Audio skipping


Recommended Posts

I searched and did not find anything that helped, and the closest was the one a ways down titled "Strange audio error when uTorrent active..then PC slows down" but not really the same problem. If there is a topic about this that I missed please direct me.

My old PC ran windows XP and never had any trouble with utorrent. My new PC is running Vista (not by choice).

The problem is a bad audio skip and overall slow PC, utorrent was using 90-100% CPU. Nothing really new to me so I shut down Avast p2p which brought it down to 60-70%, I set affinity to just one with no effect. I went into utorrent and changed the global maximum number of connections to 200 which dropped CPU usage down to around 5%.

However, the problem is still there, I still get the audio skips and overall slow performance. If I shut down utorrent everythings fine, music, videos, progs etc. I have also tried all my players such as WMP, RealPlayer, Classic, VLC etc. same effect.

If you need any info such as HJT logs etc let me know.

Any help or direction would be great. Thanks.

But thats the thing, there is no extra CPU usage, if that was the case I could fix that on my own, as I did, since my last post utorrent slowly went down to a now average of 0.44. With over all CPU usage at just 5%. Its that there is nothing pointing to one thing or another.

That's not the full P DLL list. You need to click utorrent.exe and enable DLL mode (Ctrl-D) ;) You can edit the post above or post it below. As far as possible causes.. check to see if outpost has some "dns resolution" on peers it intercepts. Usual Avast services don't appear to be the problem, and you're not running much else. The DLL list should show something injected which shouldn't be. At least I hope so.

What did you change the Preferences FROM to make it 200. CPU overload due to active connections definitely suggests firewall or security software centric around internet packets (avast mail or web scanner)... :/

No problems with DNS or outpost for that matter. I uninstalled it just to make sure and had the same problem.

The active connections were set at 750 (same as on my old XP system). But yes some routers (running NAT or a firewall with SPI) can become slow or cause other problems when dealing with too many connections. However I have changed it back to 750 without any increase in CPU usage or other problems. I have also killed Avast with no effect.

I'm having exactly the same problem and I'm 100% sure it's utorrent related. When it's not running, everything seems to be fine, but once I run it, after couple of days those strange skips in audio/video are starting to occur. To fix it, I have to reboot my pc or wait some longer time after utorrent is closed.

I had that problem already with some older version of utorrent. I then thought it might had something to do with Vista, but now I'm using Windows 7 and the newest version of utorrent and those skips are still here.

I hope you guys can fix it. It's really, really annoying. :(
