I found a solution that works on the P7:
In the /data/cust/prop/local.prop
Add following lines just before a #:
ro.config.hw.security_volume = 11
ro.config.ce_authenticate = 1
So at the end:
# Ro.config.hw.security_volume = 11
# Ro.config.ce_authenticate = 1
Save the file, restart phone.
Volume is significantly higher. [emoji2]
