Bug Report Audio Stutter #streamfail

[jayee]

I've been having this issue for the longest time and can't seem to figure out a way to solve it. When I stream with OBS on Twitch, the audio on the stream 'blips' every so often. The best way I can explain it is like an audio 'hiccup' effect. The video is perfectly fine, no issues there. There aren't any audio/video sync issues either.

I've checked this problem on 3 different computers and all of them have the hiccup issue. My stream is on 24/7 so if you guys want, you can go check out exactly what I mean. http://www.twitch.tv/jayeeyee

I hear it, though I need more information. First of all I can tell you that this does not normally happen, and it would be particularly strange if it happened on three computers unless they were all the same type of computers. I would start to suspect perhaps some sort of common configuration between them.

I would like log files for each computer and want to know if it happens only with a specific game or program active. I am most interested in finding out what that would be caused by, because that seriously does not normally happen. There has to be some link, something similar between the three computers, whether it be software (a game they're running, other software they could be running), or hardware. What you tested on each of the computers.

I didn't test it on three computers. I meant I watched the stream on 3 different computers. #lulz

Sorry for the mis-communication.

It's no problem. You had me worried.

Anyway, so back to the drawing board. As I said this doesn't normally happen, though it has happened with other users in the past so I'm pretty sure we can probably find out what the problem is. Certain sound devices can have this happen.

For example I had this one guy who had both an integrated and dedicated sound card (two audio devices on his computer). and he would have almost the same thing happen, but only with his dedicated sound card (though note that most dedicated sound cards are also usually fine).

I have also had users with similar things happening who had their computer improperly overclocked. Windows itself doesn't calculate time the same under some overclocks and then it causes audio to jump and create these little skips.

I think if I recall it's also happened when a user had a particular device plugged in to his system. Somehow it caused it to happen, I have no idea why though.

I suspect it's something going on at the device level, though I'm not entirely sure. Just throwing my prior experience out there. Even at the hardware level, computers tend to be prone to imperfections or bugs, though I just can't say for sure what the case is all the time. I do hear it, though it's difficult for me to diagnose other than throw out what I've experienced before.

THANK YOU SO MUCH JIM!

Your list of probabilities helped me narrow down my issue to one specific cause and that was indeed the CPU. I had my O/C utility start on load-up with an O/C'ed profile. I never paid much attention to it until your comment aboutoverclocking & windows calculated time totally made a lightbulb pop inside my head. I had my clock speed reset and now the problem is completely gone.

Once again, thank you very much for your support and time. I greatly appreciate it!
