Hello. Friend of mine recently updated his OBS and now has the following problem as seen here - http://www.twitch.tv/houseofsim/b/471162021 - His microphone seems to broadcast fine however his desktop audio and his webcam seem to be trying to play at X2 speed. He says he has not changed his settings from his old obs settings to now.

We have tried uninstalling and ripping out OBS settings in appdata and doing a reinstall with no luck. Here is his log file.

Help would be appreciated. He does not want to keep using XSplit (which works fine at similar settings) to stream. Thank you for your time!

CPU Speed: 7053MHz

Okay, I sense an improper overclock here, which is causing all the timing information sent to twitch to be off, which causes it to appear "sped up" when played back as a vod. I am very familiar with this and have seen this before and this is almost always what the case is. If he's using anything to overclock he needs to go back and configure it properly, or worst case, disable it completely, because it's completely messing up his entire system's operating speed.

I'm not sure any of these are your problem but...

"width: 1364, height: 768" ... Don't stream at this resolution at 1000 bitrate. Either increase the bitrate or downscale. To keep it simple for now I'd downscale to something close to 480p. Once stuttering problem is solved you can trying increasing it again.

"00:44:51: Interface: Wireless N-300 USB Adapter WNA3100 (802.11, 52 mbps)" ... Don't use a wireless connection for streaming. Use wired.

"samples per sec is 48000" ... try setting all your devices and OBS to the same speed. You have some at 44100 and some at 48000. I'd just set them all to 44100.

"NVIDIA GeForce GTS 450" ... Does anyone know if this video card is fast enough? It compares closely to my old GTX260 which is too slow to run OBS.

"00:44:43: CPU Speed: 7053MHz" As Jim said, this is very strange.

He hasn't had trouble with any of the previous settings. His wireless, gpu etc...wouldnt have any effect OBS registering his processor speed at what it couldn't possibly be set at short of cooling his computer with liquid nitrogen.

Any word on what could be causing that?

All I can tell you is this: when you record and everything is sped up, it means that the timer on the PC is moving too fast. It's almost always due to improper overclock, though I could be wrong -- either way, regardless, it's always some sort of PC/bios/etc setting somewhere causing the the PC's internal timer to move "too fast". Also when the log reports that sort of incorrect speed at the top I mean I just can't help but to feel something is set up incorrectly.

I just have seen this sort of thing a number of times before and there's just nothing else that could possibly cause it outside of the PC's internal timer. OBS needs that timer to be properly on time otherwise it cannot function properly.
