    I know this is a frequent issue, but I've never seen a post with a resolution. Perhaps someone can help direct me.

    Every HTPC build / home receiver combination I've used over the last 15 years always has the same issue that audio output doesn't kick in for about 1 second after the signal is sent to the receiver. It appears that this issue is specific to when the audio is passed to the receiver over HDMI only. For watching movies, this isn't much of an issue since once the audio switches in, it stays on, but it is an annoyance since the clicks when moving between icons and other small duration audio samples that are about 1s or less in duration never get output to the speakers at all.

    I spoke with Onkyo (my current receiver is RZ-810) and they say this is a common issue with connections to PCs and that the only resolution would be a software fix and there is no receiver setting to tweak.

    Does anyone have any info on how to set either Mediaportal, PC sound settings, or LAV tweak so that this doesn't happen?

    I Also got an Onkyo AVR and the only solution to fix this annoying silent stream bug is a third party software.
    I've got the best results with sound switch v2

    MEGA

    At this moment there is no other way to fix this.

    Thank you for your response, but I can't see how this addresses the problem. I tried installing sound switch per your link and it appears to just be a mixer over the top of the windows mixer which in no way effects the sound delay problem. Am I missing something?

    Thanks again.

    Ok let me try to explain the problem. Your sound delay is also known as the "silent stream bug".
    In easy words the Problem is that after every GUI Sound in MP (or other Programms) the Audio stream stop and the AVR lost the connection. To reconnect the AVR needs some time and this is too long for short sounds i.e. clicks.

    The above SoundSwitch v2 sends an silent sound stream to the AVR so that the connection stays active and you can hear all other sounds like they should.

    There are some other Apps like SPDIF keep alive, SPDIF k.a. and more that try to do the same, but for me only sondswitchv2 works well.

    Thank you for your description. I'm thinking I must have set something up wrong. I'll play with it again tonight.

    Thanks
