    Mythbuntu 11.04 SPDIF Toslink Sound Drops Out

    I have found many instances of this issue with various past, versions of MythTV. I haven't yet found any post to version 11.04 of Mythbuntu yet.
    I have tried every version of sound card and configuration thereof with no prevail. The sound cuts out completely randomly for random amounts of time.
    I also tried turning off the additional audio processing/buffering in the TV Playback portion of the menu.
    Any thoughts?
    I'm using built in audio on an Asus motherboard which has the toslink built in.
    Also, let me know if there are any cmd outputs you will need.

    S/PDIF is a one way communication..
    It sounds like (no pun intended) your problem could be physical/mechanical.
    Toslink is optical..are you sure your cable is not broken, bend radius too small ?
    Both cause marginal signal conditions.

    I would use coaxial S/PDIF over optical whenever possible.
    Try a new Toslink cable, check it plugs in properly.

    I will give it a try and let you know.(The cable was from a buddy, so I don't know how it was treated.)

    I had a problem with dropouts too, using SPDIF Coax Cable on 10.4. Eventually I ran out of inputs on my amp and bought a box that receives Coax Cable and changes it to Fiber Optic Cable. That was the end of my problem. I wonder if myy problems may have been due to a little different voltage potential on the Amp than on the HTPC. Good luck!
