In the patch
+ /* Fsref can be 32000, 44100 or 48000. */
+ fs = params_rate(params);
+
+#ifndef CONFIG_SFFSDR_FPGA
+ /* Without the FPGA module, the Fs is fixed at 44100 Hz */
+ if (fs != 44100) {
+ pr_debug("warning: only 44.1 kHz is supported without SFFSDR
FPGA module\n");
+ return -EINVAL;
+ }
+#endif
You may want to consider modifying capture/playback rates (defined by
PCM3008_RATES). I believe ALSA check and printout a warning message
if the rate is not supported. Also, you won't be able to take advantage
of
ALSA's automatic rate conversion with this implementation.
