[asus-port] A620 and sound: Invalid argument

I'm trying to get sound working on my PDA. It works well with
precompiled kernel, avaliable at
http://www.handhelds.org/moin/moin.cgi/MyPal620Download , but I want
to build more modern kernel (aniway, I need gnueabi support which is
turned off in that kernel). If I complie it myself, sound doesn't work
and I get:

pda dev # cat /usr/bin/yes >> /dev/sound/dsp
cat: write error: Invalid argument

I have tried 2.6.20-hh2 kernel and 2.6.19-hh9 (because 2.6.19-hh8
doesn't want to compile and as I understood patches for A620 were
included in hh9). I used my own .config and config from
/proc/config.gz from that working prebuilt kernel.

I have tested that under GPE image from
http://www.handhelds.org/moin/moin.cgi/MyPal620Download adn under
gentoo linux 2007.

May be somebody knows where it breaks? Where should I search for the
reason or how to build that 2.6.19-hh8 kernel with working sound?
