OSS audio results in noise (when playing bass-heavy music)

[coypu%SDF.ORG@localhost]

I've built all my packages unprivileged and was having some trouble
running dbus for pulseaudio, so I switched to oss.

Playing audio from Firefox, it's adding some noise whenever playing bass
sounds. It may have to do with me using low-end headphones that are
simply not up for it.

How do I manage this?

Thanks.
