* Driver p16v chips
- * Version: 0.22
+ * Version: 0.25
*
* FEATURES currently supported:
* Output fixed at S32_LE, 2 channel to hw:0,0
* Integrated with snd-emu10k1 driver.
* 0.22
* Removed #if 0 ... #endif
- *
+ * 0.23
+ * Implement different capture rates.
+ * 0.24
+ * Implement different capture source channels.
+ * e.g. When HD Capture source is set to SPDIF,
+ * setting HD Capture channel to 0 captures from CDROM digital input.
+ * setting HD Capture channel to 1 captures from SPDIF in.
+ * 0.25
+ * Include capture buffer sizes.
*
* BUGS:
* Some stability problems when unloading the snd-p16v kernel module.
