Sure, you have three choices:

1. Enable network support and use a GUI client on a non-headless system
(e.g. PULSE_SERVER=<headless_ip> pavucontrol) and pick a 5.1
Configuration profile.

2. Use "pacmd list-cards" to see a list of card profiles, then then use
"pacmd set-card-profile idx profile" to set a 5.1 profile

3. Set default-sample-channels=6 in /etc/pulse/daemon.conf
