Many TVs and A/V receivers don't work with this bit set. Problem was confirmed using: Onkyo TX-SR605, Sony BRAVIA KDL-52X3500, Sony BRAVIA KDL-40S40xx. In theory this bit shouldn't affect audio engine when feeding it with data, however it seems it does. Driver fglrx doesn't set that bit in any of the above cases. This fixes a regression introduced by 3.5-rc1. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
