ok, I fixed that by not using snd_pcm_start() at all. Thanks for the hint.
I still have issues which I find pretty strange though:

The very same application binary always buffer underruns on my x86-64 =

system while it works (almost) perfectly (at least w/o buffer underruns) =

on my smaller i586 system.

Anyone can imagine what could cause that?

Thanks,
