To get audio streaming, you need to change the audio output in pulseaudio to use the created "Network-Displays" sink.

To use it, you will need:

    openh264 or x264 [gst-plugins-ugly x264_148]
    For audio supporting using AAC one of fdkaacenc, faac or avenc_aac [faac]
    NetworkManager version > 1.15.2
    
    no usable wifi adapters found - please verifiy wifi is enabled and wifi p2p operations are available in both networkmanager and wpa_supplicant
    
    Wi-Fi P2P is an optional component that needs to be enabled in the
wpa_supplicant build configuration (.config). Here is an example
configuration that includes Wi-Fi P2P support and Linux nl80211
-based driver interface:

CONFIG_DRIVER_NL80211=y
CONFIG_CTRL_IFACE=y
CONFIG_P2P=y
CONFIG_AP=y
CONFIG_WPS=y

CONFIG_WPS2=y ??
