Why can't i access /dev/dsp or /dev/snd on my XO

[Andres Cabrera]

How about just reenabling OSS emulation? It's included in alsa, so it
should be no problem, maybe it's just a case of modifying
modprobe.conf.
I second Victor's suggestion for the csound api, though. I wonder if
there is a major impact on performance by using it?

Cheers,
Andrés
