Hi Matti,

do you already read this?
But ALSA support didn't work with the internal soundcard, only via a usb 
headset, which uses the snd-usb-audio module. Because there doesn't 
exists an ALSA device for the internal dsp, you have only a Dummy ALSA 
device which IMHO moves your data to /dev/null or something similar 
useful ;)
So doing anything with ALSA/OSS can not work with the internal dsp. To 
access the internal dsp you have (using the 45 Release -> a little bit 
old) this gstreamer plugins available:
Nokia770-45:~# gst-inspect-0.8 |grep "dsp"
dspaac:  dspaacsink: DSP AAC Sink
dsppcm:  dsppcmsink: DSP PCM Sink
dspmpeg4sink:  dspmpeg4sink: DSP MPEG4/H.263 Sink
dspfbsink:  dspfbsink: DSP FB Sink
dspamr:  dspamrsink: DSP AMR Sink
dspmp3:  dspmp3sink: DSP MP3 Sink
May be the pcm sink is sufficient for you?
Another solution will be to build the esdsink yourself...
