Spdif working but only for AC3/DTS, problem occured suddenly

Hi all,
My spdif output decided to stop outputting normal sounds. It will only work with AC3/DTS. This seemed to happen suddenly, one minute it was working and the next it wasn't. I hadn't changed anything with regards to the sound setup. IEC958 is unmuted in the Alsamixer app. Not sure what else to check. I think the problem occured when one of my apps crashed so maybe that has something to do with it but I tried rebooting, shutting down completely etc. I can't think of anything else to check.
Any help would be greatly appreciated, this is a media computer and SPDIF is my only option for sound.
Thanks,
Kevin

I forgot the power of ssh... The mplayer switches you suggested still result in 2ch. Here is the output of the alternative solution from the link you gave.
$ amixer set 'IEC958' 100 unmute
Simple mixer control 'IEC958',0
Capabilities: pswitch pswitch-joined cswitch cswitch-joined
Playback channels: Mono
Capture channels: Mono
Mono: Playback [on] Capture [off]
FYI: Every time I play something, IEC958 is muted again when I go into alsamixer.

  • My microphone is not working but only for calls

    I had my Iphone working perfectly until I updated to 4.3.1 after that I lost the microphone but only for calls when I use Skype, Video recording and may other features that uses microphone all of them worked. I did restore again to 4.3.1 and make a new fresh installation without recovering my data so now I'm not only without phone features but also need to load all of my data again. This occurs most of the time but about 2 of 10 calls the people can hear me so I think this must be related to baseband update or hadware issue.

    Might try setting the option in System Preferences > Sound > Input tab > check "use ambient noise reduction"

  • My online number is working, but only for 10 secon...

    Hi,
    I purchased an online number today, its all setup and working, but I can't hold the call for longer than 10 seconds.
    It does not seem to be my connection, as a normal skype VIDEO call works perfectly.
    Im on a BT infinity fiber line at 40MB.
    It seems to timeout from the callers end.
    Please can I get some advise or have a technical engineer help resolve the issue?
    cheers,

  • Kerberos delegation works, but only for 10 hours

    Hi all - and please forgive in advance if this isn't the right forum for the question.
    I have an application service which watches for a file to be dropped and then calls a SQL stored procedure which does a bulk insert into the DB from the file using unconstrained delegation to impersonate the service account of the application.
    It worked fine in testing, and it worked fine when we tested during the prod deployment... but the next day, it failed!  The error is the ever-so-helpful:
    Cannot bulk load because the file "<FILEPATH>" could not be opened. Operating system error code 5 Access is denied. .Procedure , Line 1
    Even more odd, when we restarted the service and tried again, it succeeded.
    Through trial-and-error, we found that if we restart the application service *less than* 10 hours before the file is dropped, it succeeds.  More than 10 hours, it fails.
    So... I'm guessing Kerberos ticket expiration has something to do with this... but that's where I lose the thread.  Is there some way to avoid this error other than restarting the service every night?  I assume some kind of modification to the
    application which "exercises" the delegation rights on a regular basis?  Any solution which doesn't require a new app build?
    Thanks for any input.

    You're on the right track as the default Kerberos ticket life time in
    Windows is 10 hours.
    I think that your only two choices are to restart the service or modify
    your code and recompile. For the latter option, you're going to have to
    post in an appropriate development forum (check the MSDN forums rather than
    the TechNet) as this forum is not for development support.

  • TS2972 i have done all 7 steps recommended by the troubleshooting articles and only when i restart my router does my library show on apple tv2 but only for about 5 minutes, this was never a problem before the updates of itunes and apple tv2,

    i have done all 7 steps recommended by the troubleshooting articles and only when i restart my router does my library show on apple tv2 but only for about 5 minutes, this was never a problem before the updates of itunes and apple tv2, i have spent insane amounts of money on the apple store buying movies and tv shows that i cannot watch anymore, and no there is no firewall on my laptop nor my router, so no port configuration is needed
    i have read many articles for this problem but there is no solution, some say restart the router, others say uncheck the option to sync iphone over wi-fi, others suggest not hitting the "done" button after setting up homeshare on itunes, NONE of them work. My itunes library disappears from ym apple tv 2 after 5 minutes or so

    Did not work. I've selected iMessage to ON and left it. After a few hours I recieved a message "activation unsuccessful. Turn on iMessage to try again". This has been going on for the past 3 days.

    My Acrobat 8 Pro is failing to print to a pdf from multiple software.  I get an error message that a repair fixes but only for a little while.  Pretty soon the trial version of 9 that I installed pops up telling me it has expired but it would take me to a way to buy a valid serial number and then 8 stops working again.  I’d be happy if the 8 I paid for worked right or I could get 9 for a small cost but I cannot afford $450 or $20/month.  I need a permanent solution that I should be already paid for with 8 pro.

    After multiple repair procedures with reboot in AA8 I was eventually able to restore the printing to pdf function from various software.  However I have again lost my Acrobat tab in Outlook 2007.  I need that back, but today an even bigger problem arose.  AA8 has stopped printing to fax.  It faxes a blank page.  The only fax printing option is “Microsoft Shared Fax Driver”.  My fax software is “Windows Fax and Scan” and it was working fine just a couple weeks ago.  My OS is Windows 7 Professional.
    I have tried doing the updates you referred to but I get error messages like these:

  • [solved[X superlaggy after hd went out of space, but only for one user

    So the netbook (eeepc 1101ha) went out of diskspace while running and froze. I freed up some space and restarted X, but it failed so I rebooted. Same story then. It either loads and becomes super slow or doesn't load at all. I use dwm wm which to my knowledge doesn't save to config files that might have been corrupted during the moment with no diskspace. Other wms have same problems too, but only for that user.

    If that doesn't work you may try moving all the hidden stuff to a backup folder and start the X session again.
    Something must be causing that and most probably it's some dot file stashed away inside one of those dot directories (you say new users work just fine so it's not a system problem).
    Apart from this I'm out of ideas, once I had XFCE (I know its not the same) act really strange and the problem was related with some corrupted saved session file, once I deleted it everything was fine again.

    Adding to Alan's answer:
    One of the problems that comes with these tricks for variable-rate acquisition is being able to match up sample data with the time that it was sampled. 
    If you weren't using either of E-series board's counters, there is a nifty solution to this!  You'll be using 1 of the counters to generate the variable-rate sampling clock.  You can then use the 2nd counter to perform a buffered period measurement on the output of the 1st counter.  This gives you a hw-timed measurement of every sampling interval.  You would need to keep track of a cumulative sum of these periods to generate a hw-accurate timestamp value for each sample.
    Note:  the very first buffered period measurement is the time from starting the 2nd counter until the first active edge from the 1st.  For your app, you should ignore it.
