I never had any trouble at all with the OSS compatibility modules.
Not sure where this statement comes from, if it is an old source, maybe
they meant the old, true OSS modules (which have been removed from the
linux kernel quite some time ago, though), where this was certainly true.
The snd-pcm-oss and snd-mixer-oss modules however are *not* OSS modules,
but come from ALSA and just add an OSS-compatibility layer to the ALSA
sound drivers, so that applications that rely on the presence of the OSS
devices like /dev/dsp remain usable.

If you don't want snd-pcm-oss you should blacklist snd-pcm-oss.
When you blacklist soundcore it is not much of a surprise if you get no
sound at all ;)
