Get multiple lines from terminal output

I want to extract the ports for each device on the below:

        [Out] Headphones: Headphones (priority 200, latency offset 0 usec, available: yes)
            properties:
                
    active port: <[Out] Headphones>

I can get each device index with:

pacmd list-sinks | awk '/index:/ {print $0}

or with:

pacmd list-sinks | grep -e index

which results in:

    index: 0
    index: 1
    index: 2
  * index: 3

How can I go beyond that and compose commands to extract something like the lines bellow?

    index: 0
        ports:
                [Out] HDMI3: HDMI3/DP3 Output (priority 700, latency offset 0 usec, available: no)
    index: 1
        ports:
                [Out] HDMI2: HDMI2/DP2 Output (priority 600, latency offset 0 usec, available: no)
    index: 2
        ports:
                [Out] HDMI1: HDMI1/DP1 Output (priority 500, latency offset 0 usec, available: yes)
  * index: 3
        ports:
                [Out] Speaker: Speaker (priority 100, latency offset 0 usec, available: unknown)
                [Out] Headphones: Headphones (priority 200, latency offset 0 usec, available: yes)

pacmd list-sinks | awk '/index/ { print } /active port:/ { pnt=0 } /ports:/ { print;pnt=1 } pnt==1 && /\[Out\]/ { print }'

Print the index line, then when we see "ports:", set a variable pnt to 1, print the line and skip to the next line. When pnt is equal to one and the line contains "[Out]", print the line. When we see "active port:" reset the pnt variable back to 0.
