From 3ac9b0acc34fbe56e2d31b8f2f7e59d45c53cb3b Mon Sep 17 00:00:00 2001 From: Adrian Knoth Date: Fri, 5 Jul 2013 11:28:13 +0200 Subject: ALSA: hdspm - AES32: Ignore float/int format bit As mentioned in the comment, the AES32 cards must not set the format bit, since it is used to indicate the preferred sync setting instead. We hence simply skip the corresponding part in the hw_params function.
