pulseaudio -vvvv

If try to load module-equalizer-sink when isn't using ALSA directly (i.e without pass through any alsa plugin) the mudule crashes the PA server.

This also occur if try to load module with OSSv4 backend.

The only way to equalizer module load without crashes server is running with alsa and not do anything in alsa config files, so PA connect directly to hw plugin.

do dsp_logic of equalizer allow pulseaudio to rewind audio of any size ?
