Question / Help Stuttering Audio, help?

PhoDeNguyen · Aug 17, 2013

I streamed for the first time yesterday, and the audio coming from my game and skype are perfect. But the audio from my webcam stutters immensely. Here' s a recording of the stream http://www.twitch.tv/phodenguyen/b/446950535
Any help? PLease?

I've heard this before, last time it happened the user had an overclock with the wrong settings which was causing his audio packet timing to do almost exactly what's seen here. If you're overclocking, you may want to double-check your settings to make sure it's a proper overclock, or try without overclocking and see if that fixes the problem.

Otherwise, if possible always post a log file, instructions are in the global stickies at the top of each forum

Here's my log file.
What does overclocking mean?

Well if you don't know what an overclock is then it's probably not that. Overclocking means making your CPU run faster with custom settings and equipment.

I'm unfortunately not entirely sure of why this is happening for you as there's realistically no reason why this would happen for someone without an overclock.. I've never seen this really happen before. Are you sure you're not increasing your CPU speed or anything?

PhoDeNguyen · Aug 18, 2013

I'm fairly certain; I just got this computer this year, and I haven't modified it or anything.
Do you think it could be due to the fact that I'm broadcasting from my webcam while also using it as a microphone?

Lain · Aug 18, 2013

No, that typically shouldn't be an issue.. Actually you're right, that stuttering was only with your mic. I thought that was your desktop sound, fortunately it's not. Not sure what's going on exactly.. Do you think you could check your windows sound control panel mic settings? Try increasing the hz of the mic, it seems to be really low. I'm wondering if that will make any difference at all.

Control Panel -> Sound -> Recording devices -> right click on your default mic -> goto properties -> Details/Advanced -> change your hz here to something higher if it's possible

PhoDeNguyen · Aug 18, 2013

Thank you for all your help so far by the way, I appreciate it.
Unfortunately It's already set at the highest HZ setting (16,000)

Lain · Aug 19, 2013

Hm, I'm totally baffled by this. Lifecam VX-3000? Hm, I did a search on the forums and it appears that the VX-5000 had some strange issue with its audio as well, so maybe this isn't some localized incident. I'm not entirely sure why this is occurring.

Okay, new idea. First, disable microphone in settings->audio. Then, right click the device source for your webcam, go to properties, set the mic to be used there instead, then turn on "use buffering" (at 0). It will cause your mic data to come through in a different way which may make it work for you in this case

Question / Help Stuttering Audio, help?
