well im bummed

sdl audio just refuses to play nice with raw device

aplay 48k works fine though

[EDIT]

Tried to stop other things that might be interrupting...
killall -SIGSTOP pulseaudio
killall -SIGSTOP tonegend
killall -SIGSTOP that maemo-x-input-sounds
killall -SIGSTOP browserd
killall -SIGSTOP mediaplayer
(didn't seem to help, but hey fun times - resume with -SIGCONT)

Some interesting alsa things

cat /usr/share/policy/etc/current/alsaped.conf

cat /proc/asound/RX51/pcm0p/sub0/hw_params

-------- (while playing dosbox SDL at 48k)
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 48000 (48000/1)
period_size: 512
buffer_size: 1024

-------- (while playing mplayer output at 48k)
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 48000 (48000/1)
period_size: 500
buffer_size: 24000

hmmm! hmmmmm!

[edit]
what sdl calls 'buffer' size, alsa sees as 'period' size. setting sdl_buffer/alsa_period to 511 results in alsa buffer of 1022. setting to 513 results in 512/1024...

and this seems to be a subject of some activity (!)

if you just want mplayer output without pulseaudio, use
