In my understanding, such functionality should be in user-land. Drivers should just transfer samples from/to application to/from devices, should do nothing others.

For this issue, I assume that users utilize 'plughw' plugin. Actually I test drivers with aplay/arecord and this plugin. But recently, most users use Desctop Environment such as GNOME, KDE. The sound envoronment of them are already based on PulseAudio. So I want PulseAudio to adjust the mismatch between applications and actual devices. > However, if this means a lot of extra trouble/work for you, we could > write a special profile set file in PulseAudio for firewire devices > that is more adapted to your driver. I hope it. What should I do for this idea? Regards Takashi Sakamoto o-takashi at sakamocchi.jp
