the noise might be caused by a noisy microphone amp (even if there's no microphone plugged). By mutting the microphoe, the noise may disappear.

How long is the lag? By default the buffer size is large which causes around 0.2 second of extra lag but makes audio stable (this is to allow audio to kinda work on busy or on MP systems). You could try to use smaller buffers, for instance add: sndiod_flags="-z 480" to /etc/rc.conf.local and restart sndiod with: /etc/rc.d/sndiod restart but I don't recommend this unless your system stays idle. > The last similar problem happens when I am playing a html5 video and I pause > or it stops to load, the audio gets desynchronized.
