"There were two relevant changes made to the ALSA API fairly recently (I was
unable to determine when). The driver is indeed using older ALSA but it is
much easier to patch the driver than to downgrade ALSA.
1) sound/driver.h no longer exists and is no longer needed.
2) they changed the signature of snd_card_create().
You can find a patch that addresses both of these items at
http://nylen.tv/wavepro-alsa-api.patch."
Copied the patch to the ./src directory and applied it. Not compiled yet.
