Title: Audible Blip or Pop When Starting Playback On One System
Post by: glynor on October 25, 2010, 01:12:57 pm

I know I've seen threads about this before, but I've searched and I can't find anything.  On one of my machines I'm now getting an audible "pop" or "blip" that happens right when I start playback of most video and audio files.  It doesn't seem to happen in-between sequential files played, but only when starting from a "stopped" state.

This ONLY happens on my machine that is using analog 5.1 outputs off of the soundcard in concert with MC's DSP.  I have the Room Correction and Output Format DSPs enabled (Output format is set to output 5.1 audio using JRSS, but nothing else is really enabled).

The blip is very small, and you have to be listening at a moderate volume level to even hear it, but it is certainly there and audible.

Any hints?  Links to other threads?  Any love whatsoever?

I had a pop like that recently.  It turned out that the problem was with the Sony receiver connected with optical cable.  It had trouble with 96Khz (or maybe 192Khz?) files.  Anything below worked.  It was a little pop every 10 or 15 seconds.

There are also some other similar problems in this thread:

Thanks, Jim.  The audio system in this case is analog-only (with discreet 5.1 inputs on the back), and is the same one I've been using down in the man-cave in the basement for god-knows-how-long.  The computer hardware itself also has not changed.  So, something is different on the software side.  I suspect the DSP because I've only recently enabled all of those options (I got out my measuring tape and actually set up the room correction down there), but I'm honestly not sure.

It could also be the crappy Realtek drivers I suppose.  However, I DO NOT get similar pops when playing the same files back via MPC-HC.

I'll check the threads.  But anyone else?

Tried the play silence option in playback settings?

I agree.

Try Options > Audio > Play silence at startup for hardware synchronization

It is only used for audio playback, not video (since video requires audio + image sync).

I'll try that.  I am getting the blip with video files too.

By the way... This "worked".  Enabling that setting fixed the issue for audio playback.  It is still there for video files though.
