Question / Help Help OBS audio cuts out during stream

Its not on the playback or the recording for my stream PC I mean. The only place it shows up anywhere is on my gaming PC under playback.

Another thing I wanted to note is that even when I'm in the OBS preview, my FPS won't hit 30 with the capture card displayed. It idles at about 28 fps.. Something is definitely wrong and lagging my frames even when I'm not streaming.

Streaming PC specs:
Intel Core i7 K875 @ 2.93GHz
8GB 1600Mhz ram
Dual 10k Raptors raid0
Single Geforce 7950gx2 (dual GPU single card configured in SLI and non-SLI)

Its hard to test if the problem is in fact gone or not, however, I just had a 2hr40min stream session with no audio issues. My stream still has 21.23% lagged frames though. What is a normal amount of lagged frames and any ideas on how to diagnose/fix it? You have been very helpful thus far!

I think it might just be your CPU struggling to encode 1080p30fps but I can't be sure. That CPU is a step down from the i7 920 isn't it?

hm I'm not entirely sure.. Though its been a long time since i've looked at that generation of core processors. IIRC, it was more expensive than the 920 but could be for the "K?" I haven't bothered with OCing it since I figured it shouldn't have a problem at 1080p/30fps as a dedicated machine. it doesn't run anything but OBS. Max CPU usage is well below 40% throughout the entire stream.

Yeah, after a bit of research it is a step down. You may be limited by CPU here, but I do sort of doubt it. Maybe think about a mild overclock if you really want to push things, though I don't recommend trying it just for OBS if you've never overclocked before.

It is possible, but I really don't think an OC is the problem.. I may give it a whirl to see if a moderate OC to around 4.0Ghz does the trick.

My gaming PC is:
Processor: Intel Core i7 980x 4.4Ghz Overclock
Graphics Card: nVidia GTX 670 2Gb x2 SLI
RAM: Corsair Vengeance 16Gb 1600
SSD: 128Gb Crucial M4
HDD: Western Digital 1Tb HDD (Media Storage)

I was wondering if the 7950gx2 is having problems rendering frames in the frameviewer and producing lagged frames in my stream but that seems a little bit hard to believe too.. I may have an extra old 8800gts lying around somewhere..

Turns out I don't have the other graphics card to test with. My audio problems seem to be resolved. Should I make a new thread to diagnose what the lagged frames are or do you have any suggestions other than a new gfx card hilalpro?

I put in one of my gtx 670's in the streaming PC and it streams with <1% lagged frames. Looks like my graphics card isn't good enough for the streaming PC. A bit hard to believe, but I guess that's how it is. The PC handles games with no issues but cant render the frames on OBS :(

What is the lowest spec gfx card for 1080p/30fps and 720p/60fps streaming? Don't want to keep a gtx670 in the stream PC if there are relatively cheap alternatives that are guaranteed to do the job

you could grab an hd 6670 for like 60 buck's and it should be fine for just that.

I just realized how old this thread is, but I recently just went through this same problem, only to realize that my noise gate was set to high. So, my audio wasn't randomly cutting out because of my system, but because I told it to do so unless I got reaaaalllyy load :X
