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 pulse
server sampling rate from 44.1kHz default to 48kHz.

For some reasons, when pulse have to resample to 44.1kHz, it sometimes plays
a loud hiss.
