[SDL] prboom and doomsdays sound delay problems?

[Jonathan Atkins]

Just run: ps -auxww|egrep 'artsd|esd'
and to check the device permissions: ls -la /dev/dsp
then: id
see if any groups from the id command match the dsp and the the dsp has group writability.
also export ESD_NO_SPAWN=1
to prevent SDL from starting esd
you may also wish to use an alternate dsp if you have two sound cards...: export SDL_PATH_DSP=/dev/dsp
of course, you'd need to specify the proper dsp device.
