Using pulse audio I assume?

A few options to get this pulse issue: use native Alsa. Use ALSA:pulse
driver (which is pulse's alsa emulation).

If you do want to use native pulse driver for some reason, change the
sampling rate on the pulse audio server from the default 44.1kHz to 48kHz.
Pulse has issues when resampling audio
