Receiver cards based on SAA7134 or similar chips capable of transferring sound over PCI bus (module saa7134_alsa) have sample rate fixed at 32000 Hz. KRadio r497 is not able to handle this, I am not sure about capturing but
when playback by capture is selected the sound is played back at wrong (higher) speed and of course contains dropouts. Possibility to select arbitrary sample rate for capturing would be nice. KRadio shall also watch the check actual sample rate of the captured stream which might not be the same as requested one.
