I'm the Mandriva PulseAudio maintainer. Most distros are now shipping PA
by default now so I doubt your problem will be specific to Mandriva :)
However, I'm not expert enough in the ALSA API to know specifically what
snd_pcm_hw_params_any() actually does, but I'd imagine (this is just a
guess) that this is something that is either not implemented in the
IOPLUG system (on which the pulseaudio alsa plugin builds) or something
not implemented in the pulseaudio alsa plugin itself.
Hopefully someone more versed in this can explain the reason why it
