Hi all!
Here some problems when referring to QSA calls.

- snd_pcm_plugin_params fails with error "invalid argument", though the pcm handle is valid and the 
snd_pcm_channel_params_t structure is initialized;

- also, snd_pcm_plugin_params fails if the format is set to SND_PCM_SFMT_FLOAT_LE or SND_PCM_SFMT_FLOAT_BE;

- snd_pcm_channel_status_t: the stime member is always to 0, though the time member in snd_pcm_channel_params_t is set 
to 1.

Where can be the problem? 
Thank you very much!

G.
