work again (or I should just get rid of it altogether)?
    Thanks for any competent tips, fellow Mac users!

    Hello
    just to esaly confim a plist , file or other problem corruption into your curent account
    create just for test a new account ( system pref -> accout panel -> click PLUS button bottom left of window ) , then perform mail setting for your gmail accout let see if that work ?

  • How can I publish just one page at a time?

    I switched to a new computer, so I moved the domain file. When I open iWeb, all the pages are there. I made one small change, and only want to update the one page, but since it's on a new computer, all the pages are red and I can't publish just one page - every time I try, iWeb tries to publish all the pages, and it errors out every time. Can anyone tell me how to make it publish just one page at time in spite of the fact that all the pages in the sidebar are red? The only reason I can think for the error message is that there's too much content to do it all at once.

    Yes. If you are uploading to a server and not MobileMe, then just select the option publish to a local folder.
    When you have done this, then use Cyberduck or Transmit and upload just the one page from your site folder to your server, plus it's resultant file. So if you just want to upload a Welcome page for example, use Cyberduck to upload just the Welcome.html page and the Welcome files to your server and into your root folder on your server, which would be either a public_html folder, a www or htdocs folder.

  • How can I view just one spread at a time of my interactive PDF?

    Hi,
    Apologies of this has been asked before.
    I am creating an interactive PDF of a magazine, to be viewed online.
    I would like to be able to 'flip' through the spreads one spread at a time. I do not want to be able to scroll down.
    I do not want to use SWF for various reasons (viewing on ipad etc)
    When I open the magazine online it displays like this (one spread below the other) Is there a way for the spreads to be 'stacked' so I can only see one at any one time?
    Thanks
    Ben

    Hi Ben,
    You might want to create a pdf portfolio and check.

  • How can I make sure the engineer comes this time?

    Hi there I noticed at the beginning of last week that my broadband had slowed to a crawl. I checked the phone and could not get a dial tone. Ringing our number made the phone ring but no conversation was possible. Broadband was synced at 640 Kbps I got the automated line checker which found a fault near my property - the telegraph pole in the graphic. I fault was logged on May 1st and I got a repair date for next Wednesday 9th which I wouldn't be able to make so I went to rearrange and was able to pick last Saturday morning 5th May. About 2 hours after i rearranged it I had a call from Mumbai, he said someone was going to be coming on the original date of Wednesday, I assumed that as I had just rearranged this would not now be happening, but couldnt get him to understand that the new dte of saturday 5th wasshoes ing on my fault update page. Sure enough nobody came on the Saturday . I have now rearranged it for the afternoon of Friday 11th May My question is how do I find out if an engineer is still going to come on Wednesday afternoon (I can try to take the afternoon off from work) or has that now been properly rearranged for Friday, given that last time it was irrelevant that Saturday was showing on my fault update page for the engineers visit? Is there any way I can confirm this is logged properly on the BT systems? Sorry about the long paragraphs posting from an iPad doesn't result in correct formatting!

    Haha, the engineer turned up today, on the wednesday, which was the original date allocated! 
    Despite me rearranging for last saturday morning, (showing up on my "track my fault") then, following a non show, rearranging for next friday afternoon, (showing up on my "track my fault") the OR enginner phones me (on my mobile obviously) to tell me he is her at 12.20 on the wednesday.
    Luckily I was at work and could get home in 20 mins, and the chap (really nice) said he would make a start. By the time I got home he told me he had fixed it - the connection was ?corroded (6 yr old house) on the BT side of the fence.
    There is a total disconnect between the "track my fault" page with BT and Openreach
    If my mobile had not been in signal range and I had not been able to get home to meet this really nice OR enginner, and had they not turned up on Friday with an afternoon lost from work I would not have been happy!
    I have an installation date for BT Infinity in 2w time, on price alone, but hope i don't live to regret this
    I would appreciate a reply as to why "rearrange my appointment" has no effect

  • How can I get Messages to show the correct time for read receipts?

    Messages in Mountain Lion shows the wrong time for read receipts. For example, my iPad will show a message was read at 3:37 pm but if I open Messages on my MacBook, the read receipt shows the time that I opened the Messages app as opposed to the time the message was actually read. This is not too much of an issue if my iPad is handy, but really, shouldn't Messages on my MacBook be able to show the correct time the message was read? It syncs all the other infromation with Messages on iOs.
    I should mention that if Messages is running on my MacBook when the recipient reads the message, then it does show the correct time the message was read. It's if Messages was not running and I re-launch it that the read receipt time gets mixed up.

    HI,
    As far as I am aware Messages marks or time stamps an iMessage at the time of receipt rather then the time you got around to reading it.
    I will admit that in most cases reading and receiving as the app opens will be near enough the same time in some conversations.
    Adding Time Stamps to Chat is what iChat has always done particularly with AIM based Chats.
    The "Sync" in Messages is "display on all devices"  and after that each iMessages is dealth with separately on each device.
    There is no syncing of deleting/dimssing an iMessages or having read it on another device.

  • One day, my bookmarks tabs just stopped working. I only have 12 pages bookmarked, why is not working anymore? I can't click the star, or manually do it.

    It used to work, but now when I go to click the star, it turns yellow for about half a second, but won't click and bookmark it. I cannot bookmark it manually under the tab either, it simply does not click--no option comes up, and nothing is saved. I didn't turn anything off, it just stopped working, randomly.

    This can be a problem with the file places.sqlite that stores the bookmarks and the history.

  • My ipod touch 5th generation keeps wifi signal for 10-30 minutes and then just stops working.

         I've had my ipod for about a month now and it worked fine up until this week.
    This week I noticed probelms with the wifi. I would be just on facebook or browsing the web and the wifi would just stop working. Every time I turned wifi off and the on again it would give me about 5-10 more minutes of wifi before I had to do it again. I've never expeiranced this with my other 4th generation or 3rd generation ipod touches. The wifi itself is not the probelm because it works just fine on my laptop. Today I updated my software and the probelm was not resolved.
         I need help sould I got to the Apple store and have them check it out?

    Does the iPod have the problem with other networks?
    Do other devices work OK?
    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router
    - Reset network settings: Settings>General>Reset>Reset Network Settings
    - iOS: Troubleshooting Wi-Fi networks and connections

    - DOes the router have the latest firmware?
    - Restore from backup. See:

  • How can i extract just documents from time machine backup?

    How can I extract just my documents from a time machine backup?   I had to re-install Lion after the update screwed things up, the Genius Bar guy told me to re-install each App, and then transfer just my data (documents) back but didn't tell me how.   I only see how you can restore the entire snapshot of what was on my MacBook that day, I don't see how to select specifics. 

    Hi,
    Install a fresh Lion OS on your Mac. After this is done, then connect your time capsule. Click on the time machine icon in the dock bar so you will enter in time machine. Select the document folder and any document or all you need. The same thing you can do with iPhoto, Emails, etc.
    Let me know

  • Streaming radio just stopped working Firefox version 8, but I can get everything else. Add on's are up to date. I can't recall if it happened after the Firefox up date or after listening to last.fm or what! How to fix this?

    Streaming radio just stopped working Firefox version 8, but I can get everything else not on stream to work. Add on's are up to date. I can't recall if it happened after the Firefox up date or after listening to last.fm or what prompted it. How to fix this?

    I installed-enabled MS win media player firefox 1.0.0.8, i still did not get streaming, error box comes up and says 'stream load error', the 'windows media test' thing did not work, i tried iheart radio-no luck, so i disabled win media player plug-in dynamic link library 3.0.2629 and tested and still did not work, i also have plug ins: silverlight 5.0.61118.0 and quicktime 7.6.9 7.6.9.0 enabled. I don't know why all of the sudden i have a stream problem with firefox, yesterday, i tried on IE which i never use and had no problem with it. i will try to do more trouble shooting and see, its really frustrating, if can't figure out, i guess will have to revert back to IE which i really don't want to do, but---oh well. thx for help.

  • My iPhone 5s sounds stop working.i did not do anything it just stop working when I tried to turn on my music player all the sounds is not working I already check the volume and it is not also muted :( what happened can anyone solve my prob

    Hello everyone my iPhone 5s sounds stop working.i did not do anything it just stop working when I tried to turn on my music player all the sounds is not working I already check the volume and it is not also muted :( what happened can anyone solve my problem please

    Hey Kirby17,
    Thanks for using Apple Support Communities.
    If you are not getting any sound from the speaker, follow this article.
    iPhone: No sound or distorted sound from speaker
    http://support.apple.com/kb/ts5180
    Ensure that there is nothing plugged in to the headset jack or the dock connector.
    If the iPhone is in a protective case, make sure that the speaker port isn't blocked by the case.
    Make sure that the speaker and dock port aren't clogged with debris. If necessary, clean it with a clean, small, dry, soft-bristled brush. Carefully and gently brush away any debris.
    If an audio issue occurs when using a specific application, try testing other applications to see if the issue persists.
    If the iPhone is paired with a Bluetooth headset or car kit:
    Try turning off Bluetooth.
    If you experience difficulties with the Bluetooth feature, follow these troubleshooting steps.
    Restart the iPhone.
    If restarting doesn't fix the issue, ensure that your iPhone is updated to the latest version of iOS.
    If the issue is not resolved, please contact Apple Support.
    Have a nice day,
    Mario
