Qbittorrent 3.2.3 and audio lag

Post by neXus »

Hi.

I'm having weird audio lag when Qbittorrent is active. No matter if it is downloading or in idle, or even when I set upload speed to 5KBps, when watching movies or listening to music, or even videos on YT, i have ranodm audio stuttering. When Qbittorrent is disabled (shutted off), everything is back to normal. No audio stuttering.

Running Win 10.

I have the same problem with version 3.2.3 on Windows 7 (x64) so the issue is probably not Windows 10.

potplayer for media playback.
chrome x64 latest version for youtube playback.
as I mentioned in my own thread it happens even in games  (not cutscenes , when playing games) if qbittorrent is running in background.
I'll try to record the desktop to see if i catch it.
AMD Phenom 1055 T
6 out 8  GB of memory used at most (chrome tabs are hungry). Swap file is system managed and set by default at 1280MB.

qBT write cache size = auto
qBT cached used????  can't find it . are you refering to "Total Buffer size"? it's about 28MB

One more thing that I noticed, is that Qbit is slow in fetching trackers thus starting download needs a lot of time. And that is for files where there is a large number of seeders and peers.
