Is this with foobar2000? Most audio players won't do this, as Windows will mix together the sound from all applications and output it at in a fixed audio format. What version of Windows are you using? Things were a bit different with Windows XP.
Another possible solution that'll work with any stereo source is to use analogue audio. There's no format changes this way so you won't get any interruptions.
I can reproduce this problem by deliberately changing the output format Windows uses in the middle of a song, but otherwise I don't encounter it because my devices don't switch format all that often.
The thing is even if I send decoded PCM audio, I still get the audio cut off. Anytime the receiver display changes from "decoder off" to anything else, I lose that first second of audio. Doesn't matter what kind of audio I send it, or from where. This may not happen with optical or analog cables, I don't know, but really I want to use HDMI for all my connections.
I was using foobar2000 with my windows7 machine. The audio plays instantly over my tv speakers, through HDMI, and connected to my receiver, as long as the receiver is off and I select my Samsung tv under sound>playback devices. If I turn on my receiver and have Windows re-detect the connected devices, and then select my tv again under sound>playback devices, then the sound gets cut off at the beginning over the receiver's speakers. I've never heard the receiver immediately play any audio, ever, since I've owned it, without that first second of dropped audio. If this is normal with HDMI and Yamaha, why couldn't they have been honest and tell me that when I called them twice about it? Instead they're telling me that should never happen, and I should get it serviced. I really have no desire to disconnect everything I own for electronics, drive almost 50 miles to my nearest repair facility, drop it off, go 2 weeks without my receiver, and have to drive back again to get it, just for them to tell me there's nothing wrong with it.
I get the gut feeling that these Yamaha receivers aren't quick enough to pick up audio over HDMI - they take a second to receive the signal, identify it, and switch over. I used to think maybe there's some "mode" or setting I need to disable or enable to bypass this automatic switching mode, but I've been all through the settings a dozen times and I can't find anything that has helped.
What I did find is that the only way to avoid that first second of missing audio is to use a device that keeps a PCM connection open inbetween tracks. This doesn't work well for movies and video files unfortunately, since, for instance, when you insert a DVD or blu-ray, the menu may have no audio encoding or at, or it may have stero, or surround, but then when you start the film, you get warning and disclaimers which have no audio, so then the receiver says "decoder off" inbetween, then when it starts the movie itself the audio switches again to the correct audio stream, again causing the first second of audio to get ignored by the receiver.
But this does work for audio tracks - if your player keeps a PCM audio connection and doesn't drop it between tracks. For instance, with my Panasonic player, If I plug in a USB flash drive, with flac or mp3 tracks, when I first load the tracks on screen, the receiver says "decoder off". So when I first start the first track I want, I miss the first second. But when I stop playback, the Panasonic blu-ray player leaves the PCM connection open to the receiver - because evn though no files are playing, the receiver still says "PCM". So now when I start another track, I hear it instantly, no lost audio. On the other hand, My Micca EP950 media player cuts the audio connection inbetween tracks, even if it's just smoothly switching from one track to the next track in the folder. This means that as the player switches from one track to the next, it very briefly drops the connection and restarts it for the next track, causing the receiver to display "decoder off", then back to "PCM" again, causing me to lose 1 second of audio off each track as it switches.
So really this just seems like how this Yamaha receiver is. It's sad that Yamaha can't just admit to this when I ask. Most devices I know seem to drop the audio connection when there is no playback - my blu-ray player is the only device that seems to keep the connection open between audio tracks.Edited by eagle_2 - 11/5/12 at 9:46pm
