QOS ACL Set DSCP

I am having an issue setting / changing the DSCP value with CBS350 switches. I have an IPv4 Access List associated with a QOS policy to "set dscp 34" and that ingress policy is mapped on all ports of the switch. When pulling a wireshark on one of the ports of the switch I am seeing that packets which match the ACL are not having their DSCP values changed, they are the original DSCP values. 

Full config is attached but here is a sample of the ACL and set DSCP

ip access-list extended "Dante RTP"
permit ip any 239.69.1.1 0.0.255.255 ace-priority 10
permit ip any 239.255.0.0 0.0.255.255 ace-priority 20
permit ip 10.0.99.0 0.0.0.255 any ace-priority 30
permit ip 10.0.87.0 0.0.0.255 any ace-priority 40
exit
class-map "Dante RTP Map" match-any
match access-group "Dante RTP"
exit
policy-map "Dante RTP Policy"
class "Dante RTP Map"
set dscp 34
exit
exit

 

...and that policy is bound to every interface on the switch...

 

interface GigabitEthernet1
service-policy input "Dante RTP Policy" default-action permit-any
spanning-tree cost 2000000
switchport access vlan 89
!

 

Take a look at the attached config and Wireshare capture showing that traffic from 10.0.87.xxx is still showing DSCP values that are not 34 which should be the case with the class mapping. 

Thoughts?
