/dev/dsp and /dev/audio are the OSS nodes. ALSA uses /dev/snd/* . You'll
find that /dev/dsp is provided by the snd-pcm-oss ALSA module. What you
need to check is: ``lsof /dev/dsp* /dev/snd/*''.

If an app grabs OSS's /dev/dsp or ALSA's hw:X, then dmix won't work as
they are exclusive access methods. ALSA apps should use "default".
